SEBI revamps document verification system, adds subject matter as mandatory field

New business data points to the fact that To strengthen the authentication of regulatory communications market regulator Securities and Exchange Board of India (SEBI) has revamped its Document Number Verification System (DNVS). The regulator has further noted the subject matter of a letter as a mandatory field.

SEBI had rolled out the Document Number Verification System in April 2025 to allow recipients to verify whether a physical letter or notice, including show-cause notices, was actually issued by the regulator.

Under the revamped system, the format has additionally been aligned with the outward number generated through SEBI's e-Office system, according to a press release issued today.

Recipients of a SEBI letter, or any person acting on their behalf, can verify the authenticity of the communication by entering the mandatory details after validating their credentials.

The details required include the outward number, name of the SEBI official issuing the letter, date of the letter, subject matter and name of the recipient.

If the details entered match SEBI's records, the system will confirm that the letter or communication was issued by the regulator.

If the details do not match, the system will indicate that no record has been found. The verifier can then re-enter the details or seek confirmation from SEBI by emailing dnvs@sebi.gov.in.

SEBI, that stated, clarified that verification through the system only confirms whether the communication was issued by the regulator and does not constitute verification of the contents of the letter.

The revamped system has been operational since September 2026.

SEBI stated communications issued before September 2026 can be verified by sending an email with the necessary details to dnvs@sebi.gov.in.

The Document Number Verification System keeps be available on the home page of the SEBI website under Authenticate Document Number Issued by SEBI.
