How to find your iPhone’s Serial Number, IMEI, UDID and more

How to find your iPhone's important information.

You sometimes need your iPhone’s or iPad’s serial number, IMEI or UDID when you are thinking of selling it and want an appraisal, you need to claim insurance or for any other reason. Before we jump into where to find them, let’s see what these numbers are:

iPhone and iPad IMEI

Also known as the International Mobile Equipment Identify number, the IMEI is yet another unique ID number for your device. It’s used by carriers to identify valid devices on their network. You might need this number if your phone was stolen and you want to stop it from being used.

iPhone and iPad Model Identifier

This is a number, not unique to your iPhone or iPad, that simply identifies the model of device you have. For instance, if you have an iPhone 7 Plus, your model identifier will be iPhone9,4.

iPhone and iPad UDID

Your Unique Device Identifier or UDID is another number unique to your physical device used for identification purposes. Developers often use UDIDs when registering devices with the Apple Developer Program for use in development. This ID is also used by iTunes to detect the phone or to communicate with it while restoring the iPSW firmware. This unique ID cannot be changed by the user nor Apple, but changing the motherboard will change said ID.

iPhone and iPad Serial Number

This is a number unique to your iPhone or iPad that can be used to identify your device. Apple or your carrier will often ask for your serial number when providing support for your device, and you’ll also need your serial number if you’re looking to make a trade in.
