Connecticut bans a P.O. Box on the agent’s business and residence street — but the separate Connecticut mailing line may be a P.O. Box

What Connecticut actually requires

Conn. Gen. Stat. § 34-243n is the Connecticut LLC registered-agent statute. Each limited liability company, and each registered foreign limited liability company, shall designate and maintain a registered agent in this state. The designation of a registered agent is an affirmation of fact that the agent has consented to serve as agent. A domestic company’s agent is a Connecticut resident, or a listed Connecticut or authorized foreign entity. A foreign company’s agent may also be the Secretary of the State and that office’s successors. The agent is appointed by filing a written appointment with the Secretary of the State. If the agent is a natural person, the filing lists the business and residence addresses. If the agent is an entity, it lists the principal office. In each case the address shall include the street and number or other particular designation. Each written appointment shall also be signed by, if other than the Secretary of the State, the registered agent therein appointed. A registered agent shall have a place of business in this state. The only duties under the LLC chapter of an agent that has complied are the duties in Conn. Gen. Stat. § 34-243n(f). That is the LLC sentence. We print it. We do not invent a shorter one. The official CGA chapter is the cite we use. A Justia mirror of the same section also exists.

Conn. Gen. Stat. § 34-247 is what the certificate of organization must say. It must name a registered agent appointed in compliance with § 34-243n, along with the street address and mailing address in this state of the company’s registered agent. That is the two-line split in the statute. The live domestic LLC forms and fees page prices Certificate of Organization, “including appointment of statutory agent,” at $120. Conn. Gen. Stat. § 34-243u prices the same paper at one hundred twenty dollars. Those two numbers match. The fee table uses statutory agent. The statute uses registered agent. We print both. We do not invent a third name.

The live Change of Agent paper is form BUS-09, Rev. 1/2024. The face says Secretary of the State of Connecticut. For an individual agent it asks for a business address and a Connecticut residence address. Both lines say No P.O. Box. For a business agent it asks for a Connecticut business address and says No P.O. Box. Then it requires a Connecticut mailing address of registered agent for all LLCs and domestic stock corporations. That line says P.O. Box is acceptable. The instructions add that the entity may not appoint itself as its registered agent. The appointed agent must sign acceptance of appointment. The face prices the paper at $50, with a $20 exception for nonstock nonprofit corporations. Conn. Gen. Stat. § 34-243o is how the company changes the line. The company files a change of address of agent certificate or a change of agent certificate. A new-agent certificate must be signed by the new agent, unless the agent is the Secretary of the State. A new designation is an affirmation of fact that the agent consented. The live Update Business Agent page, dated June 26, 2024, prices the same change at Non-Stock Corp. $20 and All Others $50. Those three sources match on the $50 / $20 pair.

The live Change of Agent’s Address paper is form BUS-003, Rev. 1/2024. It is not the paper that names a new agent. The business address line says P.O. Box is NOT acceptable. The Connecticut residence address line says P.O. Box is NOT acceptable. The Connecticut mailing address line, required for all LLCs and domestic stock corporations, says P.O. Box IS acceptable. That is the unique Connecticut split. We print it. We do not invent a shorter one. Conn. Gen. Stat. § 34-243q gives the agent thirty days to file a name or address change.

Conn. Gen. Stat. § 34-243p is how an agent steps down. The agent files a certificate of resignation. The certificate takes effect on the earlier of the thirty-first day after the day it is filed or the date a new registered agent is designated. The agent shall immediately furnish the company with notice of the filing date. The live LLC fee table prices Resignation of Agent at $50. Conn. Gen. Stat. § 34-243u prices a notice of resignation at fifty dollars. Those two numbers match. ZenBusiness’s Connecticut page, last updated August 26, 2025, prints the same 31st-day end and the same $50 filing, with a $20 nonprofit and limited-partnership exception. Those vendor sentences match the statute and the table we retrieved. Northwest’s Connecticut page talks about a Statement of Resignation of Registered Agent sent to the Commercial Recording Division. We print the vendor name. The live office on the forms we opened is the Business Services Division at the Secretary of the State.

