EID, ICCID, IMEI: Demystifying the World of Mobile Identity Numbers

26 March 2024

Ever wondered what those long numbers on your phone or SIM card mean? At eSIMdata.co, we deal with the world of eSIMs every day, and we understand that some technical terms can be confusing. So, let's break down three key identifiers you might encounter: EID, ICCID, and IMEI.

  • EID (Embedded Identity Document): This 32-digit number is unique to your eSIM chip. It's like a digital fingerprint that identifies your device to cellular networks. Unlike a physical SIM card, the EID is embedded directly into your phone or other device. This allows you to switch data plans easily without needing to swap any cards!

  • ICCID (Integrated Circuit Card Identifier): This 18 or 19-digit number is the traditional identifier for physical SIM cards. It acts like a serial number, keeping track of the specific SIM card and the information it stores. If you've ever activated a new SIM card, you've likely encountered the ICCID.

  • IMEI (International Mobile Equipment Identity): This 15-digit number is unique to your phone or mobile device itself, not the SIM card. It's like a permanent ID for your device, used by network providers to identify and track specific phones. This can be helpful in cases of loss or theft.

Here's a table to summarize the key differences:
