A letter that appears to come from SEBI can be unsettling, especially if it urges you to respond quickly. Before sharing information or taking action, check whether SEBI actually issued it. The regulator’s revised Document Number Verification System (DNVS) lets recipients verify a letter or notice using details printed on it.
What is new?
SEBI announced the revamp on 1 October 2026. Its current guidance note says the revised system has operated since September 2026. The check uses the document or outward number, the issuing official’s name, issue date, recipient’s name and the subject. The subject must match the communication exactly.
This is a useful way to check a claimed SEBI letter, notice or similar communication. It does not verify every financial message you receive, and it is not a check of whether an investment product or adviser is safe.
How to check a letter
- Go to SEBI independently. Type sebi.gov.in yourself and open “Authenticate Document Issued by SEBI” from its home page, or use the official verification page. Do not rely on a link in a suspicious message.
- Confirm who is checking. Enter your name, relationship to the recipient and mobile number, then complete the captcha and OTP step. A family member can check on the recipient’s behalf.
- Copy the letter’s details carefully. Enter the document number in the same format shown on the letter, plus the SEBI official’s name, issue date, recipient’s name and exact subject.
- Read the result narrowly. A match confirms that SEBI issued a communication with those details. SEBI expressly says this does not verify the contents of the letter.
For example, if your parent receives a notice bearing a SEBI-looking number, you can help run the check. A positive result is evidence about the communication’s origin. If the paper asks for money, passwords or urgent action, verify those instructions through contact information you find independently on SEBI’s official website before doing anything. Never give the portal OTP to someone who contacted you about the letter.
What if the system finds no record?
First, compare every field with the letter, particularly the number’s format and the subject. If the details are correct and the record still does not appear, SEBI’s guidance says to email dnvs@sebi.gov.in for verification. It also says communications issued before September 2026 should be checked by emailing that address with the necessary details.
Avoid guessing repeatedly: three failed verification attempts can block the mobile number for 24 hours, and further failed attempts after that can lead to a permanent block of that number from the system. Use the guidance note or email route if you are unsure of the fields.
The practical rule: Treat an official-looking seal, logo or document number as a reason to verify, not as proof. Check the source independently, then assess what the letter actually asks you to do.
