An AT&T Number Transfer PIN, short for Personal Identification Number, is a unique code required to authorize the transfer of a phone number from one carrier to AT&T. For example, if you’re switching from Verizon to AT&T and want to keep your old phone number, you’ll need to request a Number Transfer PIN from Verizon.
The Number Transfer PIN ensures that only the authorized account holder can transfer the phone number, preventing unauthorized access and protecting customer privacy. It’s a crucial step in the number portability process, which allows customers to switch carriers while retaining their existing phone numbers.
