An IMEI number, standing for International Mobile Equipment Identity, is a unique digital fingerprint assigned to every legitimate mobile phone. This specific sequence identifies the device itself on a cellular network, distinct from the SIM card which identifies the subscriber. Understanding what this identifier looks like and where to find it is essential for device registration, warranty verification, and, most importantly, protecting your phone in the event of loss or theft.
Basic Structure and Visual Format
The most common answer to what an IMEI looks like is a string of 15 digits, although a 16-digit variant known as IMEISV exists for software version tracking. Visually, it is often presented as a continuous block of numbers or, for readability, broken into groups separated by slashes or spaces. The typical format is either AA-BBBBBB-CCCCCCC-D or AA BB BB CC CC CC CC D, where "A" represents the Type Allocation Code, "B" the Final Assembly Code, "C" the Serial Number, and "D" the Luhn check digit. This rigid structure ensures global uniqueness and allows for easy verification by network equipment and support professionals.
Visual Examples of Valid Formats
To provide clarity, here are specific examples of how this identifier is commonly displayed:
Compact form: 490154203237918
With slashes: 49-015420-323791-8
With spaces: 49 015420 323791 8
These variations are purely cosmetic; the underlying number remains the same. The first two digits often indicate the country code or final assembly location, while the middle section specifies the model and serial number. Regardless of the spacing, the total count of meaningful digits usually adheres to the 15-digit standard.
Where to Locate the Identifier
Finding the identifier is straightforward depending on your level of access to the device. For most users, the easiest method is to check the Settings menu. Navigate to Settings, then About Phone, and finally Status, where the number will be listed clearly on the screen. Alternatively, physically inspecting the device provides a permanent reference. On the original packaging, the barcode section usually features a small text line below the QR code displaying the exact number. For devices with removable batteries, the identifier is often printed directly on the battery tray itself.
Using the Keypad Method
If you have access to the phone but cannot navigate the settings, dialing a specific code retrieves the information instantly. By opening the phone dialer and entering *#06#, the full identifier will immediately pop up on the screen. This method works universally across nearly all mobile platforms, including iOS, Android, and legacy feature phones. It is a reliable diagnostic tool that requires no menu diving and provides instant results for verification or reporting purposes. Distinguishing from Similar Identifiers It is important to differentiate the IMEI from other identification codes found on mobile devices. While the IMEI identifies the hardware, the MEID (Mobile Equipment Identifier) is used by CDMA networks like Verizon and Sprint and typically contains hexadecimal characters (numbers and letters A-F) rather than just numbers. Similarly, the ICCID found on a SIM card identifies the SIM card itself. When someone asks what an IMEI number looks like, they are specifically referring to the 15-digit numeric string, not these other alphanumeric serial codes.
