What Is BSNL PUK Code & How To Get It?

Bharat Sanchar Nigam Limited or BSNL is one of the largest telecom operators in India. It provides telecom services across the country under its various business units. The Personal Unblocking Key (PUK) code, also known as the BSNL PUK code, plays an important role for all BSNL subscribers.

What Is The BSNL PUK Code?

A BSNL PUK code, which stands for Personal Unblocking Key, is a unique 10-digit code that can help unlock your BSNL SIM card if the PIN gets blocked due to incorrect entries. This is why all BSNL customers must note down their PUK code and keep it safe for future use.

Why Is The PUK Code Important For BSNL Users?

The PUK code is important because if the BSNL SIM PIN gets blocked after entering the wrong PIN multiple times, the only way to unblock it is by using the PUK code. Without the PUK code, you will not be able to make calls, send SMS, or use data on that SIM. So it is always recommended to keep the PUK code handy, especially if you have multiple SIMs from BSNL.

Where Do I Find PUK Code For BSNL SIM Offline?

The very first method to get your BSNL PIN code is to get it offline. To get it offline, first check the SIM card kit that came with your BSNL connection. Look for a plastic card that contains your SIM card, as the PUK code is typically printed on this card.

If you can’t find the card, try looking for the SIM card tray or the original box that came with your BSNL connection, as the PUK code might be printed on these items as well. If you’re still unable to locate your PUK code, you can contact BSNL customer service by dialing 1503 or 1800-180-1503 from another BSNL number.

Provide them with your BSNL mobile number, and they’ll be able to assist you in obtaining your PUK code. It’s important to keep your PUK code safe and not share it with anyone, as it’s sensitive information that can be used to unlock your SIM card if it’s been locked due to too many incorrect attempts at entering the PIN code.

What Happened if I Enter the BSNL PUK Code Incorrectly?

If the PUK code for a BSNL SIM card is entered incorrectly 10 times, the SIM card will get permanently blocked and will no longer be usable. The operator will then consider the SIM as lost/stolen and block it from the network. You will then need to purchase a new SIM card and port your old number (if possible) or get a new number issued. So always double-check the PUK code before entering it to avoid such situations.

Where Can I Find Help Regarding the BSNL PUK Code?

If you have somehow lost or forgotten your BSNL PUK code and need to retrieve it, here are a few options available:

  • Contact BSNL customer care through phone, email, chat, or visiting a local customer center. Provide your name, address, and mobile number for verification.
  •  Check the BSNL website for an online PUK retrieval process. Enter the required details correctly.
  •  As a last resort, visit any BSNL retail store along with valid ID proof to get a new PUK code issued.


Noting down the PUK code is important because once the SIM gets blocked, you will need the code to unblock it. However, the code is only provided once by the operator. If you lose the PUK code and the SIM gets blocked later, you will have to get a new SIM issued.

This is a long process and you may also lose your old mobile number. To avoid such hassles, always keep the PUK code in a safe place instead of just memorizing it. It is also advisable to note down the PUK code separately for all family SIMs.
