Before You Begin
📋 Pre-Porting Checklist
- Ensure your AT&T line is active and in good standing
- Gather your account number and the Number Transfer PIN
- Confirm that there are no hold or suspension flags on your account
- Keep your old SIM/device accessible until the port completes
Step-by-Step Porting
Request your Number Transfer PIN
- • Dial *PORT (or *7678) from the AT&T device, follow prompts to request the PIN via text
- • Alternatively, log into myAT&T > Profile > Transfer Phone Number to request
- • Note: This PIN is typically valid for a limited number of days (for example, four days) so plan accordingly
Provide details to new carrier
Give the new carrier your AT&T account number, transfer PIN, and your name/address as listed on AT&T account
Initiate the port
The new carrier submits the port-in request; AT&T releases the number
Wait for completion
Mobile numbers often port within hours to 1 business day; landlines or special services may take 2-5 business days or longer
Confirm & wrap up
Once the number is active on the new carrier, verify calls/texts work, then check your AT&T account to ensure final bill/invoice is handled
📱 What Happens to Your AT&T Service
- • Your AT&T line closes automatically once the number is ported
- • You'll receive a final invoice for any outstanding balance, device-payment plans, or prorated charges
- • Any AT&T-specific features (voicemail transcripts, AT&T Cloud, etc.) will stop once service ends
