Colorado will not take a commercial mailbox or a P.O. Box as the registered-agent street

What Colorado actually requires

C.R.S. § 7-90-701 is Colorado’s registered-agent rule. Every domestic entity with a constituent filed document on the Secretary of State record, and every foreign entity authorized to transact business or conduct activities here, shall continuously maintain in this state a registered agent. That agent is an individual who is eighteen years of age or older whose primary residence or usual place of business is in this state; a domestic entity having a usual place of business in this state; or a foreign entity authorized here that has a usual place of business in this state. An entity having a usual place of business in this state may serve as its own registered agent. Any document that appoints a registered agent shall contain a statement that the person has consented to being so appointed. That is the sentence this page is built on. New Jersey wants a street and will not take a P.O. Box alone. Ohio files a written acceptance and cancels the articles if you miss the 30-day statutory-agent notice. Illinois gives you 60 days after a resignation, then you are not in good standing. Georgia wants the registered office at the same street as the agent and will not let an entity be its own agent. Florida files a written acceptance and posts a 10–noon / 2–4 clock. Arizona waits on a signed acceptance at the Corporation Commission. Delaware bans a virtual-only agent. Nevada makes a commercial agent register at ten companies. Wyoming bans UPS stores and virtual addresses. New York already names the Secretary of State as the agent. Pennsylvania files a registered office, not a registered agent. We print that contrast once. We do not invent a Colorado written-acceptance form we did not retrieve.

The Secretary of State registered-agent FAQ, retrieved September 8, 2026, is the street rule this page is built on. A registered agent is an individual or a company that is your official point of contact in Colorado to receive service of process, legal and state documents, and relay those communications to the business. Colorado law requires the registered agent to have a physical address in Colorado. Almost all entities on record must keep that Colorado address, even if the business sits in a different state. The Secretary of State cannot be appointed as a registered agent. You may appoint only one individual or one entity. The agent must consent. A street address is a place a person can walk up to, like 123 Main Street. We do not treat a P.O. Box as that Colorado street.

FAQ A6 is the usual-place-of-business sentence. “A usual place of business located in Colorado” means that the registered agent has a physical street address located in Colorado and that the place is customarily open during normal business hours. This is a place where the registered agent can physically in person accept documents for the entity. Commercial or P.O. Box addresses cannot be used as a registered agent's physical street address. FAQ A7 is the mailing line. If the agent has a mailing address different from the physical street, enter it in the mailing-address section, not on the street line. That different mailing address may be a commercial or P.O. Box, but it must also be located in Colorado. We print both sentences. We do not treat a commercial mailbox as the street because a mailing box sits next to it.

The same FAQ, and the Registered Agent Requirements Effective July 1, 2025 page, are the 2024 law-change sentences. An individual agent must be over the age of 18, must live in Colorado or keep a usual place of business here, and must hold a current, valid Colorado driver’s license or identification card, or verify residency with the office. A company agent must be in good standing on the Secretary of State record, must keep a usual place of business in Colorado, and, if it is foreign, must have authority to transact business here. The FAQ says an entity may serve as its own registered agent after it registers, and only if it is in good standing. That self-appointment is a two-step path: first name an eligible individual or another entity on the formation filing, then file a change to put the entity on its own agent line. We print that official two-step. We do not invent a one-click self-appointment the FAQ does not describe.

FAQ A4 is the passcode path. If the individual does not have a Colorado driver’s license or identification card, the office still lets that person serve after an alternative residency check. Request a registered-agent passcode. Attach one document that shows the Colorado street, for example a bank statement or a utility bill. The FAQ says the request is reviewed and, if approved, a passcode is emailed to the person who submitted the request. That passcode expires 45 calendar days after it is issued. FAQ A5 lists the documents the office will take: a utility bill, a bank or credit-card statement, a mortgage statement, government-issued correspondence, or a tribal ID, dated within the last 90 days, with a specific issue date, the person’s first and last name exactly as entered, and the complete physical street. Digital copies are acceptable. ZenBusiness’s Colorado page, last updated August 31, 2026, says the passcode will be mailed. The official FAQ says emailed. We print both. We do not pick a winner.

