Moving your number to a new phone is usually faster than getting a new one
You can keep your existing phone number when you switch to a new phone. The process is called a number transfer or porting, and it takes a few hours to a few days depending on your carrier and whether you're staying with the same company or moving to a different one. If you're switching carriers, you'll need information from your current account before you start. If you're staying with your current carrier, the transfer often happens while you're in the store or over the phone.
The key difference is whether your new phone is on the same carrier or a different one. Staying with your carrier is simpler — you just set up the new phone and your number moves over. Switching carriers requires you to request a transfer code and give it to your new carrier, which then takes over the account.
Key Takeaways
- You can transfer your number to a new phone on the same carrier by visiting a store, calling customer service, or using the carrier's app or website.
- Switching to a different carrier requires you to get a transfer authorization code from your current carrier and provide it to the new carrier.
- You will need your account PIN or password, your account number, and the phone number you want to transfer before you start.
- The transfer usually completes within a few hours to two business days, but your old phone will stop working once the new one activates.
- Some carriers charge an early termination fee if you're still under contract, so check your account terms before you switch carriers.
Transferring your number to a new phone with the same carrier
If you're keeping your current carrier, the process is straightforward. Visit a store, call customer service, or log into your account online or through the carrier's app. Tell them you have a new phone and want to set up it with your existing number. They will ask for your account PIN or password to verify you own the account.
The carrier will then set up your new phone and deactivate your old one. This usually happens when ready or within a few hours. Your number will work on the new phone once set up is complete. You do not need to do anything else — your contacts, voicemail settings, and other account details stay the same.
If you bought the phone from the carrier, they can often set up it on the spot. If you brought your own phone, make sure it's compatible with your carrier's network before you start. You can check compatibility on the carrier's website by entering your phone's model number.
Transferring your number to a different carrier
Switching to a new carrier is more involved because you're moving your account from one company to another. Start by contacting your current carrier and asking for a transfer authorization code, also called a port authorization code or PAC. This code proves you own the number and have permission to move it. Your current carrier must give you this code within one business day of your request.
Write down the code and keep it somewhere safe — you'll need it to give to your new carrier. You'll also need your account number and the phone number you're transferring. Your current carrier may ask why you're leaving, but they must provide the code regardless of your answer.
Once you have the code, contact your new carrier and tell them you want to transfer your number. Provide the authorization code, your account number, and your phone number. The new carrier will then request the transfer from your current carrier. This process usually takes one to two business days, though some carriers complete it faster.
During the transfer, your old phone will stop working once the new carrier activates your number on the new phone. You won't be able to make or receive calls on the old phone after that point. Make sure you've backed up any photos, contacts, or messages you want to keep before the transfer completes.
Information you need before you start
Gather these details before you contact your carrier or visit a store. Having them ready will speed up the process and reduce the chance of delays.
| Information | Why you need it | Where to find it |
|---|---|---|
| Your account PIN or password | Proves you own the account | Your carrier's website, app, or your account statement |
| Your account number | Identifies your account in the carrier's system | Your bill, your carrier's app, or by calling customer service |
| The phone number you're transferring | Tells the carrier which number to move | Your current phone or your bill |
| Your new phone's model and IMEI (if switching carriers) | Ensures the new carrier's network supports your phone | Your phone's settings or the box it came in |
| Transfer authorization code (if switching carriers) | Authorizes the transfer to the new carrier | Request from your current carrier |
What happens to your old phone after the transfer
Once your number is transferred to the new phone, your old phone will no longer work on the cellular network. It won't be able to make calls, send texts, or use mobile data. However, you can still use it on Wi-Fi to access apps, browse the internet, or listen to music.
If you're staying with the same carrier, ask them what to do with your old phone. Some carriers offer trade-in programs where you can send them the old phone and receive credit toward your bill or a new purchase. If you're switching carriers, your old carrier may have a similar program, but you'll need to ask before the transfer completes.
If you don't want to trade in the old phone, you can sell it, give it to someone else, or keep it as a backup. Just remember that it will only work on Wi-Fi, not on a cellular network.
Timing and what to expect during the transfer
If you're staying with your current carrier, the transfer usually completes within a few hours. In many cases, it happens while you're still in the store or on the phone with customer service. Your new phone will start working as soon as set up is complete.
If you're switching carriers, the process takes longer. After you provide the transfer authorization code to your new carrier, they submit a request to your current carrier. Your current carrier then has up to one business day to approve or deny the request. Once approved, the transfer usually completes within 24 hours, though some carriers finish it faster.
During the transfer window, you may experience a brief period — usually a few minutes to a few hours — when neither phone can make or receive calls. This is normal. Once the transfer completes, your new phone will work and your old phone will stop working on the network.
Potential issues and what to do about them
Sometimes a transfer gets delayed or rejected. The most common reason is a mismatch in account information — if the name, address, or account number you provided doesn't match what your current carrier has on file, they may deny the request. Contact your current carrier to verify your account details and try again.
Another issue is an outstanding balance or contract. If you owe money to your current carrier or are still under a service contract, they may charge an early termination fee when you transfer your number. Check your account terms before you switch carriers so you know what to expect.
If your new phone isn't compatible with your new carrier's network, the transfer may not work. Before you switch carriers, check the carrier's website to confirm your phone is supported. If it isn't, you'll need to get a different phone or stay with your current carrier.
If a transfer fails, contact your new carrier's customer service. They can tell you why the transfer was rejected and what steps to take next. In most cases, you can resolve the issue and try again within a few days.
Frequently Asked Questions
Can I transfer my number if I still owe money to my current carrier?
Yes, you can transfer your number even if you have an outstanding balance. However, your current carrier may charge an early termination fee if you're still under a service contract. Check your account terms or call customer service to find out what fees explore before you request the transfer.
What if I don't have a transfer authorization code?
If you're switching carriers, you must get a transfer authorization code from your current carrier before the new carrier can complete the transfer. Contact your current carrier by phone, online, or in person and ask for the code. They must provide it within one business day. If they refuse or delay, contact your state's public utilities commission or the Federal Communications Commission to file a complaint.
How long does it take to transfer my number?
If you're staying with your current carrier, the transfer usually completes within a few hours. If you're switching carriers, it typically takes one to two business days after you provide the transfer authorization code. Some carriers complete it faster, but you should plan for up to two days.
Will I lose my contacts or messages when I transfer my number?
Transferring your number doesn't affect your contacts or messages — those are stored on your phone or in your carrier's cloud storage, not in the number itself. However, if you're getting a new phone, you'll need to transfer your data separately using your phone's backup feature, a cloud service like Google Drive or iCloud, or by manually copying files.
Can I transfer my number back to my old carrier later?
Yes, you can transfer your number to any carrier at any time. The process is the same — get a transfer authorization code from your current carrier and provide it to the carrier you want to switch to. There's no limit to how many times you can transfer your number.