Conn. Gen. Stat. § 34-243r is how court papers are handed over. A company may be served by leaving a true and attested copy with the registered agent, or at that agent’s usual place of abode in this state. If the company ceases to have an agent, or the agent cannot with reasonable diligence be served, mail may go to the principal office shown on the most recent annual report. Service on the Secretary of the State as a foreign company’s agent is fifty dollars under Conn. Gen. Stat. § 34-243u.

Conn. Gen. Stat. § 34-247k is the yearly Secretary of the State paper this page will not confuse with the agent job. A limited liability company shall deliver an annual report by electronic transmission. The report states the name of the company, the street and mailing addresses of its principal office, the name and address of the registered agent, and other required lines. The first report must be filed after January first and before April first of the year following the calendar year in which the company was formed. Later reports use that same January-to-April window. The live domestic LLC forms and fees page prices Annual Report at $80 and says it is filed online annually from January 1 to March 31. The domestic annual-report fees page prices the LLC annual report at $80. Conn. Gen. Stat. § 34-243u prices an annual report concerning any year on or after July 1, 2020 at eighty dollars. Those three numbers match. Bizee’s Connecticut page says the annual report is due by the last day of the anniversary month of formation. That is Bizee copy. An older Secretary of the State annual-report FAQ said LLC reports used the anniversary month before 2018, and then moved to January 1 through March 31. We print the live statute, the live fee table, and the vendor sentence. We do not invent a fourth date that makes them agree.

Whether that $80 paper can change the agent is a live conflict. We print the sources. We do not invent a winner. The older annual-report FAQ asked, “Can I change my registered agent on the annual report?” The answer was no. A separate change of agent must be filed, because the agent must accept appointment. The same FAQ said the registered-agent information and the business name cannot be changed on the annual report. The live Update Business Agent page, dated June 26, 2024, says you can also update agent info when you file your annual report. The live File Annual Report page lists registered-agent name, email, phone, business, residence, and mailing lines. The live Amend my Annual Report page, dated January 29, 2025, lists “Update a registered business agent” as one thing that page can do. The change forms already submitted page says some annual-report changes can be made within 30 days of the due date for an $80 filing fee, and then prices a separate Change of Agent at $20 / $50. Conn. Gen. Stat. § 34-247k (g), added by P.A. 24-111 effective January 1, 2025, says if any required annual-report information except the company name changes, the company shall file an amended annual report. The filing fee for that amended report is twenty-five dollars. The knowledge-base page we opened still prints $80 for those thirty-day annual-report changes. We print $25 from the statute and $80 from the live article. We do not invent a third fee that makes them agree. Putting a new name on an $80 paper is still not the registered-agent job. The job is taking court papers at the Connecticut street.

Conn. Gen. Stat. § 34-267g is the missing-report and missing-agent clock. If a company is more than one year in default of its annual report, the Secretary of the State may send an electronic-mail notice. The company then has three months to file the report or the office files a certificate of dissolution by forfeiture. The same three-month email clock applies if the company has failed to maintain a registered agent for service. Dissolution by forfeiture does not terminate the authority of the registered agent. Stay without an agent, or miss the report for more than a year, and that is the path we opened. Bizee’s Connecticut page says Connecticut can administratively dissolve an LLC that does not have an active registered agent. We print the forfeiture statute we opened.

The public lookup sits at service.ct.gov/business/s/onlinebusinesssearch. Confirm the live line on the Business Records Search before you treat a marketing city as current. Headquarters is not the registered office. The Secretary of the State’s Hartford contacts are not a vendor suite. The older CONCORD inquiry URL we opened returned business.ct.gov. A guessed business.ct.gov search path we tried sent us to the Connecticut DMV. We do not cite that DMV page.

