My local Att store

Exactly what issues are you trying to report?  If you have a phone that was reported stolen, it’s probably been blacklisted and can’t be used unless it gets removed from the blacklist.

Hello, @victorott,

Thanks for reaching out on this. We're sorry to hear your phone was stolen. You can sign into your myAT&T account to report the device as stolen and suspend service on it. You would follow these steps:

1. Sign into your myAT&T account.
2. Go to https://soc.att.com/37p2nUY .
3. Choose a reason and select Suspend.
4. Follow the prompts to suspend service and block the device.

Yes, your local AT&T Store should be able to assist if you can't do it online or would rather not do so.

Have a great week.

James, AT&T Community Specialist
