Validates format and check-digit only — it does not query live GSTN, DGFT or CBDT databases.
Instantly verify the structure of a GSTIN (15-digit), Import Export Code (10-char) or PAN, get a field-by-field breakdown, and validate the GSTIN check digit before you file on GST, DGFT or ICEGATE.

A GSTIN (GST Identification Number) is a 15-character code: 2-digit state code, the 10-character PAN of the entity, 1 entity-type code, the letter Z, and a final check digit. The GST portal, ICEGATE and bank systems all auto-validate it — a single character error rejects the return or filing.
An IEC (Import Export Code) is the 10-character DGFT registration number mandatory for every exporter and importer in India. The PAN is the Income Tax identifier whose 4th character indicates the entity type (C = Company, P = Individual, F = Firm, H = HUF, and so on).
Before applying for an IEC, mapping an AD Code or filing on ICEGATE, validate your identifiers here to avoid rejection and rework.
Frequently Asked Questions
What does the Z in a GSTIN mean?
The 14th character of a GSTIN is the fixed letter Z. It is a reserved structural character, and the 15th character is a mod-36 check digit computed from the first 14 characters.
My IEC has a different pattern — is it invalid?
Most IECs follow the 3-letter + 7-digit + 1-letter pattern, but older registrations may vary slightly. The validator flags the standard pattern; verify unusual cases on the DGFT portal before concluding.
Where is the entity type shown in a PAN?
The 4th character of the PAN indicates entity type: C (Company), P (Individual), F (Firm), H (HUF), A (AOP), T (Trust), B (BOI), L (Local Authority), J (Artificial Juridical Person), G (Government).
What is the GSTIN format?
A GSTIN is a 15-character alphanumeric code: 2 digits for the state code, 10 characters of PAN, 1 entity type code, the letter Z, and a final check digit. This validator verifies the structure and the check digit.
What is the IEC format?
An IEC (Import Export Code) is a 10-character alphanumeric code issued by DGFT. It typically follows a 3-letter, 7-digit, 1-letter pattern. The validator checks this structure.
Why validate before filing?
GST portal, ICEGATE and DGFT systems auto-validate identifiers. A typo in the GSTIN or IEC leads to instant rejection of returns, shipping bills or registrations. Validating first saves time and prevents compliance errors.