Paper filings go to Business Services Division, Connecticut Secretary of the State, P.O. Box 150470, Hartford, CT 06115-0470. Delivery is 165 Capitol Avenue, Suite 1000, Hartford, CT 06106. The phone on the live forms is 860-509-6003. The email on those forms is bsd@ct.gov. The website on those forms is business.ct.gov. The live Business Services Division page posts hours 8:30 a.m. to 4:00 p.m. and repeats 165 Capitol Avenue, Suite 1000. ZenBusiness’s Connecticut page prints 860-509-6200. We print both phones. We do not invent a third number that makes them agree. Those hours are the Secretary of the State’s hours. They are not a registered-office clock. Connecticut does not post Florida-style 10–noon / 2–4 windows. We do not treat a company 9-to-5 line as the statute. An older FAQ still lists 30 Trinity Street and crd@ct.gov. Those are old Commercial Recording Division contacts. The live forms we opened use Capitol Avenue and bsd@ct.gov.

Cited prices, retrieved September 17, 2026

We print what the company’s official registered-agent page said on the retrieval date. No company publishes a different Connecticut registered-agent price from the national card, except where we note a Connecticut-page sentence. We do not invent a renewal.

• Northwest Registered Agent: official page: “$125 Per Year.” Same price in year two on the national card. Five or more states is $100 a year per state. Retrieved September 17, 2026 from northwestregisteredagent.com/registered-agent and the Connecticut product page. First year free only if you form through them; we do not treat that bundle as the standalone price. The Connecticut page says they accept and scan documents on-site at their registered office in Glastonbury, CT. The same page also sells five free scans of regular business mail a year, with extra scans at $15 a document. Those extras are a different product. We do not grade those extras as the registered-agent job. The same page talks about the Secretary of State – Commercial Recording Division. That is vendor copy. The live forms we opened say Secretary of the State and Business Services Division.
• Bizee: official registered-agent page: free first year with formation; standalone $149/year; year two $149/year. Retrieved September 17, 2026 from bizee.com/business-management/registered-agent. A bizee.com/llc/connecticut-registered-agent URL returned 404 the same day. The live Connecticut page is bizee.com/llc/connecticut/registered-agent. That page names a $120 Certificate of Organization. The live LLC table we retrieved is $120. Those two numbers match. The same page says the annual report is due by the last day of the anniversary month of formation. The live fee table we retrieved is January 1 to March 31. After a free first year with formation, the official card says the agent service is $149 a year. The same page talks about a physical street during normal business hours. That is Bizee copy. We print those vendor sentences. We do not invent a Connecticut-only price from a missing hyphenated URL.
• LegalZoom: official overview retrieved September 17, 2026: “Get registered agent services for $249/year.” Product card: $249/year. Retrieved from legalzoom.com/…/registered-agent-overview.html. The live Connecticut article is legalzoom.com/articles/registered-agent-in-connecticut, updated April 30, 2026. That article publishes no LegalZoom Connecticut city or street. It prints Secretary of the State contacts at P.O. Box 150470 and 165 Capitol Avenue, Suite 1000. A legalzoom.com/articles/connecticut-registered-agent URL returned 404 the same day. The article’s FAQ says the agent’s business address must be a physical street, and the mailing address can be a P.O. Box. That vendor sentence matches live forms BUS-09 and BUS-003. The same article talks about typically Monday to Friday, 9 a.m. to 5 p.m. That clock is LegalZoom copy. The change-of-agent how-to casually says Secretary of State. We print those vendor sentences. We do not invent a suite or a higher year-two number.
• ZenBusiness: official Connecticut page: first-year and renewal dollars are the national card. The national page says $99 + state fees for the first year and renews at $199/yr, subject to change. The Connecticut page, last updated August 26, 2025, talks about $100 to a few hundred dollars a year as a market range. That range is not a ZenBusiness price. We keep the national card. A zenbusiness.com/connecticut-resident-agent/ URL returned 404 the same day. The live Connecticut page is /connecticut-registered-agent/. That page prices Change of Agent at $50 for most business types and $20 for nonprofits, prints a 31-day resignation, and prices that resignation at $50, or $20 for nonprofits and limited partnerships. Those lines match the live table and Conn. Gen. Stat. § 34-243p. The national page says they currently do not offer registered-agent service to PLLCs or nonprofits. That is their national exclusion, not a Connecticut statute. Retrieved September 17, 2026 from zenbusiness.com/registered-agent and the Connecticut registered-agent page.

