Introduction to PUK Codes
A PUK code is an 8-digit number assigned to your SIM card by your mobile network provider.

What is a PUK code and how does it relate to SIM card security?
A PUK code, or Personal Unblocking Key, is a unique code assigned to a SIM card that helps to unlock it when it becomes blocked due to incorrect PIN entry. The PUK code is usually an 8-digit number that is provided by the mobile network operator when the SIM card is first issued.
