Green PIN is a paperless, OTP-based method to generate your debit or credit card ATM PIN instantly, no bank visit, no physical mailer. Introduced by SBI in 2016, it lets cardholders set their PIN via ATM, SMS, IVR, net banking, or missed call within minutes of receiving their card.
Green PIN is a digital PIN generation facility that allows debit and credit cardholders to create or reset their ATM PIN without receiving a physical PIN mailer. The term "green" reflects its paperless, eco-friendly nature: no printed letter, no courier, no waste.
The concept of Green PIN generation was pioneered by the State Bank of India (SBI) in 2016 as part of its push towards paperless banking. Recognising the inconvenience faced by millions of cardholders particularly those in rural and semi-urban areas who had to wait for physical PIN letters or visit bank branches, SBI introduced this facility to make card activation instant and accessible.
Under the Green PIN system, when a cardholder receives a new debit or credit card, they do not receive a pre-printed PIN. Instead, they generate their own PIN using an OTP (One Time Password) sent to their registered mobile number. This OTP-based process is available across multiple channels, including ATMs, SMS, IVR (Interactive Voice Response), and net banking, making it highly convenient regardless of where the cardholder is located. Most major Indian banks now offer the Green PIN facility.
Green PIN works through a secure OTP-based authentication flow that eliminates the need for a physical PIN mailer entirely. Here is the end-to-end process:
When a cardholder wants to generate their green pin, they initiate a request through any supported channel ATM, SMS, IVR, net banking, or missed call. The bank's system then verifies the cardholder's identity using their registered mobile number and card or account details.
Once the identity check is successful, the bank sends a One Time Password (OTP) to the cardholder's registered mobile number via SMS. This OTP serves as a temporary authorisation code, valid for 2 days from the time of issue. The OTP is not the PIN itself, it is a secure token that allows the cardholder to set their own PIN.
The cardholder then visits their bank's ATM, inserts the card, and selects the PIN generation option. At the terminal, they enter the OTP received on their mobile and a Request ID (where applicable) to validate the request. Once the OTP is validated, the system prompts the cardholder to enter and confirm a new 4-digit PIN of their choice.
The key difference from traditional PIN generation is that at no point does the bank create or know the cardholder's PIN; the cardholder sets it themselves. This makes the green pin process more secure, fully paperless, and instantaneous, with no waiting period for a physical mailer to arrive by post.
Green PIN offers meaningful advantages for both cardholders and banks making it a smarter approach to PIN generation across the board.
Traditional PIN mailers require printing, packaging, and courier delivery for every card issued consuming paper and generating carbon emissions at scale. Green PIN eliminates this entirely. With no physical letters sent, the initiative helps reduce the carbon footprint of both public and private sector banks across India. It is a small but meaningful step towards sustainable banking.
With a traditional PIN, cardholders often wait days or even weeks for a physical mailer to arrive before they can use their card. Green PIN removes this delay completely. A cardholder can generate their PIN the very same day they receive their card, enabling immediate card activation and usage at ATMs and POS terminals.
Under the traditional system, bank employees are responsible for handling and dispatching physical PINs — a process that carries inherent security risks. With Green PIN, the PIN is never held in physical custody by anyone. The OTP is sent directly to the cardholder's registered mobile number, and the cardholder creates their own PIN privately at the ATM. This end-to-end control significantly reduces the risk of PIN interception or misuse.
Generating, printing, and couriering physical PIN mailers to millions of cardholders involves substantial operational cost. Green PIN eliminates these expenses entirely. Banks save on paper, printing, courier charges, and associated logistics — savings that can be passed on to customers in the form of better services.
If a cardholder forgets their PIN, the traditional process for getting a duplicate PIN can take several days. With Green PIN, a duplicate PIN can be generated almost instantly using the same OTP-based process, through any of the supported channels. This drastically reduces downtime and customer inconvenience.

Most major Indian banks now support Green PIN generation. Below are the specific processes for key banks.
SBI was the first to introduce Green PIN generation in India. SBI debit cardholders can generate their green pin via ATM, SMS to 567676 (format: PIN <last 4 digits of card> <last 4 digits of account>), IVR via SBI's toll-free number, or through SBI's net banking portal under Cards → PIN Generation. The OTP received is valid for 2 days and must be validated at an SBI ATM to complete PIN creation.
HDFC Bank customers can generate their PIN through HDFC's net banking portal (Cards section → Debit Card PIN Generation), HDFC's mobile banking app, IVR by calling HDFC's 24x7 customer care, or at an HDFC Bank ATM. Cardholders are sent an OTP on their registered mobile number, which is used for verification before setting the PIN.
IDFC FIRST Bank cardholders can generate or reset their debit card PIN through the IDFC FIRST Bank mobile app, net banking portal, or by calling the bank's customer care. The OTP-based flow is consistent with the standard Green PIN process.
Kotak Bank customers can generate their debit card PIN via the Kotak Mobile Banking app under the Cards section, through net banking, or by calling Kotak's customer care IVR. PIN generation via SMS is also supported for registered mobile numbers.
YES Bank cardholders can generate their ATM PIN by logging into YES Bank's net banking portal or mobile app, navigating to Cards → PIN Generation, and completing OTP validation on the portal itself. No ATM visit is required if the PIN is set through net banking.
SBM Bank India cardholders can generate their debit card PIN through SBM's net banking portal or by contacting SBM customer care. The standard OTP-based Green PIN flow applies — cardholders receive an OTP on their registered mobile number, which is used to authenticate PIN creation.
Green PIN is a secure and well-designed system, but there are a few key points every cardholder should be aware of.
OTP Validity The OTP sent during the Green PIN process is valid for 2 days (48 hours) from the time it is issued. If the OTP expires before you complete the PIN creation process, you will need to initiate a fresh Green PIN request.
Never share your OTP with anyone — not even bank representatives.
Do not use easily guessable PINs such as 1234, 0000, or your date of birth.
Change your PIN immediately if you suspect it has been compromised.
Always shield the keypad when entering your PIN at an ATM or POS terminal.
Ensure no one is watching when you validate the OTP at the ATM.
Register and update your mobile number with the bank to ensure OTPs are delivered only to you.
Green PIN can only be generated at your own bank's ATM — be wary of any messages or calls asking you to use another bank's terminal.
Green PIN generation is the process of creating your debit or credit card ATM PIN digitally, using an OTP sent to your registered mobile number — without any physical PIN mailer or bank visit.
Send an SMS from your registered mobile number to 567676 in the format: PIN <last 4 digits of card> <last 4 digits of account number>. You will receive an OTP that you must validate at your bank's ATM to set your PIN.
Yes. Green PIN is secure — the OTP is sent only to your registered mobile number, the PIN is set by you and never known to the bank, and no physical document containing your PIN is ever sent.
Yes. Log in to your bank's net banking portal, go to the Cards section, select PIN Generation, and validate the OTP sent to your mobile. Some banks allow you to complete the entire process online without visiting an ATM.
