WHAT IS A PUK CODE?

These codes have been around quite a long time actually and PUK stands for 'PIN Unlock Key'. It's a unique code that is linked to your specific SIM card and is usually 8 digits long. Some phones may ask for a PUC code instead. This stands for 'PIN Unlock Code' and is exactly the same thing as a PUK Code.

To find the PUK number? The PUC code or PUK key is found on the SIM certificate, which you get when you first connect to a wireless network. Entering the PUK number will bring back the original unlocked status of your cellular phone. The PUK can also be obtained from the Network service provider.

A Personal Unlock Code (PUC), also known as a PIN Unlocked Key (PUK), is used in GSM mobile phones
Most mobile telephones offer the feature of personal identification number (PIN) protection. After switching on the phone, if the PIN security function is active, the user is requested to enter a 4-8 digit PIN enabling the phone's non-emergency calling functions. If the wrong PIN is typed in more than three times, either the SIM card, the device or both become locked. They can be reverted to their original unlocked state by entering a PUC, provided by the service operator through verification. If the wrong PUC is entered ten times in a row, the device will become permanently blocked and unrecoverable, requiring a new SIM card. Cellular phone users are therefore advised by most providers to keep their PUC written down in a safe place separate from the device.
The PUC (PUK) is a SIM-specific code assigned by the service provider. It is near-impossible to guess and enter it; thus, if a user does not know his or her PUC and is prompted for it, it should be obtained from the service provider.
Once you enter the PUK code, you must set a pin. The PUK (Personal Unblocking Key) and PUK2 are used to unlock the PIN and PIN 2 codes respectively if your SIM card is blocked
