Cheque Book New Rules 2026: Check If Your Cheque Has This New Security Code

If you still use cheques for banking transactions, it is worth checking whether your cheque book carries the latest security features. Banks have been introducing cheque books with an alphanumeric code as part of measures to improve cheque security and reduce the risk of fraud.

Bank of India (BOI), for instance, has introduced an alphanumeric code on its cheque leaves and has advised customers to use the newer series of cheque books. The code contains a combination of letters and numbers and is intended to help with the identification and verification of cheques.

Customers who regularly use cheques, particularly for high-value payments, should check with their bank whether their existing cheque book needs to be replaced.

Why Are Banks Introducing New Cheque Books?

The introduction of additional security features is aimed at making cheque transactions safer and reducing the risk of fraudulent or tampered cheques.

The Reserve Bank of India (RBI) has also been strengthening the cheque clearing system through the Cheque Truncation System (CTS). Under CTS, the physical movement of a cheque during the clearing process is stopped and its electronic image and relevant data are sent to the paying bank for processing.

The RBI has been moving towards faster cheque clearing, with the system designed to reduce the time taken to process cheque payments.

What Is The Alphanumeric Code On A Cheque?

An alphanumeric code is a combination of letters and numbers printed on the cheque. Banks use such security features to help identify cheque leaves and strengthen verification during processing.

Bank of India introduced an alphanumeric security code on its cheque leaves and has encouraged customers to replace older cheque books with the new series.

However, customers should check their individual bank's latest instructions rather than assume that an old cheque book has automatically become invalid.

What About The December 31, 2026 Deadline?

There have been reports about a December 31, 2026 deadline for certain cheques without the alphanumeric code, particularly for cheques of Rs 50,000 or more.

However, customers should check their bank's official communication before assuming that this is a universal RBI deadline applicable to all banks.

The safest step is to contact your bank or check its official website to find out whether you need to replace your existing cheque book and whether any deadline applies to your account.

What Will A New Cheque Book Cost?

The cost of a cheque book varies between banks and depends on the type of account.

At Bank of India, savings account customers are entitled to 25 free cheque leaves in a financial year. Additional cheque leaves are charged according to the bank's applicable service charges.

Customers should check their bank's current tariff before ordering an additional cheque book.

How Long Is A Cheque Valid?

A cheque is generally valid for three months from the date written on it. Customers should therefore ensure that cheques are deposited within the validity period.

If a cheque is returned unpaid, it can have financial and legal consequences. In certain circumstances, cheque dishonour can attract action under Section 138 of the Negotiable Instruments Act, 1881.

Why Do People Still Use Cheques?

Despite the growing use of digital payments, cheques continue to be used for certain transactions, including payments involving businesses, property, loans and other financial arrangements.

Cheque payments also provide a documented record of a transaction through bank records.

For customers who continue to use cheques, the important point is to follow their bank's latest instructions on cheque books and security features.

If your bank has asked you to replace an older cheque book, it is advisable to do so before making your next high-value payment.
