Keybase and Non-VoIP Numbers

Keybase ties phone numbers to devices and accounts, so a number that has been used before is likely to be rejected.

A fresh carrier line is the cleanest starting point, and the rental model gives you a number that has not been recycled through free SMS sites.

FAQ

Why was my number rejected?

It was probably already attached to another Keybase account or classified as VoIP.

Do I need a new number each time?

For a new account, yes — reuse is the fastest way to trigger a rejection.

Can I keep the same number for the whole flow?

Yes, the line stays active for the tier you bought.

What if the code does not arrive?

Retry after changing your network, then contact support with the order number.
