Multiply every second digit (the even-positioned digits) by 2.
A 32-bit identifier originally used for CDMA phones. It is typically presented as an 8-digit hexadecimal or 11-digit decimal number.
, you are essentially translating between different formats of a device's unique serial number. While they serve the same purpose—identifying mobile hardware—they use different numbering systems (Decimal vs. Hexadecimal) and lengths Core Differences & Conversion Logic ESN (CDMA): An older 11-digit decimal or 8-digit hex identifier MEID (CDMA/LTE): A 14-digit hex or 18-digit decimal number that replaced ESN IMEI (GSM/LTE): A 15-digit decimal identifier used globally The "Fixed" Rule: A common conversion "fix" is that an MEID is simply an IMEI without the last digit (the check digit)
The IMEI is a 15-digit number that identifies the device itself, distinct from the SIM card which identifies the subscriber. As the telecommunications landscape consolidated and technologies converged (CDMA carriers adopting SIM cards and LTE networks requiring IMSI/IMEI structures), the divide between the MEID and the IMEI became a logistical nightmare. esn dec meid converter to imei fixed
ESN, DEC, MEID, and IMEI Converters: How to Fix Device Identifier Errors
If you are building an internal database system, it is highly recommended to integrate an instead of relying on manual conversion scripts, as it ensures real-time compliance with GSMA standards.
By understanding the fundamental differences between these identifier formats, using reliable conversion tools, and following the troubleshooting tips outlined in this guide, you can successfully perform conversions and resolve the issues that sometimes accompany them. Whether you're activating a device on a new carrier, checking a phone's blacklist status, or repairing a device with corrupted identifiers, the ability to convert between ESN, MEID, DEC, and IMEI formats is an essential skill in the modern mobile ecosystem. Multiply every second digit (the even-positioned digits) by
MEID is actually compatible with IMEI since the first two digits of an MEID will always be >= 0xA0 (hexadecimal A0) while those digits in an IMEI will always be less than 0xA0. The conversion process involves:
A unique 32-bit binary number manufactured into wireless phones by the manufacturer. It is primarily used with CDMA networks. It can be represented as an 11-digit Decimal (DEC) number or an 8-digit Hexadecimal (HEX) number.
Find your ESN Decimal (11 digits), MEID Hex (14 characters), or MEID Decimal (15 digits). , you are essentially translating between different formats

Here's a simplified Python implementation of an ESN/MEID to IMEI converter:
The Electronic Serial Number (ESN) is the oldest standard in this group. Created by the U.S. Federal Communications Commission (FCC) in the early 1980s, the ESN was designed to uniquely identify mobile devices operating on analog and early digital networks like AMPS, TDMA, and later CDMA. The ESN is a that manufacturers embed into a phone's microchip during production, and it typically appears on a label under the phone's battery or in the device's settings menu.
Add that final digit to the end of your 14-digit MEID to get the valid IMEI. Troubleshooting "Fixed" Converter Issues
