If you've accidentally lost your mobile phone or worse, it got stolen, and you didn't have a chance to get it back, don't fret.

In this guide, you will get to block your lost or stolen phone using its IMEI. Or else, the thief can't use or sell it. Take note that this guide is for phones lost in the Philippines only.

What is IMEI?

The IMEI stands for International Mobile Equipment Identity. It is usually composed of 15 decimal digits (for IMEI) or 16 decimal digits (for IMEI/SV) that include information on the origin, model, and the device's serial number. Every phone has a unique IMEI number that enables service providers to identify it. It is typically printed on the battery compartment of older phones, while newer smartphones, either Android or Apple, have it printed on the box.

How to Find My Phone's IMEI?

The IMEI number can be found on the box or other documentation that came with your phone (i.e., receipt).

IMEI can also be displayed on-screen on most phones by dialing *#06# (USSD code). Additionally, dual SIM cards will display two IMEI numbers on the screen, one for each of the two GSM modules contained within. Block both IMEIs on the form.

What is IMEI Blocking?

Since mobile networks can identify phones connected to them via IMEI, they can be requested to blacklist or deny service to a specific device. It will be implemented by the National Telecommunications Commission (NTC), the government agency that oversees network operators in the Philippines. If the NTC approves your request, your phone's access to all networks in the country will be disabled, effectively rendering it useless.
