"Not registered" is the registry's answer at this moment. It is not a promise that the name can be bought at the standard price, since some unregistered names are reserved or sold at a premium. The buttons open Spaceship, a domain registrar, where the price is shown.

The state's Business Database Search takes a business name, trademark, trade name, ID number or document number. An advanced search narrows by a range of dates, by business name or by an individual's registrant name.

Each result lists the type of entity, date of formation, ID number, status, principal office address, registered agent and state of organization. The state's tips say to search one or two key words and leave out punctuation and the required ending.

What the published list covers

The search here reads "Business Entities in Colorado", a dataset the Colorado Department of State publishes on data.colorado.gov and updates daily. It includes dissolved, delinquent and withdrawn entities, each shown with its status.

For every entity it shows the name, entity type, status, formation date and the state's ID number. It does not show addresses or registered agents, which sit in the state's own search.

Owners and officers are a gap in the state record itself. The Secretary of State says entities are not required to file names of owners, officers, directors, members or managers.

How Colorado treats names after a status change

When an entity goes delinquent, dissolves or withdraws, the state adds "Delinquent", "Dissolved", "Withdrawn" or "Colorado Authority Terminated" to the end of its name. The original name is then free for another business to use, according to the Secretary of State.

That makes a status worth reading in every result. An entry marked Dissolved no longer holds its plain name.

What counts as a different name in Colorado

The statute requires each entity name to be distinguishable on the records. Periods, commas, the _ character, apostrophes and capital letters do not make a name distinguishable.

Different entity terms do. The Secretary of State says "ABC LLC" and "ABC Limited Liability Company" are different, and so are "ABC LLC" and "ABC INC". Added spaces, hyphens or parentheses also count.

The Name availability search leaves out trade names and trademarks. The state suggests contacting legal counsel before using a name very close to one on record.

Reserving and paying for a Colorado name

The Secretary of State's fee schedule lists Reservation of Name at $25. Reservations are good for 120 days, and a Statement of Renewal of Reservation of Name renews one at $25 online.

Articles of Organization are $50 for an LLC, and the LLC cost calculator adds that to the yearly Periodic Report at $25. A late Periodic Report carries a $50 penalty. For a business that wants a second name, the guide to fictitious business names compares the options.

Colorado name search questions

Is the Colorado secretary of state business search the same as this search?

No. The Secretary of State's Business Database Search is the official record and also shows the registered agent and principal office address. The search here reads the Business Entities in Colorado dataset on data.colorado.gov.

What is the 11-digit number on a Colorado entity record?

It is the entity ID number the Secretary of State's office assigns to identify a record. It is not the tax ID, and the state suggests searching by it when you can.

Can two Colorado businesses use the same trade name?

Yes. The Secretary of State says trade names are not distinguishable or unique, so more than one person can file the same trade name. A trade name statement costs $20 online.

Can a Colorado business sell or transfer its name?

No. Colorado statute does not allow a business to transfer its name or trade names to another business. The first must change its name or dissolve so the other can file for it.

When is a Colorado periodic report due?

Each year in the entity's reporting month, shown as the Periodic report month on its Summary page. It can be filed two months before or two months after that month without penalty.
