Frequently asked questions
How is a GSTIN structured?
2-digit state code, 10-character PAN, entity number, the letter Z by default, and a check character.
What does the check digit catch?
Almost all single typos and swapped characters, so a wrong GSTIN on an invoice is caught early.
Does it confirm the GSTIN is active?
No. Use ‘Search Taxpayer’ on gst.gov.in for the legal name and status.
