HSN & SAC code checker
Paste a code and see whether it is well-formed, and what each pair of digits actually means. Runs in your browser — nothing you type leaves this page.
Tired of looking these up per invoice? Sally stores the HSN code and GST rate on each stock item, so the right tax lands on the invoice without anyone typing it.
How the hierarchy works
| Digits | Example | Level |
|---|---|---|
| 1–2 | 30 | Chapter — broad category of goods |
| 3–4 | 3004 | Heading — group within the chapter |
| 5–6 | 300490 | Sub-heading — the international standard level |
| 7–8 | 30049099 | Tariff item — India-specific breakdown |
Services use SAC codes instead: six digits beginning with 99.
Questions
Does this tell me the GST rate for a code?
No, and that is deliberate. GST rates change by notification and vary by description within the same heading. Publishing a rate we had not verified against the current CBIC schedule could lead someone to under-charge tax and receive a demand notice. This tool checks structure only — for the rate, use the current CBIC rate schedule or ask your CA.
How is an HSN code structured?
The first two digits are the chapter, a broad category of goods. The next two are the heading, a group within that chapter. The next two are the sub-heading, which is the internationally standard six-digit level. Indian tariff adds a further two digits, making eight in total.
What is a SAC code?
SAC codes identify services rather than goods. They are six digits and begin with 99, which is the services chapter. This tool recognises them and breaks them down the same way.
How many digits do I need on my invoice?
The number of HSN digits you must report depends on your aggregate turnover, and the thresholds have been revised more than once since GST began. Check the current requirement before you set your invoice format — your CA will know the position that applies to you now.
Where does the number I type go?
Nowhere. The check runs entirely in your browser; nothing is sent to a server.
Set it once, not every invoice
In Sally the HSN code and GST rate live on the stock item, so every invoice picks them up automatically — and the HSN summary for your GSTR-1 builds itself.
