Port numbers
Porting means moving your existing phone number from one carrier
(e.g., Verizon, T-Mobile) to another (e.g., AT&T).
Here's how it works
1
Check Eligibility
Make sure your number can be ported (almost all can).2
Gather Info
Your current account number (from old carrier).The account PIN or port-out PIN (your old carrier provides it).The billing address and name on your current account.3
Start Port Request
When you sign up with AT&T, you give them this info, and AT&T requests the number from your old carrier.4
Wait for Transfer
Usually takes a few minutes to a few hours, sometimes up to 1–2 days.5
Activation
Once complete, your AT&T SIM/eSIM works with your old number. How Port-In Credits Work
AT&T often give credits if you bring a number from another provider.
Here's how it works
1
You port in your number following the steps above.
2
AT&T confirms it’s a valid port (not from an AT&T-owned company like Cricket or FirstNet, since those often don’t qualify).
3
The credit is usually applied as bill credits over a period (like $6.94/month for 36 months = $250 total).
4
If you cancel early, you lose the remaining credits.
If no Port-In Credit
Sometimes porting is just required for eligibility on certain
promotions, but there’s no separate port-in bonus.
Here's how it works
.
AT&T says “Get $1,000 off with trade-in when you port your number.”
.
In this case, the port itself doesn’t give you credit—it just makes you eligible for the trade-in promo.
.
If you don’t port, you may not qualify.
