Frequently Asked Questions
What is the IMEI code and how do I get it?
The IMEI code is a 15-17-digit number that identifies your mobile phone device. It can be obtained by dialing *#06# on your phone's dial pad.
It is a unique serial number that identifies each device. That is why the IMEI code is absolutely necessary to check your device or to unlock it. To request an IMEI check or a network unlock, you will need the first 15 digits of your IMEI code, even if it's longer than that.
IMEI stands for "International Mobile Equipment Identity," and it has the following structure:
- TAC (Type Allocation Code) - the first 6 digits
- Final Assembly Code (FAC) - digits 7 and 8 refer to the manufacturer
- SN (Serial Number) - the next 14 digits
- Spare - the last digit, it's just a verification digit.
How does the search by IMEI work?
In just a few seconds, we'll let you know the exact model of any phone for free so you can buy or sell it second-hand, or so that you can enter the correct model when requesting to unlock your phone.
For some checks, we will let you know of an equivalent model you can indicate to unlock your phone from its current network provider so you can use it with any network in the world.
You can also check the current status of your phone to see if it has been blacklisted or blocked by the network provider, if the warranty is intact, and for iPhones, if the iCloud Activation Lock has been enabled.
Where can I see if my phone is blacklisted?
To run the blacklist IMEI check, you need to make sure you have the correct IMEI by dialing *#06# on the dial pad, and not from the box, invoice, the back of the device, or under the battery.
Type it into the text box and the result will be displayed on screen.
If in doubt, we recommend that you double-check with the original carrier of the device as well, to ensure there are no pending issues with them.
