You can switch providers while keeping your phone number, but the process takes a few days and requires you to act in a specific order

Changing cell phone providers means moving your account from one company (like Verizon, AT&T, or T-Mobile) to another. The key thing to know is that you can keep your existing phone number when you switch — this is called number portability — but you have to request it before you cancel your old account. If you cancel first and then try to port the number, it may be lost permanently after 30 days.

The entire process usually takes three to five business days. During that time, you may have a gap where your old service stops but your new service hasn't fully activated yet. Planning ahead and understanding the order of steps prevents you from being without a phone when you need one.

Key Takeaways

  • Request a porting authorization code (also called a PIN or transfer code) from your current provider before you cancel — this is the document that lets the new provider move your number.
  • Your old provider may charge an early termination fee if you are still under contract, so check your bill or account online to see what you owe.
  • The new provider will handle most of the transfer, but you must give them your porting code and confirm your identity with your old provider's account details.
  • Keep your old phone active until the new provider confirms your number has transferred, because calls and texts may still route to the old account for a day or two.
  • If you own your phone outright, you can use it with the new provider if it is compatible with their network; if you financed it through your old provider, you may need to pay it off first.

What you need before you start

Gather these items before you contact your new provider. You will need your current account number (on your bill or in your provider's app), your PIN or password for that account, and the phone number you want to port. You should also know whether you are under contract with your current provider and what the early termination fee is, if one exists.

Check whether your phone is paid off. If you financed it through your current provider, you may owe a balance. Some providers will not let you port your number until the phone is paid in full; others will let you transfer the number but keep you on the hook for the remaining balance. Call your current provider's customer service line and ask directly: "If I switch providers, do I need to pay off my phone first, or can I port my number while still paying it off?"

Getting the porting authorization code from your current provider

Contact your current provider by phone, online chat, or in person at a store and ask for a porting authorization code. Different companies call this different things — Verizon calls it a "Wireless Number Transfer PIN," AT&T calls it a "transfer PIN," and T-Mobile calls it a "porting authorization code" — but they all do the same thing. Write down the code exactly as they give it to you, including any dashes or special characters.

The provider will ask you to confirm your identity by answering security questions or providing your account PIN. They may also ask why you are leaving. You do not have to explain; you can straightforward say you are switching to another provider. Some providers will offer you a discount to stay — you can accept or decline, but either way, get the porting code before you end the call. The code is usually valid for 30 days.

Do not cancel your account yet. This is the most common mistake. If you cancel first, your number goes into a holding period and may be reassigned to someone else before the new provider can port it.

Signing up with the new provider

Visit the new provider's website, call their customer service line, or go to a store. Tell them you want to switch and that you are bringing your existing phone number. They will ask for your porting authorization code, your current account number, and your phone number. Have all three ready.

The new provider will also ask what phone you want to use. If you own your phone outright (it is fully paid off), you can bring it with you if it is compatible with the new provider's network. You can check compatibility on the new provider's website by entering your phone's model number. If your phone is not compatible or you want a new one, the new provider will offer you phones to buy or finance.

The new provider will give you an set up date — usually within one to three business days. They will also give you a confirmation number. Write this down. You may need it if something goes wrong during the transfer.

What happens during the transfer

Once you have signed up with the new provider, they submit your porting request to your old provider. Your old provider has up to one business day to approve or deny the request. Most requests are approved automatically. If there is a problem — for example, if the account information does not match or if the porting code is wrong — your old provider will contact you.

During this time, keep your old phone turned on and active. Calls and text messages may still route to your old account for a day or two, even after your new service is supposed to be active. This is normal. Once the transfer is complete, your old account will close automatically (or you can call and close it yourself if you want to be sure).

When the transfer is complete, your new provider will send you a text or email confirming that your number has been ported. At that point, your old service will stop working, and your new service will take over completely. This usually happens overnight.

Early termination fees and what you might owe

If you are still under contract with your current provider, they may charge an early termination fee — typically $100 to $350, depending on how much time is left on your contract. Check your bill or log into your account online to see if you have a contract and what the fee is.

Some providers will waive the fee if you have been a customer for a certain length of time or if you are switching because of poor service in your area. It never hurts to ask, but do not count on it. Budget for the fee if it applies to you. The fee is separate from any balance you owe on a financed phone.

If something goes wrong

If your number does not port after five business days, contact your new provider's customer service when ready. Have your confirmation number ready. The most common problems are a typo in the porting code, a mismatch between the account information you provided and what is on file with your old provider, or a hold placed on your account by your old provider (usually because of an unpaid bill).

If your old provider placed a hold, you will need to pay the outstanding balance before the port can complete. If there was a typo, the new provider can usually resubmit the request with the correct information. If the account information does not match, you may need to call your old provider directly to confirm the details they have on file.

In rare cases, if your old provider denies the port, you have the right to file a complaint with the Federal Communications Commission (FCC). You can do this online at fcc.gov. The FCC can investigate and force the port to go through if your old provider is breaking the rules.

Frequently Asked Questions

Can I keep my phone number if I switch providers?

Yes. You can port your number to any other provider in the United States as long as you request the porting authorization code before you cancel your old account. The process takes three to five business days. If you cancel first without requesting the code, your number may be lost after 30 days.

Do I have to buy a new phone when I switch?

No. If your current phone is paid off and compatible with the new provider's network, you can bring it with you. Check the new provider's website to see if your phone model is compatible. If you want a new phone, the new provider will offer options to buy or finance.

What if I still owe money on my phone?

Some providers require you to pay off the phone before porting your number; others let you port while still paying it off. Call your current provider and ask directly. If you owe money, budget for that cost in addition to any early termination fee you might owe on your service contract.

Will I lose service while I'm switching?

You may have a gap of a few hours to a day where your old service has stopped but your new service is not fully active yet. To minimize this, do not cancel your old account until your new provider confirms the port is complete. Keep your old phone on during the transfer.

What is an early termination fee?

An early termination fee is a charge from your current provider if you cancel before your contract ends. It typically ranges from $100 to $350. Check your bill or account online to see if you have a contract and what the fee would be. Some providers may waive it if you ask, but there is no may provide.
