UDIN stands for Unique Document Identification Number - an 18-digit number generated by the Institute of Chartered Accountants of India (ICAI) and stamped on documents certified by a practising CA. It exists to stop forgery: anyone receiving a certificate can verify on the ICAI UDIN portal that a genuine CA with a valid Certificate of Practice actually issued it.
If you are getting a net worth certificate, UDIN is not optional - here is why it matters.
Is UDIN mandatory on a net worth certificate?
Yes. ICAI made UDIN mandatory in phases, and certificates - including net worth and turnover certificates - have required a UDIN since 1 July 2019. A certificate issued by a practising CA must carry the 18-digit UDIN, or the receiving authority cannot authenticate it.
How to verify a UDIN
Verification is public and free:
- Go to the ICAI UDIN portal (udin.icai.org) and choose "Verify UDIN".
- Enter the 18-digit UDIN printed on the certificate.
- The portal confirms the issuing CA's membership number, the date, and the document type - proving the certificate is genuine.
Where a UDIN-stamped net worth certificate is required
Banks (for loans and credit facilities), embassies and consulates (for visa applications), tender and government authorities, demat and franchise onboarding, and SEBI-related filings all insist on a UDIN-authenticated certificate. For visa use specifically, see our dedicated net worth certificate for visa page.
