The keyword “MEID” refers to a specific type of unique identification number for a mobile device, crucial for network activation and device verification.
MEID stands for Mobile Equipment Identifier. It is a globally unique 14-digit hexadecimal code used primarily by carriers that operated on the CDMA (Code Division Multiple Access) network standard, such as older versions of Verizon and Sprint. The MEID serves the same purpose as the IMEI number—to uniquely identify a physical piece of phone hardware—but it is slowly being replaced by the more universally accepted IMEI standard.
This article explains the function of the MEID, how it compares to other identification numbers (IMEI/ESN), and provides clear steps for finding it on your device.

MEID vs. IMEI: The Key Differences
The confusion between MEID and IMEI stems from the historical division of global mobile networks.
The Network Divide
| Identifier | Full Name | Format | Primary Network | Status |
| MEID | Mobile Equipment Identifier | 14 hexadecimal digits (numbers 0-9 and letters A-F) | CDMA (Verizon, Sprint) | Mostly obsolete/superseded |
| IMEI | International Mobile Equipment Identity | 15 decimal digits (numbers 0-9 only) | GSM (AT&T, T-Mobile) | Global Standard |
- Same Purpose, Different Format: Both numbers serve as a unique, unchangeable device serial number, similar to a Vehicle Identification Number (VIN) for a car. They are used to prevent device fraud and blacklist stolen phones.
- Modern Relevance: Most modern smartphones, including those used on today’s unified Verizon and Sprint (T-Mobile) networks, are LTE/5G devices that are tracked primarily using the IMEI. However, if you are activating an older phone or dealing with a dual-technology device, the MEID may still be requested.
The Role of ESN (Electronic Serial Number)
The ESN (Electronic Serial Number) is an older, 11-digit number that predated the MEID. The MEID was created specifically to replace the ESN once the original supply of ESNs ran out. If a carrier asks for your ESN, they are usually referring to the MEID.

How to Find Your MEID Number
There are multiple ways to retrieve your MEID, regardless of whether you have an iPhone or an Android device.
Method 1: Universal Dialing Code (Quickest)
The easiest way to display both the IMEI and MEID (if applicable) is to use a universal short code on your phone’s dial pad:
- Open the Phone
- Dial *#06# (star-hash-zero-six-hash).
- The MEID/IMEI number(s) should immediately appear in a pop-up window.
Method 2: Device Settings
| On an iPhone | On an Android Device (General Steps) |
| 1. Go to Settings > General. | 1. Go to Settings. |
| 2. Tap About. | 2. Tap About Phone (or About Device/Tablet). |
| 3. Scroll down to find the MEID and/or IMEI. (On iPhones, the MEID is usually the IMEI without the last digit). | 3. Scroll down and look for the MEID or IMEI. (You may need to tap “Status”). |
Other Locations
- Original Box: The MEID/IMEI is typically printed on a sticker label on the original retail packaging.
- SIM Tray: On some devices, the number is laser-etched onto the SIM card tray.
- Behind the Battery: On very old phones with a removable battery, the MEID is often printed on a label underneath the battery.

Why the MEID Still Matters
Although the IMEI has become the global standard, your MEID is still important for these reasons:
- Activation: If you are activating a phone on an older CDMA-based network or using a smaller carrier (MVNO) that relies on those networks, the MEID is necessary for registration.
- Fraud Prevention: Law enforcement agencies and carrier databases (like the global IMEI/MEID database) use this number to verify the device’s status. If a phone is reported lost or stolen, its MEID/IMEI will be added to a blacklist, preventing it from being activated on any participating network.
- Warranty: The number is essential for manufacturers and carriers to process warranty claims and technical support.