C.R.S. § 7-90-702 is how you change or drop the agent. An entity may change its registered agent, the registered-agent address, or the registered-agent name only by stating the different line on a statement of change under C.R.S. § 7-90-305.5, on a periodic report under C.R.S. § 7-90-501, or on a Secretary of State form prescribed for that change. If the agent’s own name or address changes, the agent files the statement of change and states that notice of the change was delivered to the entity. If the agent resigns or is no longer the agent, that person — or a legal representative — may file a statement of change that names the old line, the date the person resigned or otherwise ceased to be the agent, and a statement that notice was delivered to the entity. That resignation filing is effective on the thirty-first day after it is filed, or on a delayed date the filing names that is not earlier than the thirty-first day and not later than the ninetieth day, or on the effective date of a statement appointing a different person, whichever occurs first. The official fee table, revised July 1, 2024 and retrieved September 8, 2026, prices a statement of change changing the registered-agent information at $10 and a statement of change regarding resignation or other termination of registered agent at $10. Those dollars are online-only on that table. Paper is marked n/a.

The noncompliance FAQ, retrieved September 8, 2026, is the clock after a resignation. If a new registered agent is not appointed within thirty days after the resignation of the current registered agent, the entity will become Noncompliant. The statute’s thirty-first-day effective date and the FAQ’s thirty-day Noncompliant line are not the same sentence. We print both. We do not invent a third clock. An entity with a status of Noncompliant for sixty days will then become Delinquent if the appropriate form is not filed. FAQ A1 also says the record becomes Noncompliant if the entity does not file its periodic report on time or does not keep a registered agent on file.

C.R.S. § 7-90-704 is service of process. The registered agent is an agent of the entity authorized to receive service of any process, notice, or demand the law lets you serve on the entity. The registered agent is also the person to whom the Secretary of State may deliver forms, notices, or other documents for the entity, unless an organic statute says otherwise. If the entity has no registered agent, or the agent is not located under its registered-agent name at its registered-agent address, or the agent cannot with reasonable diligence be served, the entity may be served by registered mail or by certified mail, return receipt requested, addressed to the entity at its principal address. Service is perfected at the earliest of the date the entity receives the papers, the date shown on the return receipt if signed on behalf of the entity, or five days after mailing. That mail-to-the-principal-office path is a fallback. It is not the everyday job. FAQ A12 repeats the same mail sentence. Service on the Secretary of State is not the Colorado fallback. New York starts with the Secretary of State on the agent line. Colorado’s FAQ says the Secretary of State cannot be appointed as a registered agent.

C.R.S. § 7-90-707 prints a commercial-registered-agent listing statement: a registered agent may become listed as a commercial registered agent by delivering that statement to the Secretary of State, with the registered-agent name and address, an email address for Secretary of State notifications, and a list of the entities the agent represents at the time of filing. An editor’s note on the public-law text we retrieved September 8, 2026 says that section is effective ninety days following certification by the secretary of state. We did not retrieve that certification. We do not treat a live commercial-registered-agent register as open. We do not invent a Nevada-style ten-company bar from a section that still carries that editor’s note. Confirm the live name and street on the Business Database Search.

Colorado also files a periodic report. That filing is not the registered-agent job. C.R.S. § 7-90-501 puts the registered-agent name and registered-agent address, and the principal-office address, on every periodic report. The first report is due no later than the last day of the second calendar month following the first anniversary of the calendar month in which the constituent filed document, or the statement of foreign-entity authority, became effective. After a reinstatement or a curing of delinquency, that first-anniversary clock restarts from the month of that filing. Thereafter the report is delivered annually. Information on the report must be current as of the day it is delivered. The report shall not state a delayed effective date. Fail or refuse to deliver the report on or before the due date and pay the prescribed processing fee, and the entity is subject to a penalty under C.R.S. § 24-21-104(3).

