# Locating Account Numbers & Transfer PINs by US Carrier
To port a phone number in the US, a user typically needs to provide their **account number** and a **number transfer PIN** (sometimes called a port-out PIN) from their current (donor) carrier. Since these credentials are not always easy for users to find, we recommend surfacing carrier-specific instructions in your application. This page provides those instructions, organized by carrier.
For background on the overall porting process, see [Porting in the US][porting-in-the-us]. For the API workflow to submit a port, see [How Porting In Works][how-porting-in-works].

## Gigs Recommended Account Number Validation
To reduce carrier-side rejections, Gigs recommends implementing the following client-side validation on account number fields before submission.
| Carrier | Format | Length |
| --- | --- | --- |
| AT&T | Digits only | 6–13 characters |
| Verizon | Letters and numbers (no special characters) | 1–18 characters |
| Spectrum | Digits only | Exactly 10 characters |
| Cricket | Digits only | Exactly 9 characters |
| Metro by T-Mobile | Digits only | Exactly 9 characters |
| T-Mobile | Digits only | 7–15 characters |
**Notes:**
* Verizon prepaid account numbers may begin with a letter followed by digits (e.g. "A" + 11 digits). Alphanumeric input should be accepted.
* Verizon postpaid account numbers frequently begin with a leading zero — do not strip or block these.
* Account numbers are distinct from transfer PINs and billing PINs. Validation rules above apply to account number fields only.
