How to find an iPhone’s ECID

Depending on what you’re doing with your iPhone or iPad, a time may come when you need to find your device’s Exclusive Chip Identifier, otherwise more recognizably abbreviated as the ECID.

The process of finding your handset’s ECID will be different depending on whether you have a Mac or a Windows PC. In today’s tutorial, we’ll show you how to find it in either of those scenarios.

Why you may need to know your ECID

Most ordinary iPhone users will never need to know their ECID, but if you ever choose to dabble with non-traditional firmware downgrades, make use of SHSH blobs, or use signing status apps like MobileTSS, then the ECID something you may need to find and/or make use of in the future.

The Exclusive Chip Identifier (ECID) is exactly what it sounds like – a special code used to identify the chip inside of your device. No two ECIDs are alike. The ECID is not the same as the UDID, the latter of which instead stands for Unique Device Identifier.

If you need help finding out what your device’s ECID is, then you can follow the macOS and Windows-based steps that are separately outlined below.
