How to Track a Lost Phone Using IMEI Number

5 min readUpdated 6/1/2025

Can You Track a Lost Phone with Its IMEI Number?

IMEI tracking is often misunderstood. While you cannot track a lost phone yourself using only the IMEI, law enforcement and carriers can use it — and there are other methods you can use right now. Here's what works, what doesn't, and the fastest ways to locate or block your lost device.

What IMEI Tracking Actually Means

When a phone connects to a mobile network, it broadcasts its IMEI to the carrier's towers. Carriers log which IMEI is on which tower at what time. This means:

  • Carriers can locate a phone using IMEI — but they only provide this to law enforcement with a valid warrant or court order
  • You cannot directly track your IMEI yourself via the carrier's system
  • Police can request IMEI location data from carriers to assist with theft investigations

What You CAN Do Right Now (Without Police)

For iPhones — Find My iPhone:

  1. Go to icloud.com/find on any browser
  2. Sign in with your Apple ID
  3. Select "All Devices" → choose your iPhone
  4. Options: Play Sound (phone rings), Lost Mode (locks phone + shows contact message), Erase iPhone
  5. Lost Mode is best — it locks the phone, tracks its location updates in real time, and shows your contact number on the lock screen

For Android — Find My Device:

  1. Go to android.com/find
  2. Sign in with the Google account linked to the phone
  3. Options: Play Sound, Secure Device (locks with PIN + contact message), Erase Device
  4. Location shown on map if phone is on and connected to internet/mobile data

Track Lost Phone via Mobile Network (Police Required)

  1. File a police report with your IMEI number — this is essential. Police cannot act without a report.
  2. Provide police with your IMEI and proof of ownership (box, receipt, carrier account showing IMEI)
  3. Police submit an IMEI location request to your carrier
  4. Carrier provides tower-level location data to police
  5. For active investigations, police coordinate with the carrier for real-time location pings

IMEI Blocking — Make the Phone Useless to the Thief

If you cannot recover the phone, the next best step is blocking the IMEI so the thief cannot use it on any carrier network:

  1. Contact your carrier with your IMEI and police report number
  2. Request IMEI blacklisting — the phone becomes unusable on all networks in your country
  3. Report to the national IMEI database (India: sancharsaathi.gov.in; UK: actionfraud.police.uk; Australia: state police portals)

Third-Party IMEI Tracking Apps — Do They Work?

Many apps and websites claim to track any phone by IMEI for a fee. These are almost universally scams. No app or website has the ability to query carrier tower location data — that requires law enforcement authorization and direct carrier access. Do not pay for "IMEI tracking services" on the internet.
