Registering a Trade/DBA (Doing Business As) Name

Registering a Trade/DBA (Doing Business As) Name

The registration of a trade name (sometimes referred to as a “business name,” “fictitious name” or a “DBA” short for "Doing Business As") is not legally required in Arizona but is a recommended business practice.

Note: If you are filing as a corporation or LLC with the Arizona Corporation Commission, it is not necessary to register your corporate name as a trade name with the Arizona Secretary of State’s office as names are cross-referenced with the Corporation Commission. (24)
