GST State Code 28 — Undivided Andhra Pradesh
GST state code 28 is Andhra Pradesh (pre-bifurcation). Every GSTIN issued in Andhra Pradesh begins with 28 — the first two characters of a GST number are always the code of the state or union territory that granted the registration. Code 28 is no longer issued to new registrations, but it remains valid on GSTINs granted before the change.
Example GSTIN registered in Andhra Pradesh
28AAACR5055K1Z5
Structurally valid and checksum-correct, but illustrative — it is not an issued registration. The highlighted 28 is the state code; the ten characters after it are the holder’s PAN.

Where 28 sits inside a GST number
A GSTIN is 15 characters in a fixed layout. The state code is the part that tells you where the registration was granted, and it is the only part that identifies a place.
| Position | Example | What it is |
|---|---|---|
| 1–2 | 28 | The GST state code — Andhra Pradesh (pre-bifurcation) on this page. |
| 3–12 | AAACR5055K | The holder’s PAN, embedded unchanged. This is why one PAN search returns every GSTIN issued to a business across all states. |
| 13 | 1 | Counts registrations held against the same PAN within Andhra Pradesh. A second registered business vertical in the same state gets 2, and so on. |
| 14 | Z | A fixed letter on every regular GSTIN. It carries no information. |
| 15 | 5 | A check digit computed from the first 14 characters. It catches typos — it does not prove the number was ever issued. |
Because the checksum algorithm is public, a fabricated number can pass a format check and still be entirely fictitious. Confirming that a 28 GSTIN actually exists means looking it up against the live register. Full breakdown of the format: what a GST number is made of.
CGST + SGST or IGST on a Andhra Pradesh supply?
Comparing state codes is the first check, and for most supplies it settles the question.
Your GSTIN starts 28, place of supply in Andhra Pradesh
Intra-state supply. Charge CGST + SGST, split evenly between the centre and the state.
Your GSTIN starts with any other code
Inter-state supply. Charge IGST at the combined rate, which the centre later apportions to the consuming state.
One caveat worth keeping: the place of supply is not always the customer’s billing address. For several categories of service the IGST Act points somewhere else entirely, so treat the state code as the starting point rather than the conclusion.
Cities and districts under code 28
GST state codes are assigned per state or union territory, never per city. Every business registered anywhere in Andhra Pradesh carries 28 — including Hyderabad and Visakhapatnam. There is no separate GST code for a city, a district or a commissionerate.
