How a Bihar GSTIN is put together
The number opens with 10 for Bihar, followed by the taxpayer's ten-character PAN, a digit or letter for how many registrations that PAN holds in Bihar, the default letter Z, and a checksum character. A full breakdown is on the GSTIN format page.
We check the pattern and checksum before running a lookup, so a mistyped Bihar GSTIN is caught instantly. Valid numbers go through to a live registration lookup that reports whether the registration is active, cancelled or suspended — see GST status check.
We do not publish lists of Bihar taxpayers or their GSTINs. Search a specific number you already hold, such as one printed on an invoice.
