GST State Code 37 — Andhra Pradesh
GST state code 37 is the code for Andhra Pradesh. Any GSTIN beginning with “37” was issued to a business registered in Andhra Pradesh under the Goods and Services Tax.
Where the code sits inside a GSTIN
A GSTIN is exactly 15 characters. The first two digits are the state code — 37 for Andhra Pradesh. Characters 3 to 12 are the PAN of the registered business, character 13 counts that PAN's registrations within the state (1–9, then A–Z), character 14 is the letter “Z” by default, and character 15 is a check digit computed from the first fourteen.
Worked example (fictitious PAN, valid structure and check digit):
37ABCDE1234F1ZZ
Here 37ABCDE1234F1ZZ reads as: registered in Andhra Pradesh, PAN ABCDE1234F, first registration for that PAN in the state, with a mathematically valid check digit. Do not invoice against example numbers — always verify the real GSTIN first.

Frequently asked questions
Which state has GST state code 37?
GST state code 37 belongs to Andhra Pradesh. Every GSTIN issued to a business registered in Andhra Pradesh begins with the digits 37.
Where does the state code appear in a Andhra Pradesh GSTIN?
The state code is always the first two characters of the 15-character GSTIN. If a GSTIN starts with 37, the registration was issued in Andhra Pradesh. Characters 3–12 are the PAN of the business, character 13 is the entity number, character 14 is always “Z”, and character 15 is a checksum.
Is the GST state code the same as the state's vehicle or census code?
No. GST state codes follow the Indian Census 2011 numbering adopted by GSTN, which is different from RTO vehicle registration codes. Always use the two-digit GST code when filing returns or raising invoices.
What does it mean if my supplier's GSTIN does not start with 37 but they claim to operate from Andhra Pradesh?
It usually means the supplier is registered in a different state and supplies to Andhra Pradesh inter-state (IGST applies instead of CGST+SGST). If they invoice you claiming local registration with a mismatched state code, verify the GSTIN before paying — the place of supply affects your input tax credit.
Can one business have more than one GSTIN in Andhra Pradesh?
Yes. A business with multiple verticals or units in Andhra Pradesh can hold multiple GSTINs, all starting with 37 and sharing the same PAN — only the 13th character (entity number) differs. Search by PAN on GST Search to see every registration held by one PAN.
