If a number you purchased from Twilio is now gone, please double-check that you have the correct Account SID and login to view your numbers in the Twilio Console.
There are two common reasons for why a number you bought is no longer available:
1) The number was deleted
It’s possible you or a colleague accidentally deleted this number from your account, either by clicking “Release” on the number’s page or by performing a DELETE request to the phone numbers API.
2) The number was reclaimed
On occasion, Twilio may take back phone numbers that do not have enough traffic or belong to suspended projects. This is so we can comply with regulatory requirements.
Regulators and carriers in many countries discourage keeping phone numbers without using them. Phone numbers are a limited resource, and are the mechanisms for traffic. Adding new area codes, prefixes, and overlays is costly and difficult. So, regulators advise carriers on the minimum traffic their phone numbers should receive. You can find more details about reclaimed numbers in our Terms of Service.
You can always reach out to support if you’re unsure why a given number is missing.
1) Restore recently deleted numbers
If the number was released in the last ten (10) days, you can visit the Console to restore a deleted number.
2) Use your existing numbers
It's always best to use the phone numbers you have, or release them so others can use them. As a last resort, we'll reclaim unused numbers.
