Do I need a DBA in Oklahoma?
Oklahoma does not require that sole proprietorships, general partnerships, corporations, limited liability companies (LLCs), limited partnerships (LPs), limited liability partnerships (LLPs), or out-of-state companies that regularly transact business in Oklahoma under a name different from their legal name, to file a DBA with the Oklahoma Secretary of State. Having said that, you can benefit from filing a DBA in Oklahoma because it will make it easier to bank in Oklahoma, will let you register a desired name before a competitor registers it, and can help you avoid trademark infringement.