A change of registered agent is a separate Secretary of the State filing unless you use a later annual-report path the live knowledge base still describes in more than one way. We cite Conn. Gen. Stat. § 34-243o, the $50 / $20 BUS-09 row, the $80 LLC annual report, and the $25 amended-report fee in Conn. Gen. Stat. § 34-247k (g). The yearly paper can list the agent. It is still not the registered-agent job.

Who publishes a Connecticut street

A city is not a registered office. We print only the streets the companies publish for registered-agent use. We do not invent the rest. Confirm the live name and street on the Business Records Search before you file. Headquarters is not the registered office. The Secretary of the State’s Hartford contacts are not vendor suites.

• Northwest. The Connecticut product page says they accept and scan documents on-site at their registered office in Glastonbury, CT. The office-locations page lists Glastonbury, CT 06033 Hartford County, and does not print a street. No street is published. The two city lines match on Glastonbury. We have not been to a Glastonbury office. Northwest also sells extra mail scans from that location. Those extras are a different product.
• Bizee. Claims owned offices in all 50 states. The official registered-agent page names no Connecticut street. The live Connecticut product page names no Connecticut street. The hyphenated Connecticut URL we tried returned 404 on September 17, 2026. The contact page lists 17350 State Highway 249, Suite 220, Houston, TX 77064 as headquarters. That address is not a Connecticut registered-agent street.
• LegalZoom. The official registered-agent overview does not publish a Connecticut street. The live Connecticut article names no LegalZoom city or street. The second Connecticut article URL we tried returned 404 the same day. We do not invent a suite. We do not treat a LegalZoom virtual-mail street as the registered-agent street.
• ZenBusiness. The Connecticut registered-agent page publishes no ZenBusiness street or city. It prints Secretary of the State contacts at P.O. Box 150470, Hartford, CT 06115-0470 and 165 Capitol Avenue, Suite 1000, Hartford, CT 06106, telephone 860-509-6200. Those lines are office contacts. They are not ZenBusiness. The live forms we retrieved use 860-509-6003. We do not treat the Capitol suite as their office.

If you are your own registered agent, the street on the public record is often your home. If you hire a commercial registered agent, the agent line is that organization’s name. Northwest names Glastonbury on the product page and Glastonbury, CT 06033 Hartford County on the office list, and no street on either. LegalZoom publishes no Connecticut city. Bizee publishes no Connecticut street. ZenBusiness publishes the Secretary of the State’s Capitol Avenue suite. We label every published city vendor-claimed. Use the Business Records Search.

In-state office, the street-and-mailing split, and the $80 January-to-March paper

