Every iPhone, including the iPhone 18 series and earlier models, has a unique number called an IMEI. IMEI stands for International Mobile Equipment Identity, and it uniquely identifies your device on cellular networks. You can find your iPhone IMEI on the original packaging, in Settings > General > About, or by dialing *#06# from the Phone app keypad.

Sometimes, an iPhone may show an IMEI-related problem, such as a missing or invalid IMEI number, which can affect cellular service. If this happens, you may need to learn how to troubleshoot an IMEI issue on iPhone through safe software checks, carrier support, or Apple service options. Do not attempt to change an IMEI number, as it is a device-specific identifier.

The following guide explains how to check the IMEI number on your iPhone, including iPhone 18 models, identify common IMEI-related issues, check whether an IMEI may be blacklisted, and understand the appropriate next steps.

Ask the Seller for a Refund

If you have bought your iPhone from a genuine seller, they should be able to issue you a refund or a replacement. Most trusted websites will happily do it for you, however, if you have bought the phone from a not so genuine seller, they may or may not issue you a refund and/or replacement.

Put in an IMEI Clean Request

In some events, it is possible to get your IMEI number cleaned. To do that, you need to put in a request to your carrier letting them know your exact situation. They might be able to whitelist your IMEI number.
