A UUID (Universally Unique Identifier) ​​is assigned on your Mac, iPhone and iPad. These codes are device-specific and, much like a serial number, are used by developers to identify each device individually. Here's what you need to know:

What is a UUID?

A UUID consists of a sequence of letters and numbers that form a unique pattern. Your Mac, iPhone and iPad each have a UUID, and no other device shares them. In this regard, it's similar to a serial number, but while Apple and your wireless service provider use serial numbers to identify your device, developers typically use the UUID instead.

Normally, you would not need to know (or access) your UUID. However, if you register a device as part of the Apple Developer Program to install the beta software, you will need it. App developers may also ask for your device's UUID so they can deploy builds that only work on that particular device.

Other identifiers to consider

There are a few other identifiers that you may also come across.

  • Model identifiers are used to highlight the model of a particular device. These are not specific to this device, but to the model group it falls into. For example, an iPhone 7 is referred to as iPhone 9, x, while an iPhone XS is referred to as iPhone 11, x. These numbers are typically used only by Apple, but sometimes they appear in relation to upcoming devices.
  • Apple and its suppliers use model numbers to identify devices and the market for which they were developed. For example, an iPhone XS sold in the US is A1920, while A2098 is sold in Japan.
  • IMEI numbers (International Mobile Equipment Identification Numbers) are used by network operators. They apply only to devices that connect to the mobile network and are often used to block devices that have been reported as stolen or lost.