The periodic-report FAQ, retrieved September 8, 2026, is the office’s plain-language window. Reporting entities — including limited liability companies, corporations, nonprofit corporations, and foreign entities — must submit a periodic report each year. The report must be filed electronically through the Secretary of State website. Find the reporting month on the entity’s Summary page under “Periodic report month.” The periodic report can be filed two months prior to that month or two months after without any penalty. The noncompliance FAQ says entities are given five months to file the periodic report. If the Periodic Report month is January, the due date is March 31. If the report is not electronically filed by that date, the entity’s status becomes Noncompliant and the late fee is assessed. An entity with a Noncompliant status for sixty days then becomes Delinquent. The periodic-report FAQ Q7 says the entity’s status will become Delinquent if a report is not filed. Those two FAQ pages are the office’s own words. We print both. File from the Business Database Search by opening the record and choosing File a Periodic Report. The file-a-form page is the same online path.

The official fee table, revised July 1, 2024 and retrieved September 8, 2026, prices a periodic report at $25 online. The periodic-report late-filing penalty is $50. A statement of change changing the registered-agent information is $10. A statement of change regarding resignation or other termination of registered agent is $10. A statement of correction correcting the registered-agent information is $10. A statement of correction that the registered agent has not consented is $10. A statement curing delinquency is $100. Reinstatement is $100. Articles of organization for a limited liability company are $50. A foreign-entity authority statement is $100. Certificates of good standing are free online. Those dollars are Secretary of State dollars. They are not the vendor’s year-1 card. A June 17, 2024 Secretary of State news release said the periodic-report fee moved from $10 to $25 on July 1, 2024. We print the live table, not the old $10 line.

C.R.S. § 7-90-901 is why a missed agent or a missed report can take the company off good standing. A domestic reporting entity may be declared delinquent if it does not pay a fee or penalty when due, if it does not comply with the periodic-report part, or if it does not comply with the registered-agent part. A foreign reporting entity may be declared delinquent on those same grounds, plus a false statement of foreign-entity authority, or a certificate from its home office that it no longer exists. Delinquency is not the registered-agent job. It is what happens when the registered-agent job, or the periodic report, is not kept. Confirm the live name and street on the Business Database Search before you treat a marketing city as current. Headquarters is not the registered office. The Secretary of State desk at 1700 Broadway, Suite 550, Denver, CO 80290, is not a vendor suite.

Cited prices, retrieved September 8, 2026

We print what the company’s official registered-agent page said on the retrieval date. No company publishes a different Colorado registered-agent price from the national card, except where we note a Colorado-page renewal line. 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 8, 2026 from northwestregisteredagent.com/registered-agent and the Colorado product page. First year free only if you form through them; we do not treat that bundle as the standalone price.
• Bizee: official registered-agent page: free first year with formation; standalone $149/year; year two $149/year. Retrieved September 8, 2026 from bizee.com/business-management/registered-agent. A bizee.com/llc/colorado-registered-agent URL returned 404 the same day. We do not invent a Colorado-only price from a missing page.

Footnote: auto-renews at the purchase rate; “The renewal rate is subject to change.” Retrieved from legalzoom.com/…/registered-agent-overview.html. The Colorado registered-agent article URL returned 404 the same day. We do not invent a street from a missing page.
• ZenBusiness: official Colorado page: “Starts at $99 + CO state fees” for the first year. Renews at $199/year, subject to change. That Colorado page was last updated August 31, 2026. The same national page says they currently do not offer registered-agent service to PLLCs or nonprofits. That is their national exclusion, not a Colorado statute. Retrieved September 8, 2026 from zenbusiness.com/registered-agent and the Colorado product page. That Colorado page publishes no ZenBusiness street or city.

A change of agent is a separate Secretary of State filing. We cite the official fee table, retrieved September 8, 2026, not company blogs. The statement of change changing the registered-agent information is $10. The periodic report is $25. The late-filing penalty is $50. ZenBusiness’s Colorado page prices those same two filings at $10 and $25 as of August 2026. That matches the official table. We print the official dollars.

Who publishes a Colorado 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 Database Search before you file. Headquarters is not the registered office. The Secretary of State’s Denver contacts are not vendor suites.

