A PUK code, short for Personal Unblocking Key, is a unique eight-digit code used to unblock a SIM card that has been locked by a network operator. Operators lock a SIM card when an incorrect SIM PIN has been entered multiple times. The PUK code is also known as the Network Unblocking Code (NUC) or Personal Unblocking Code (PUC).

The PUK code is usually found in the documentation or the card holder that the SIM card came in.
