How to Get Your AT&T Transfer PIN: Step-by-Step Guide

A transfer PIN (also called a mobile number transfer PIN or port PIN) is a security code that AT&T requires before you can move your phone number to another carrier. It's a short numeric code—typically four to six digits—that prevents unauthorized transfers of your account.

If you're planning to switch carriers while keeping your existing phone number, you'll need this PIN. Here's how to get it, what to expect, and what you should know before requesting one.

Why You Need a Transfer PIN 🔐

Before you can port your number to a new carrier, that carrier needs verification that you authorized the transfer. AT&T uses the transfer PIN as proof of ownership. Without it, the porting process will be delayed or denied.

The PIN is tied to your specific phone number and account, not your entire AT&T account. You can request one without affecting your current service.

How to Request Your Transfer PIN

Online (My AT&T Account)

  1. Log into your My AT&T account at att.com
  2. Navigate to Account or Settings (exact menu placement varies by account type)
  3. Look for an option labeled "Transfer PIN,""Port PIN," or "Mobile Verification Code"
  4. Select "Generate" or "Request Transfer PIN"
  5. Choose which phone number you're porting (if you have multiple)
  6. AT&T will display your PIN immediately; write it down or screenshot it
  7. Note the expiration date—PINs typically expire after 30 days

By Phone

Call AT&T customer service at 611 from your AT&T phone or 1-800-331-0500 from any phone:

  • Tell the representative you need a transfer PIN for your phone number
  • They'll verify your account information
  • You'll receive the PIN over the phone—request they email or text it to you as well for your records

In an AT&T Store

Visit a local AT&T retail location with a valid ID matching your account holder information. A representative can generate your PIN on the spot.

What Happens After You Get the PIN

Once you have the PIN, you're not committed to switching carriers. The PIN simply authorizes AT&T to release your number if another carrier requests it. Requesting a PIN doesn't start the porting process by itself.

When you're ready to switch:

  1. Contact your new carrier and provide your current phone number
  2. When asked, provide the transfer PIN you received from AT&T
  3. Your new carrier submits the porting request with your PIN to AT&T
  4. The transfer typically completes within 1–24 hours, though it can take longer in some cases
  5. Your service switches to the new carrier; AT&T service on that number ends

Important Things to Know

Expiration: Most transfer PINs expire 30 days after they're issued. If yours expires before you port your number, you'll need to request a new one.

Account status: You can usually request a transfer PIN even if your account is past due or suspended, though some situations may require the account to be in good standing. Check AT&T's current policy or contact support directly if your account has issues.

Multiple phone numbers: If you have more than one number on your AT&T account, request a separate PIN for each number you plan to port.

Prepaid vs. postpaid: The process is the same whether your account is prepaid or postpaid, though prepaid customers should verify their account dashboard includes the PIN option.

Timing: Don't request your PIN too far in advance. Since they expire, it's best to request one within a few days of actually switching carriers.

What You'll Need to Provide

When requesting your PIN by phone or in-store, have ready:

  • Your phone number
  • Your account PIN or last four digits of your Social Security Number (for verification)
  • Valid photo ID (for in-store requests)

Next Steps

Once you have your transfer PIN, you're prepared to port your number whenever you choose. Contact your new carrier to begin the porting process—they'll guide you through their side of the transfer and will ask for your PIN at that time.
