Your PUK code, or Personal Unlocking Key is an authorisation codes that protects your mobile phone security. It's rare that customers ever never need to know what it is, unless they lock their phone by entering an incorrect PIN number. Depending on what network you're on and what device you own, depends on how you can retrieve your PUK code.
For example, if you're a vodafone user, you can log into you online account and find it located under the 'Manage my devices' section. Most, if not all networks will have a similar option on their website, so the first port of call is to look online under the 'help' or 'frequently asked questions' sections to find out the procedure. If you've blocked your Sony Ericsson phone by entering you PIN code incorrectly more than 3 times, you will see a message on the screen. If you see the message 'Pin blocked - Unblock?' - your phone itself is blocked and you will need your PUK code.
Whereas, if it says 'Blocked - Contact your Card Provider', it's your SIM card (known in full as Subscriber Identity Module) that is blocked, so you will need to contact your network and request that they send you a replacement. The reasoning behind PUK codes is to prevent criminals from accessing your phone if it is lost or stolen. It is illegal for anyone to attempt to unblock a mobile phone, other than the network provider who put the block on the device. If you are still unsure of what to do, find the helpline of your network provider and they will be able to assist you over the phone, given you have your account details to hand. PUK codes are commonly confused with PAC codes, which allow you to transfer your existing mobile phone number from one network provider to another.
