What happens when you switch phone providers

Transferring your phone service means moving your existing phone number and account from one provider to another. The process is called a port, and it typically takes three to five business days. During that time, your old provider and new provider coordinate the transfer — you don't need to do much once you've started the request, but you do need to know what information to have ready and what to expect while the switch happens.

You can transfer a landline, a mobile number, or both. The steps are similar regardless of which type you're moving, though mobile transfers sometimes happen faster because the networks are set up to handle them constantly. If you're switching from a landline to mobile or vice versa, the port still works the same way — your number moves with you.

Key Takeaways

  • You need your account number and PIN or password from your current provider before you contact the new one, so gather those first.
  • The port takes three to five business days on average, and your service may drop briefly during the handoff — tell people you're switching so they know to reach you another way if needed.
  • Your new provider will contact your old provider to request the transfer; you don't need to call your old company yourself unless something goes wrong.
  • Early termination fees from your old provider are separate from the port process and may still explore depending on your contract.
  • Once the port completes, your old account closes and you'll receive a final bill from your previous provider.

Information you need before you start

Contact your current provider and ask for your account number and the phone number you want to port. Write both down exactly as they appear in your account. You'll also need a PIN or password — this is a security measure that proves you own the account. If you don't have a PIN set up, call your current provider and ask them to create one before you request the port.

Some providers call this a "port PIN" or "transfer PIN." It's different from your voicemail PIN. Ask your current provider specifically which number or code you'll need to give to your new provider. Write it down and keep it safe until the port is complete.

If you're porting a business line, you may need additional documentation like a business license or proof of authorization to transfer the account. Ask your current provider what they require before you move forward.

How to request a port from your new provider

Contact your new provider by phone, online, or in person and tell them you want to port your number. They'll ask for your current account number, the phone number you're porting, and your PIN or password. Have all three pieces of information ready when you call or start the online process.

Your new provider will submit the port request to your old provider on your behalf. You do not need to contact your old provider yourself — the two companies handle the coordination. Your new provider will give you a confirmation number and an estimated completion date. Write down the confirmation number and keep it until the port is finished.

Some providers charge a porting fee, usually between $15 and $30. Ask your new provider about this before you confirm the request. The fee appears on your first bill with them.

What to expect during the three to five day wait

Your old provider has a window of time to approve or reject the port request. Most approvals happen within one business day, but the full process can take up to five. During this time, your service with your old provider continues to work normally.

On the day the port completes, your service may drop for a few minutes or a few hours while the networks switch over. This is normal. Your new provider's service should set up automatically once the port is done. If you don't have service after a few hours, contact your new provider and give them your confirmation number.

Your old provider will send you a final bill for any remaining balance or prorated charges. This bill is separate from the port process and arrives after the transfer is complete. If you had a contract with your old provider, any early termination fees appear on this final bill.

What happens if the port is rejected

A port can be rejected if your account number or PIN is incorrect, if there's a dispute about who owns the account, or if your old provider has a hold on the account for unpaid bills. Your new provider will contact you with the reason for the rejection and ask you to fix the problem.

If the issue is a wrong account number or PIN, contact your old provider to get the correct information and resubmit the request. If the issue is unpaid bills or a dispute, you'll need to resolve that with your old provider before the port can go through. Once the problem is fixed, your new provider can resubmit the request.

Porting a number you've had for many years

If your phone number is very old or was transferred between providers multiple times in the past, the port may take longer or require extra steps. Some older numbers have incomplete records in the system, and your old provider may need time to locate the full account history.

If you run into delays, ask your old provider whether there are any blocks or flags on the account that might slow down the transfer. Sometimes a very old account needs to be updated in the system before it can be ported. This usually takes a few extra days but doesn't prevent the port from happening.

Keeping your number if you're switching phone types

You can port a landline number to a mobile provider and keep the same number on your phone. You can also port a mobile number to a landline or to a different mobile provider. The port process is identical — your new provider requests the transfer, and your old provider releases the number.

The only limitation is that some very old landline numbers cannot be ported to mobile, though this is rare. If your new provider tells you your number cannot be ported, ask them why and whether there's an exception process. Most numbers can move between service types without any problem.

Frequently Asked Questions

Can I use my phone while the port is happening?

Yes, your old service continues to work until the port completes. You may lose service briefly on the day the transfer finishes, usually for a few minutes to a few hours. Once your new provider's service activates, you'll have full service again.

Do I have to pay an early termination fee if I port my number?

Early termination fees are separate from the port process. If you're under contract with your old provider, they may charge a fee when you leave — this appears on your final bill. The port itself doesn't trigger the fee; your decision to stop service does. Check your contract or call your old provider to find out whether a fee applies to you.

What if my new provider doesn't have service in my area?

You should confirm coverage before you request the port. Check your new provider's coverage map for your address. If they don't have service where you need it, you can cancel the port request before it completes and stay with your old provider. Once the port finishes, your old account closes.

Can I port a number that's in someone else's name?

No. The person whose name is on the account must request the port or give written authorization. If you're trying to port a number that belongs to a family member or business partner, they need to be involved in the request. Your new provider will ask for proof of authorization if the account holder isn't the one making the request.

What if I change my mind after I request the port?

You can cancel the port request before it completes by contacting your new provider and asking them to withdraw the request. Once the port finishes and your old account closes, you cannot reverse it. If you want your old number back after a completed port, you'd have to request it from your old provider, and they may not be able to restore it.
