How can I update CNAM base for a non ATT number

Hello @cozysdad,

Thank you for reaching out to us. We understand your concern regarding the CNAM update, let's get the help you need.

 Updating the CNAM (Caller ID Name) for a non-AT&T number involves ensuring that the correct information is published in the relevant databases. Here are some steps you can take:

Check with Your Provider:
Contact your phone service provider (the one associated with the non-AT&T number) and ask them to verify that they are publishing the correct CNAM information to the relevant databases.
Make sure they have the accurate caller ID name associated with your number.

Third-Party Platforms:
Some third-party platforms can help update CNAM information. For example:
Hiya: You can submit a caller ID update request through the Hiya app or directly through your phone carrier1.
Free Caller Registry: This consortium of major providers simplifies the process of updating CNAM information2.
Other Services: Check if your provider uses services like HIYA, First Orion, or TNS for CNAM updates.

Be Patient:
CNAM updates may take time. Most providers suggest allowing 4-6 weeks for the changes to propagate2.
Remember that when your call passes through the AT&T network, AT&T may override the caller ID set by you. To ensure that AT&T has the correct CNAM in their LIDB (Line Information Database), follow the steps above and work with your provider to update the information. If you encounter any challenges, consider reaching out to AT&T directly for assistance.

Please feel free to reach us if you have any other questions.
