SEBI has made a letter’s subject a compulsory entry in its Document Number Verification System. In a press release dated October 1, the securities regulator explained the revised service and its limits. The system has been operational in its updated form since September 2026; this is a new public disclosure of that change, rather than a service first launched today.

Recipients checking a physical letter or notice must enter its outward number, the issuing official’s name, its date, subject and recipient’s name after validating their credentials. The format now follows the outward-number system used by SEBI’s electronic office. The original verification service began in April 2025.

The distinction between a genuine dispatch and an authenticated text is important. SEBI says a matching result establishes that a communication bearing those details was issued by it. It does not certify the letter’s contents. Moneycontrol and Business Standard independently reported that qualification on October 1.

A result showing no record calls for checking the entered information or asking SEBI for confirmation, the release says. Communications issued before September can be checked through the regulator’s designated email address, dnvs@sebi.gov.in. The service remains linked from SEBI’s homepage under document-number authentication. Outlook Money’s October 2 report places the change in the context of forged regulatory notices. No figures demonstrating a reduction in such fraud were provided in the release.
