PUK Codes Explained

PUK :: Personal Unblocking Key

This article describes PUK codes. If you are looking for a PAC code visit www.paccodes.co.uk, and if you are looking for a network unlocking code (NUC code) visit www.nuccodes.co.uk.

PUKs, or personal unblocking keys, are used to unblock a mobile phone which becomes blocked. Mobile phones may become blocked when a PIN (personal identification number) is entered incorrectly on three consecutive occasions. In some instances, the phone may become blocked, which requires a PUK to unblock it, and in other instances, the SIM (Subscriber Identity Module) card itself becomes blocked and again will require a PUK to unblock it.

Mobile phones are also blocked when they are reported stolen and if there is an outstanding payment on the account.

It is important to differentiate between unblocking phones (using a PUK) and unlocking mobile phones (using another type of code). More information on unlocking phones will be available here in the very near future.

NOTE: It is a criminal offence for anyone to attempt to unblock a mobile phone, other than the network provider who put the block on the phone.

If your phone has become blocked by mistake, for example you have entered the PIN incorrectly on three consecutive occasions, then you need to contact the mobile phone network operator with your details.
