How to Blacklist a Stolen Phone via IMEI
Published: August 29, 2026 • 3 min read
What is IMEI Blacklisting?
Every mobile phone has a unique 15-digit identifier called the **IMEI (International Mobile Equipment Identity)**. Blacklisting an IMEI means registering the device identifier as blocked or stolen on the carrier registry databases. Once blacklisted, the phone **cannot connect to any mobile network in Kenya** (Safaricom, Airtel, Telkom) to make calls, send SMS, or use cellular data, effectively turning it into a brick.
How to Blacklist Your Phone in Kenya
To request a network block on your stolen phone:
1. Get your OB Number & Abstract
Visit the nearest police station and report the theft to receive an **Occurrence Book (OB) Number** and request a stamped Police Abstract. This document is legal proof of the theft.
2. Visit a Customer Care Center
Take your National ID Card, the Police Abstract, and proof of purchase (showing the device IMEI) to any Safaricom, Airtel, or Telkom retail shop.
3. Deactivation via Communications Authority (CA)
The mobile operator logs your request in the central equipment identity database. This is communicated to the **Communications Authority of Kenya (CA)**, which coordinates with all other national carriers to block the IMEI across the entire country.
How to Check if a Phone is Stolen or Blocked
If you are buying a second-hand phone in Kenya, you should always check if it has been blacklisted or reported as stolen:
- Dial ***#06#** on the phone to display its IMEI number.
- Enter this IMEI into our **[Stolen Phone Checker](https://lostphoneke.web.app/search)** database.
- Check if the IMEI has been reported in our public registry.
- Insert your SIM card and verify that the phone can receive cellular signals and make a call. If it shows "No Service" or "Emergency Calls Only" despite an active SIM, it might be carrier blacklisted.
Be aware that tech-savvy thieves sometimes change a phone's IMEI permanently using software hacking tools (known as flashing). However, this is highly illegal under the Kenya Information and Communications Act, and modern smartphones make changing the IMEI virtually impossible.
