How to Change Phone Number on iPhone

So you've decided that it’s time to change your phone number, whether it’s to avoid prank calls, to leave behind an old relationship, or anything else. Your phone number either comes from the SIM card (iPhone 13 or earlier) or an eSIM that’s completely digital. We’ll cover how to change your phone number and everything else you need to know.

How to Change My Phone Number with a Cell Phone Carrier

The only real way to get a new phone number and change the number associated with your iPhone is by contacting your current cell phone carrier or a new carrier that you want to switch to. Typically, when you switch cellular service providers, your new carrier will allow you to get a new phone number free of charge. This method of switching phone numbers is great if you are already considering switching carriers. Most carriers have done away with two-year contracts, so switching should not be an issue.

If you have an iPhone 13 or earlier, this may involve replacing your physical SIM card. Newer iPhones have eSIMs that can be replaced digitally. Your carrier will walk you through the steps on the phone or help you with this in person, which can be easier if you prefer. If you don't want to get a new number but simply need to transfer your phone number to another phone, the process for transferring your number is a little different.

Keep in mind that the process is different for each carrier, and you could be charged a fee, so make sure to research your carrier's policies on changing phone numbers. If you are dealing with a new eSIM phone number, you may be asked for your serial number (also called an IMEI); here's how to find it. Now you know how to change your number!
