Toll-Free Number verification

Toll-Free Numbers (TFN) now require verification for all SMS-related terminations. This industry-wide requirement helps combat spam and foster a more trusted messaging ecosystem through stronger verification and message filtering.

Verify TFN in the US Sender Registration app

To start the verification process, create or update a TFN brand in the US Sender Registration app. Make sure that you provide all the required information, including the correct contact details.

When your TFN brand is created:

1. Create a TFN campaign. The campaign then transitions to a Submitted for Review status. Infobip reviews the brand and campaign for compliance with US messaging content standards.
2. When the campaign validates successfully, your TFN transitions to a Submitted to Carrier status, ready to go through additional reviews.
3. Once all reviews are complete, the campaign transition into a Registered status.

You can also manage and track rejections and appeals through the US Sender Registration app.

Verify TFN over API

To verify Toll-Free Numbers over API, use the USA Number Registration API.

For more information, see the USA Number Registration API reference (opens in a new tab).

Check your TFN verification status

To check whether your Toll-Free Number is verified:

1. Go to the Numbers app.
2. Search for your specific Toll-Free Number.
3. Hover over the exclamation point next to your number.
   • If it displays TFN Verified, you are all set.
   • If the number is not displaying this status, ensure that the brand and campaign were submitted through the US Sender Registration app for verification.

For any TFN not appearing in the the Numbers app or that has not yet been submitted, completing the required brand and campaign setup in the US Sender Registration app.
