How to verify your business for caller ID and spam protection

Verifying your business with the carriers unlocks your caller ID name, signs your calls so people are less likely to see "Spam Likely", and is the first step to texting. This guide shows account admins how to see where each line stands, choose a business's lines, fill in the legal details, address, and authorized representative, send it for verification, and add a second business to the same account.

Questions and answers

How long does verification take?

Usually a few business days. The status is checked every hour and shows not started, being reviewed, needs a fix, or verified.

What does verification unlock?

Your lines' caller ID name is filed with the carriers, every number is signed so calls get the highest trust level (SHAKEN/STIR "A" attestation), and texting registration can go ahead.

We run two companies. Can they share one account?

Yes. Add each business with its own legal details and choose which lines belong to it. One plan, one bill, and one team cover both.

Can a line move to another business?

Only before its number is filed with the carriers. After that it stays with its business.

I'm a sole proprietor without an EIN. Can I still verify?

Yes. Choose that you're a sole proprietor without an EIN and fill in your own details.
