A Colorado business entity search confirms name availability and shows the public record of any LLC or corporation registered in the state. It is free and runs on the Secretary of State's database.
Colorado is one of the cheapest and most administratively straightforward states, with one operational quirk: it is online only.
Where the official Colorado business search lives
https://www.sos.state.co.us/biz/BusinessEntityCriteriaExt.do
Run by the Colorado Secretary of State. Free, no login. Search by entity name, ID number, trademark or trade name.
What the official search will not tell you
- Who owns the company. Colorado does not require member or manager names on the Articles of Organization.
- Trademark clearance. State distinguishability is not a trademark search, though Colorado's database does include registered state trademarks.
- Tax standing. Colorado Department of Revenue standing is tracked separately.
- Local licensing. City and county requirements do not appear here.

Step by step
Step 1. Open the Business Database Search
Go to sos.state.co.us and open the Business Database Search. No account is needed.
Step 2. Search by name or ID
For a name check, search the distinctive words rather than the full legal string.
Step 3. Try variants
Singular, plural and alternative spellings. Colorado blocks names that are not distinguishable.
Step 4. Read the status
"Good Standing" is the status you want. "Delinquent" means an overdue periodic report.
Step 5. Open the filing history
The entity summary shows the ID number, formation date, registered agent, principal address and every filing, all viewable free.
Colorado entity status decoder
- Good Standing. Registered and current on the periodic report.
- Delinquent. The periodic report is overdue. The entity still exists but is not current, and cannot obtain a Certificate of Good Standing.
- Administratively Dissolved. Colorado dissolved the entity after prolonged delinquency. Reinstatement is possible by filing what is owed plus a fee.
- Voluntarily Dissolved. The owners closed it deliberately.
Colorado's practical details
Colorado is online only. There is no paper filing option for formation or for the periodic report. That is convenient for international founders, since nothing needs posting.
The periodic report is $25, due in your anniversary month, with a window that runs from two months before through two months after. Miss the window and the entity becomes Delinquent, with a late fee to fix it.
| Colorado | Wyoming | Michigan | |
|---|---|---|---|
| Filing fee | $50 | $100 | $50 |
| Annual fee | $25 | $60 | $25 |
| Filing method | Online only | Online or mail | Online or mail |
| Deadline | Anniversary month, 5-month window | Anniversary month | 15 February |
| 5-year state cost | about $175 | about $340 | about $175 |
If the name is available, or taken
Available. Reserve it for 120 days, or file and secure it at registration.
Taken. Check whether the existing entity is Administratively Dissolved. Otherwise change a distinctive word.

Colorado business entity search for non-US founders
The database is public and free worldwide, and non-residents can form and own a Colorado LLC without visiting the US. The online-only filing system suits international founders well, since nothing has to be mailed.
Against Wyoming, Colorado is comparable on cost but does not offer the same owner privacy positioning, and is less familiar to banks reviewing non-resident applications. You need a registered agent with a Colorado street address either way.
