Find Your AT&T Account Number & Number Transfer PIN – Step-by-Step Guide
Switching carriers? Here's how to locate the two most crucial items for your porting process with AT&T—your account number and the Number Transfer PIN.
Locating Your Account Number
📋 Where to Find It
- Log into your myAT&T account via web or app
- Go to Account > Overview; you'll see "Account Number"
- Alternatively, check your recent bill (it appears near the top)
- Note: For legacy landline or U-Verse accounts the format may differ
Generating the Number Transfer PIN
1
From your AT&T mobile line
Dial *PORT (or *7678) and follow instructions
2
Or use myAT&T
Go to myAT&T > Profile > People & Permissions > Transfer Phone Number (for accounts with multiple lines)
3
Receive your PIN
After verification you'll receive a text with the 6-digit PIN
4
Use it quickly
The PIN is valid only for a short window—often 4–7 days. Use it before it expires
💡 Tips & Considerations
- Every wireless line under a shared account uses the same account number and same PIN
- Prepaid and business accounts may have different rules—check with AT&T if your account type is not standard
- Do not cancel your AT&T service before porting; the number must remain active during the transfer process
Frequently Asked Questions
What if I don't get the PIN text?
Try generating it again via *PORT, or contact AT&T support for manual assist.
How long does the PIN stay valid?
Typically about 4 days.
Can I use the PIN for multiple numbers under the same account?
Yes—if all numbers use the same account, a single PIN generally works.
