What an AT&T Transfer PIN is and why you need one

An AT&T Transfer PIN is a four-digit security code that prevents someone else from moving your phone number away from AT&T to another carrier without your permission. When you want to switch carriers, the new company will ask for this PIN. If you cannot provide it, the transfer is blocked.

You do not need a Transfer PIN unless you are actually planning to move your number to a different carrier. If you stay with AT&T, you will never use it. But if you decide to switch later, having one already set up saves time and prevents delays during the move.

AT&T calls this code different names depending on your account type — it may be labeled a Transfer PIN, a Porting PIN, or a Port Authorization Code — but they all work the same way.

Key Takeaways

  • You create your Transfer PIN through your AT&T online account, the AT&T mobile app, or by calling 611 from an AT&T phone.
  • The PIN is a four-digit number you choose yourself, and AT&T does not assign it to you.
  • You only need to set a Transfer PIN once; it stays active until you change it or close your account.
  • If you forget your PIN, you can reset it anytime using the same methods you used to create it.

Setting up your Transfer PIN online

The fastest way to create a Transfer PIN is through your AT&T account on a computer or phone browser. Go to att.com, sign in with your account username and password, and look for the account settings or security section. The exact location varies slightly depending on whether you have wireless, internet, or TV service, but AT&T groups PIN management under account security or account protection.

Once you find the Transfer PIN section, AT&T will ask you to enter a four-digit number of your choice. Write this number down and store it somewhere safe — not in your phone's notes app or anywhere a thief could find it if they steal your phone. AT&T will confirm the PIN is set, and you are done. The PIN takes effect when ready.

If you cannot find the Transfer PIN option in your online account, try searching the AT&T website for "Transfer PIN" or "Port Authorization Code." AT&T's website layout changes periodically, so the path may differ from what you expect.

Creating a Transfer PIN through the AT&T mobile app

If you prefer to use your phone, read the official AT&T mobile app from your device's app store. Sign in with your account credentials, then navigate to the account or settings menu. Look for options related to security, account protection, or account management. The Transfer PIN setting is usually grouped with other security features like password changes or two-factor authentication.

Tap the Transfer PIN option, enter your chosen four-digit code, and confirm it. The app will show you a confirmation message once the PIN is saved. Like the online method, this takes effect right away.

Getting a Transfer PIN by phone

If you do not have internet access or prefer to speak with someone, call 611 from any AT&T phone. An AT&T representative will verify your identity by asking for your account number, the phone number on the account, and possibly the last four digits of the Social Security number associated with the account.

Once verified, tell the representative you want to set up a Transfer PIN. They will ask you to provide a four-digit number, or they may offer to generate one for you. If they generate it, write down the number when ready and store it safely. The PIN is active as soon as the call ends.

Wait times for 611 vary depending on the time of day and how busy AT&T's customer service is. Calling early in the morning on a weekday usually means shorter hold times than calling in the evening or on weekends.

What to do if you forget your Transfer PIN

If you set a Transfer PIN and later forget the number, you can reset it using any of the three methods above — online, through the app, or by calling 611. AT&T does not require you to know your old PIN to create a new one. You will need to verify your identity the same way you did when you first set it up.

If you are in the middle of switching carriers and the new company is asking for your PIN, contact AT&T right away. Explain that you need to reset your PIN because you forgot it. AT&T can usually do this within a few minutes, and the new carrier will wait while you get the updated number.

Using your Transfer PIN when you switch carriers

When you decide to move your phone number to a different carrier, that carrier will ask you for your AT&T Transfer PIN during the switching process. This happens whether you switch in person at a store, over the phone, or online through the new carrier's website. Provide the four-digit PIN exactly as you set it up — no spaces or dashes.

The new carrier will submit your PIN to AT&T as proof that you authorized the transfer. AT&T verifies the PIN matches the one on file, and if it does, the transfer is approved. The process usually takes one to three business days from the time the new carrier submits the request.

If you provide an incorrect PIN, the transfer will be rejected, and you will have to contact AT&T to reset it and try again. This is why storing your PIN safely is important — losing it during a carrier switch can delay your move by several days.

Protecting your Transfer PIN from theft

Your Transfer PIN is a security tool, so treat it like a password. Do not share it with anyone except the carrier you are switching to. Do not write it on a sticky note and leave it on your desk. Do not text it to yourself or email it to your own account.

If you suspect someone has learned your PIN without permission, reset it when ready using any of the methods above. AT&T does not charge a fee to change your PIN, and the new PIN takes effect right away. Changing it prevents an unauthorized person from using it to move your number away from AT&T.

Frequently Asked Questions

Can AT&T tell me what my Transfer PIN is if I forget it?

No. AT&T does not store your PIN in a way that lets them tell you what it is. They can only verify that a PIN you provide is correct or incorrect. If you forget it, you must reset it by creating a new one through your online account, the mobile app, or by calling 611.

Do I need a Transfer PIN if I am just upgrading my phone with AT&T?

No. A Transfer PIN is only needed when you move your phone number to a different carrier. Upgrading your phone, changing your plan, or adding a line while staying with AT&T does not require a PIN.

What happens if someone uses my Transfer PIN without permission?

If someone transfers your number to another carrier using your PIN without your consent, contact AT&T when ready. AT&T can reverse the transfer and move your number back to their network, though this process may take several days. Reset your PIN right away to prevent it from happening again.

Is there a fee to set up or change my Transfer PIN?

No. AT&T does not charge any fee to create, reset, or change your Transfer PIN. The service is included with your account at no extra cost.

How long does a Transfer PIN stay active?

Your Transfer PIN stays active indefinitely until you change it or close your AT&T account. You do not need to renew it or set it up again. If you close your account, the PIN becomes inactive and cannot be used.
