What is necessary to get ATT Wireless to update CNAM.

We are here to help you change the Caller ID name to your phone number, @sunergysolutions.

We do understand how important it is to have the correct Caller ID name listed. We have some steps to take to change your display name.

1. Go to your myAT&T Profile and select People & permissions.
2. Select Show details for the number you want to update on Caller ID.
3. Choose Edit for Caller ID.
4. Enter the info and select Save.

Please note:

• You may have to sign out and sign back in to see the new name displayed online.
• The Caller ID name displays on phones that have Caller ID. It doesn’t override a name saved in a wireless device.
• It can take up to 72 business hours for caller IDs to show an updated Caller ID name.
• People may need to clear your number from their Caller ID record for your new name to appear.
• Some home phone service providers may not offer Caller ID or get regular updates to their Caller ID info.
• For AT&T PREPAID, the Caller ID name says Wireless Caller.

Try this and let us know how it goes!

This is not relevant to the detailed problem I posted. I'm not looking to update my CNAM/CallerID for my phone. I am trying to get ATT to update the national CNAM registry that ATT uses that shows the incorrect CNAM for a phone number that is not owned by ATT. Every other provider shows the correct callerID. ATT does not. The CNAM for 844-427-6527 was modified over 6 months ago.

Thank you for the response, @sunergysolutions.

Let's meet in a DM to further assist. You will find a chat icon next to a bell icon in the upper right corner of this page. Our next message will appear there.
