Have EIN but using dba for website and RingCentral. How can I register for TCA under dba?

As part of the registration process you will be prompted for the legal name of business as filed with the IRS (or federal tax agency if outside of the US), the EIN of the business, and the DBA or name of the brand. This will allow you to utilize your official EIN, while also helping carriers understand that you do operate with a DBA, and that your messages will be using a business name different from the name of your legal entity.

Additional details on how to register can be found in this instructional video or on our support site's step by step instructions.