Connecticut wants a registered agent with a place of business in this state. An individual agent’s business and residence addresses must include a street and number, or another particular designation. Live form BUS-09 says no P.O. Box on those streets. The same form requires a separate Connecticut mailing line. A P.O. Box is acceptable on that mailing line. Change the agent on form BUS-09, $50 for most entities and $20 for a nonstock corporation on the live form and the Update Business Agent page. Resignation ends on the earlier of the 31st day or a successor. The LLC annual report is $80. The live table says January 1 to March 31. The statute says after January first and before April first. Those two windows match. Whether that paper can change the agent is a live conflict between an older FAQ, the 2024–2025 knowledge base, and the $25 amended-report fee in § 34-247k(g). Stay without an agent, or miss the report for more than a year, and the Secretary of the State may start a dissolution by forfeiture after a three-month email notice. Connecticut does not post a Florida-style 10–noon / 2–4 clock, and it does not run a Nevada-style ten-company commercial-agent register. Northwest claims Glastonbury, ZIP 06033, Hartford County. LegalZoom names no Connecticut city. ZenBusiness publishes P.O. Box 150470 and 165 Capitol Avenue, Suite 1000 — the Secretary of the State. Bizee names no Connecticut street. Process Score has not been to those offices. We do not treat a company 9-to-5 line as Conn. Gen. Stat. § 34-243n.

Service of process, not marketing mail

We grade scan-and-forward of service of process and official notices:

• Bizee: notifications by text and email; court papers mailed via FedEx with tracking; portal upload by employees. The Connecticut page talks about a physical street during normal business hours. That is Bizee copy. Contact-page support hours are Monday–Friday 9 a.m. to 6 p.m. CST. Those are support hours, not registered-office hours.
• Northwest: “We scan every document you receive right where you receive it—in our office.” The Connecticut page adds on-site scans at the Glastonbury office. Their extra mail-scan product is a different product. We do not grade those extras as a mailbox.
• LegalZoom: upload, email, and a postcard for urgent legal mail; they say they shred junk mail. The live Connecticut article names no LegalZoom city and a typical 9 a.m. to 5 p.m. line. Junk-mail shredding is not the job we score. That clock is not the statute.
• ZenBusiness: scan and upload to a dashboard; email; overnight the original for urgent legal notices. Their own FAQ says you cannot use the agent address as your business address. Their national product currently excludes PLLCs and nonprofits; that is their exclusion, not a Connecticut statute. The Connecticut page prints Secretary of the State contacts at 165 Capitol Avenue, Suite 1000. That suite is office copy. It is not Conn. Gen. Stat. § 34-243n.

Home-address privacy

A commercial registered agent is how most Connecticut owners keep a home off the agent line. The Secretary of the State still publishes whatever other addresses you put on a formation filing or an annual report. Privacy of the agent line is not privacy of every field. A Connecticut LLC must name an agent. It cannot leave that line blank. Confirm the live line on the Business Records Search.

Scorecards

What this page does not do

• It does not rank mailbox networks or virtual offices.
• It does not publish combined star ratings or a fake 4.8.
• It does not treat a company 9-to-5 line as Conn. Gen. Stat. § 34-243n.
• It does not treat the $80 January-to-March annual report as the registered-agent job. Live office pages still disagree about whether that report can change the agent.
• It does not invent a winner between the older FAQ that said the annual report cannot change the agent, the 2024–2025 knowledge base that says it can, and the $25 amended-report fee in Conn. Gen. Stat. § 34-247k (g).
• It does not invent a winner between the $25 amended-report fee in the statute and the $80 thirty-day annual-report change on the knowledge-base page.
• It does not treat a Houston headquarters as a Connecticut street.
• It does not treat 165 Capitol Avenue, Suite 1000, or P.O. Box 150470, as a vendor suite. Those contacts are the Secretary of the State.
• It does not invent a Connecticut-only price a company did not print.
• It does not invent a LegalZoom Connecticut street the live article did not print.
• It does not treat a P.O. Box as the business or residence street. The mailing line is the line that may be a P.O. Box.
• It does not invent a ten-company commercial-agent bar. Connecticut does not run that register.
• It does not pretend a Connecticut LLC may skip the agent. Conn. Gen. Stat. § 34-243n says the company shall designate and maintain one.
• It does not treat Bizee’s anniversary-month due date as the live window. The live table is January 1 to March 31.
• It does not treat Northwest’s extra mail-scan product as the registered-agent job.
• It does not casually rename the office Secretary of State in our voice. The official title is Secretary of the State.
