What is an IMEI Number and How to Find It on Your Phone

Our phones contain more information than many people realise. Most users know that phones hold personal data such as emails, contact details and messages. However, every phone also has a unique IMEI number. A quick lookup of that number can tell manufacturers and service providers a great deal about the device.

The Difference Between an IMEI and a Serial Number

A serial number mainly serves the manufacturer. It can show where the phone was made, whether it is still under warranty and, if you send it for repair, help identify the device correctly. You can usually find the serial number in the phone’s “About” section. Some models also show it on the back of the device.

An IMEI serves a similar purpose, but it goes further. It still identifies the device, yet it also helps protect users if the phone is lost or stolen. In that sense, it works rather like a car’s VIN. It gives access to information about the handset and its history.

For example, if you take your phone to a high street recycler that uses MobiCHECK, a quick IMEI lookup can show whether the phone has been reported lost or stolen.

How to Find Your IMEI Number

Finding your IMEI number is usually straightforward. The quickest method works on both iPhone and Android devices. Open the phone app and enter *#06# on the keypad. Your IMEI number should then appear on the screen.

This method is simple because it does not require you to search through settings menus.

For iPhone users, there is another option if you prefer to check the settings:

1. Open the Settings app.
2. Scroll to and select General.
3. Tap About.
4. Scroll down until you see the IMEI number.

Older iPhone models may also show the IMEI on the back cover or on the SIM tray.

For Android users, you can usually find the IMEI through the settings as well:

1. Open the Settings app.
2. Scroll down and tap About Phone or About Device.
3. Select IMEI Information.

Some Android menu labels vary slightly depending on the manufacturer and the version of Android installed on the device.

Is There Personal Information Attached to an IMEI?

The information linked to an IMEI mainly relates to the device itself. It does not usually contain the user’s name, address or SIM number. However, network and usage information connected to an IMEI can become sensitive in the wrong hands. For that reason, it makes sense to share your IMEI only with trusted providers, such as MobiCode.

What Information Does an IMEI Hold?

The basic information stored against an IMEI relates to the handset. That includes details such as the make, model and specifications of the device. Carriers can use that information to understand what the phone is and what it is supposed to do.

The main reason IMEI numbers matter is their role in identifying lost or stolen phones. Each time a phone connects to a network, the IMEI is part of that process. This helps the network recognise the device and connect it appropriately.

That connection history can also help providers and relevant authorities understand the last known network activity of a device in appropriate circumstances.

In the UK, IMEI numbers also link to national databases that allow networks and service providers to see whether a phone has been reported lost or stolen. Once the owner reports the device, the network can blacklist it. As a result, if someone later tries to sell or process that handset, the status can be flagged.

MobiCode builds its MobiCHECK device check around an IMEI lookup. We then apply that information across a wide range of datasets to support a broader analysis of a phone’s history.
