What is MEID? Meaning, Number Format, and eSIM Compatibility(2026)
When you see "MEID" in your phone settings or after dialing *#06#, you might wonder: What is MEID? Can it be used to tell if my phone supports eSIM? This guide provides a complete breakdown of the MEID meaning, formats (Hex/Dec), lookup methods, and its real relationship with eSIM activation.
MEID (Mobile Equipment Identifier) is a hardware identification number for CDMA mobile devices. It CANNOT be used to activate or determine eSIM compatibility! To confirm if your phone supports eSIM, check if an EID is displayed on your screen (or if you have an option to add an eSIM in settings).

1. What is MEID? What is the Purpose of a MEID Number?
MEID (Mobile Equipment Identifier) is a globally unique 56-bit hardware identifier specifically used to identify physical mobile devices on CDMA network architectures. You can think of it as the "ID card number" for CDMA mobile phones.
Primary Uses of MEID:
- Carrier Device Authentication: Mobile carriers (such as traditional Verizon, Sprint, etc.) use MEID to identify legitimate devices and grant network access.
- Stolen Phone & Blacklist Tracking: If a device is lost or stolen, carriers can place its MEID on a blacklist to prevent it from operating on CDMA networks.
- Warranty & Repairs: Manufacturers and service centers use MEID to verify production batches and active warranty coverage.
MEID Formats: Hexadecimal (Hex) vs Decimal (Dec)
When looking up your MEID, you may see two different formats:
- MEID Hex (Hexadecimal): Usually consists of a 14-character string of numbers and letters (A-F) (e.g.,
35693803564102orA1000012B34C5D). - MEID Dec (Decimal): A 18-digit numeric-only format converted from Hex, used by some legacy carrier systems for manual registration.
MEID vs ESN: The Evolution of Cellular IDs
In the early days of 2G/3G CDMA networks, mobile phones utilized 32-bit ESN (Electronic Serial Number) identifiers. As the global number of mobile devices exploded, the ESN pool faced exhaustion around 2006, leading the telecommunications industry to introduce the 56-bit MEID to fully replace ESN.
2. MEID for eSIM: Can MEID Be Used to Check or Activate eSIM?
Many users notice MEID in their phone settings before purchasing travel eSIMs and wonder: "I have a MEID number, does that mean my device supports eSIM?" The answer is NO.
MEID is simply a hardware identifier for physical SIM chips and CDMA networks. eSIM operation relies entirely on whether your phone contains an eUICC (Embedded SIM chip), whose identifier is called EID (eUICC ID).
Why Can't MEID Be Used for eSIM Activation?
- Different Technical Standards: MEID was designed for 2G/3G/4G carrier hardware authentication, whereas eSIM profile downloads and binding depend entirely on the 32-digit EID.
- Having MEID Doesn't Mean You Have eUICC: Many older CDMA phones that do not support eSIM still feature a MEID, so MEID cannot serve as a criteria for eSIM support.

3. How to Find Your MEID Number? (iPhone & Android Guide)
If you need to check your phone's MEID for customer service or warranty verification, here are the two fastest methods:
Method 1: Universal Dial Code (Fastest)
Open your phone's Dialer/Phone app and enter:
*#06#
A pop-up window showing IMEI, MEID, and EID details will instantly appear on screen.
Method 2: iOS / Android System Settings
- iPhone (MEID Check iPhone): Go to "Settings" > "General" > "About", and scroll down to find the MEID field.
- Android Phones: Go to "Settings" > "About Phone" > "Status Information" or "SIM Status" to view your MEID/IMEI numbers.
(Tip: To verify eSIM support on the *#06# screen, look for the EID barcode as shown in the image above.)

4. Frequently Asked Questions FAQ | MEID & eSIM Solutions
Q1: What is a MEID number used for?
MEID is primarily used by CDMA carriers to identify mobile devices, verify device legitimacy, track lost/stolen phones, and register hardware warranties with manufacturers.
Q2: Can MEID be used to activate an eSIM?
No. eSIM activation and profile provisioning rely exclusively on the EID (eUICC ID). MEID cannot be used for any eSIM setup or service provisioning.
Q3: What is MEID on iPhone?
MEID on an iPhone is the hardware identifier retained by Apple for models supporting CDMA networks (such as global models). On newer iPhone models, it often shares hardware info with IMEI 1.
Q4: How do I convert between MEID Hex and Dec formats?
Hex is hexadecimal (containing letters A-F) while Dec is decimal (digits only). Most users do not need to convert this manually; if a carrier requires a specific format, standard online MEID Converter tools can be used.
Q5: Dialing *#06# only shows IMEI and no MEID. Does it matter?
Not at all. Modern 5G and 4G networks have fully transitioned to GSM/LTE/5G standards. Many newer smartphones no longer display MEID—you only need to focus on IMEI and EID.
