MarkRTD Seller Tools

GST Registration Search

Search any GST number to see if the registration is Active, with the legal name, business type, registration date and address.

Search a GST Registration by GSTIN

Type a 15-character GSTIN above to see whether the registration is Active, Cancelled or Suspended, with the legal and trade name, business type, registration date, jurisdiction and address. Use it to check a supplier or buyer before you deal with them or claim input tax credit.

A GSTIN is built from the state code (first 2 digits), the PAN (next 10 characters), the entity number, the letter Z and a check character. The tool also checks the format before searching.

Frequently asked questions

Can I search GST registration by name?

This tool searches by GSTIN. The GST portal also offers a search by PAN.

What does Cancelled mean?

The registration is no longer valid; don’t accept GST invoices from that GSTIN.

Is this the official GST search?

No. It is an independent tool by MarkRTD, showing details from the GST registry.
