HSN (Harmonized System of Nomenclature) is an internationally standardised system of codes used to classify goods. Under GST in India, HSN codes are used on invoices and returns to identify the product and apply the correct tax rate.

What is the difference between HSN and SAC codes?

HSN codes classify goods (physical products), while SAC (Services Accounting Code) classifies services. This finder searches both — results are tagged as HSN or SAC.

How many digits should an HSN code have?

It depends on turnover. Businesses with turnover up to ₹5 crore generally use 4-digit HSN codes, and those above ₹5 crore use 6-digit codes. Imports and exports use 8-digit codes. Always confirm the digit requirement applicable to your business.

Is this HSN code finder free?

Yes — it is completely free and needs no login. To auto-apply HSN/SAC codes and the right GST rate on every invoice, you can start a free trial of KhataBuddy.

How do I find the HSN code for my product?

Type the product name or a part of it in the search box above. The tool fuzzy-matches your keyword against the official HSN/SAC list and shows the closest codes with descriptions.

How do I verify or check an HSN code?

Type the HSN code (or part of it) into the search box and confirm the description that appears matches your product or service. Cross-checking a code against its official description is the simplest way to verify you are using the correct HSN/SAC code before issuing a GST invoice.

How do I check an HSN code online?

Type the HSN code or the product name into the search box above — this free online HSN code finder instantly checks it against the official HSN/SAC list and shows the matching code and description, so you can confirm it before billing.

Is there a free SAC code finder?

Yes — this tool is a SAC code finder too. Search by a service name (for example, “advertising” or “consulting”) or a SAC number and it returns matching SAC codes, tagged separately from HSN codes.

Can I use this as an HSN code validator?

Yes. Enter an HSN code and check that the description shown matches your product — a quick way to validate that you are using the correct HSN code on your GST invoices and returns.

What is an HSN code validator?

An HSN code validator is a tool that checks whether an HSN or SAC code actually exists in the official list, and shows you the description of the goods or services it covers. It tells you if a code is valid before you put it on a GST invoice or return. This page works as a free HSN code validator — no login needed.

How do I validate an HSN code?

Enter the code in the search box above. If it is a valid HSN/SAC code, the tool returns it along with its official description. Then confirm that description matches what you actually sell — a code can exist and still be the wrong one for your product, which is what causes the wrong GST rate.

Is there a free HSN code checker?

Yes — this tool is a free HSN code checker. Type an HSN or SAC code (or part of a product name) and it checks it against the official list instantly. There is no signup and no limit on how many codes you check.

How do I check if an HSN code is correct or wrong?

Search the code above and read the description that comes back. If no result appears, the code is not valid. If a result appears but the description does not match your product, the code is wrong for you — search by product name instead to find the correct one.

Can I verify HSN codes in bulk?

The tool checks one code or keyword at a time, which suits most small businesses. If you need to verify HSN codes across a whole item list, KhataBuddy applies and stores the correct HSN/SAC code and GST rate against every item in your catalogue, so your codes stay right on every invoice without re-checking them one by one.

HSN Code Validator — check whether an HSN code is valid

Use the tool above as an HSN code validator. Type the HSN or SAC code you want to validate and it is matched against the official HSN/SAC list. If the code exists, you get its official description — if nothing comes back, the code isn’t valid and needs correcting before you bill.

Confirming the description matches what you actually sell is the real check. A code can exist and still be the wrong code for your product, which is what leads to the wrong GST rate and mismatches in your returns.

How to validate an HSN code in 3 steps

Enter the HSN/SAC code in the search box above.
Check that a matching code is returned from the official list.
Confirm the description matches your product or service.

The same box works as an HSN code checker and SAC code checker — you can check a code you already have, or search by product name to find the right one in the first place.

What are HSN and SAC codes?

HSN (Harmonized System of Nomenclature) codes are used to classify goods under GST, while SAC (Services Accounting Code) codes classify services. Putting the correct code on your invoices and GST returns ensures the right tax rate is applied and keeps you compliant.

The number of digits you need depends on your turnover — typically 4 digits up to ₹5 crore and 6 digits above it, with 8 digits for imports and exports. Use the finder above to search the official HSN/SAC list by keyword or code.

You can also use it to verify or check an HSN code you already have — just search the number and confirm the description matches your product before adding it to a GST invoice or return.

Tip

Inside KhataBuddy, the right HSN/SAC code and GST rate are suggested automatically as you add items — so you never have to look them up manually again.