• Northwest. The Colorado FAQ answers “Where is Northwest’s registered office in Colorado?” with “We accept and scan all of our Colorado clients’ documents on-site at our registered office in Boulder, CO.” The office-locations page lists Boulder, CO 80302, Boulder County, and says they leave the street off this list. No street is published. Same-day local scans and instant notices are vendor-claimed. We have not been to a Boulder office.
• Bizee. Claims owned offices in all 50 states. The official registered-agent page names no Colorado street. The Colorado product URL we tried returned 404 on September 8, 2026. The contact page lists 17350 State Highway 249, Suite 220, Houston, TX 77064 as headquarters. That address is not a Colorado registered-agent street.
• LegalZoom. The official registered-agent overview does not publish a Colorado street. The Colorado registered-agent article URL returned 404 on September 8, 2026. We do not invent a suite. We do not treat a LegalZoom virtual-mail street as the registered-agent street.
• ZenBusiness. The Colorado product page publishes no ZenBusiness street or city. The product page shows a “Colorado Secretary of State” contact at 1700 Broadway, Suite 550, Denver, CO 80290, with office hours Monday–Friday 8:00 a.m.–5:00 p.m. Those hours and that suite are the Secretary of State, not ZenBusiness’s registered office. We do not treat 1700 Broadway as their street. We will not invent a suite.

If you are your own 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 and its Colorado street. Northwest names Boulder, ZIP 80302, Boulder County, and no street. Bizee, LegalZoom, and ZenBusiness publish no Colorado street. We label every city vendor-claimed. We have not been to those offices. Use the Business Database Search.

In-state office and the July 2025 check

Colorado wants an in-state person or an authorized company in good standing, a street that is a residence or a usual place of business, and a consent statement on the appointing filing. A commercial mailbox is not that street. A P.O. Box is not that street. An individual agent needs a current Colorado driver’s license or identification card, or the office’s 45-day passcode after a street-proof review. Resignation is effective on the thirty-first day, unless a new agent is named sooner. Miss the thirty-day appointment after a resignation and the noncompliance FAQ marks the record Noncompliant. Stay Noncompliant for sixty days and the record becomes Delinquent. The periodic report is due in a five-month window around the periodic-report month and costs $25. Colorado does not run a live Nevada-style ten-company commercial-agent register on the text we could read, and it does not post a Florida-style 10–noon / 2–4 clock. Northwest claims Boulder, ZIP 80302, and no street. LegalZoom’s official overview names no Colorado street. ZenBusiness’s Colorado product page names no ZenBusiness street. The 1700 Broadway, Suite 550 line is the Secretary of State. Bizee names no Colorado street. Process Score has not been to those offices. We do not treat a company 9-to-5 line as C.R.S. § 7-90-701.

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.
• Northwest: “We scan every document you receive right where you receive it—in our office.” The Colorado page adds same-day local Boulder scans. Their mail-forwarding extras are 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. Junk-mail shredding is not the job we score.
• 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 Colorado statute.

Home-address privacy

A commercial organizational agent is how most Colorado owners keep a home off the agent line. The Secretary of State still publishes whatever other addresses you put on a formation filing or a periodic report. Privacy of the agent line is not privacy of every field. Confirm the live line on the Business Database 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 C.R.S. § 7-90-701.
• It does not treat the periodic-report Noncompliant and Delinquent clocks as optional. The office says a missed report, or a missing agent, can take the record off good standing.
• It does not treat a Houston headquarters as a Colorado street.
• It does not treat 1700 Broadway, Suite 550 as a vendor suite. That contact is the Secretary of State.
• It does not invent a Colorado-only price a company did not print.
• It does not invent a ZenBusiness Colorado street the product page does not publish.
• It does not treat the periodic report as the registered-agent job.
• It does not treat a commercial mailbox or a P.O. Box as the registered-agent street because a mailing line sits next to it.
• It does not treat C.R.S. § 7-90-707 as a live commercial-registered-agent register. The public-law text we retrieved still carries an editor’s note that the section is effective ninety days following certification by the secretary of state. We did not retrieve that certification.
• It does not treat the old $10 periodic-report fee as today’s dollars. The live table is $25.
