When you buy gold jewellery, one question always matters most: is this gold real and pure? The HUID code answers that question directly. Every piece of BIS-hallmarked gold jewellery in India now carries a unique 6-digit alphanumeric HUID code that links it to a government-verified database. You can check this code online in seconds and confirm the purity, carat, and jeweller details of your gold. If your jewellery does not have this code, you have no way to verify its authenticity through official channels.
What Is HUID Code in Gold Jewellery?
HUID stands for Hallmarking Unique Identification. It is a 6-digit alphanumeric code that the Bureau of Indian Standards (BIS) assigns to every individual piece of hallmarked gold jewellery in India. No two pieces share the same HUID, which makes it a reliable identity marker for your gold.
The Government of India made HUID-based hallmarking mandatory in 2021. Before this system, hallmarks only confirmed purity at a batch level. With HUID, every single piece gets its own traceable identity. This shift gave buyers a direct way to verify their gold jewellery for women and gold jewellery for men without depending solely on the word of the jeweller.
The 6-digit code gets laser-engraved or stamped onto the jewellery along with the BIS logo, the purity grade (such as 916 for 22K gold), and the assaying centre’s mark. Together, these four elements form a complete BIS hallmark.
What Does the 6-Digit HUID Code Tell You?
Each HUID code connects to a record in the BIS database that stores the following details:
- The name and registration number of the jeweller who sold the piece
- The assaying and hallmarking centre that tested and certified it
- The metal type (gold, silver, or other)
- The purity grade (14K, 18K, 22K, etc.)
- The date of hallmarking
This makes the HUID code more than a label. It is a traceable certificate embedded directly into the jewellery. Whether you are buying gold jewellery for women as a bridal set or picking up gold jewellery for men as a daily-wear chain, the HUID tells you everything the piece has been through before it reached you.
How to Check HUID Code Online
Checking a HUID code online takes less than a minute. The BIS has a dedicated portal called BIS Care where anyone can verify a hallmark for free.
Here is how you do it step by step:
- Go to the official BIS Care website at bis.gov.in or download the BIS Care app from the Google Play Store or Apple App Store
- Look for the option labelled “Verify HUID” or “Hallmark Verification”
- Enter the 6-digit HUID code printed or engraved on your jewellery
- Click on “Verify” or “Search”
- The portal displays the registered details linked to that code, including the jeweller name, purity, metal type, and hallmarking centre
If the code returns a valid result, your jewellery is government-certified and genuine. If the portal shows no record or an error, the hallmark may be fake or incorrectly entered.
Always check the HUID at the time of purchase itself. Do not wait until later. Jewellers are legally required to give you a receipt that includes the HUID code, so you have a reference even after you leave the store.
How to Identify the HUID Number on Jewellery
Finding the HUID on a piece of jewellery requires looking in the right place. On rings, the code usually appears on the inner surface of the band. In necklaces and chains, look near the clasp or on a small tag attached to the piece. On bangles and kadas, the code sits on the inner flat surface.
The HUID is typically very small and may require a magnifying glass to read clearly. It appears as a combination of letters and numbers, such as AB1234 or X7K9P2. Alongside it, you should see the BIS logo (a triangle with BIS written inside), the purity mark (like 916 for 22K), and the assaying centre’s code.
If you struggle to find the code, ask the jeweller to point it out before you complete the purchase. A legitimate jeweller will have no hesitation showing it to you.
BIS Hallmark vs HUID: What Is the Difference?
Many buyers confuse BIS hallmark with HUID, but the two are not the same thing. Understanding the difference protects you from accepting outdated or incomplete certification.
| Feature | BIS Hallmark (Old System) | BIS HUID (New System) |
|---|---|---|
| Introduced | 2000 | 2021 |
| Unique per piece | No | Yes |
| Online verification | Not possible | Available on BIS Care |
| Traceability | Batch level | Individual piece level |
| Digits | No unique code | 6-digit alphanumeric |
| Mandatory | No | Yes (from 2021) |
The old hallmark system used symbols to indicate purity but offered no way to trace individual pieces. HUID upgrades this by giving every piece a distinct identity that links back to a government record. If your older jewellery does not have a HUID, it may still carry a valid BIS hallmark from the previous system, but you cannot verify it online through the current portal.
What If There Is No HUID Number on Your Gold?
If a piece of gold jewellery has no HUID code, there are a few possible explanations. The jewellery may have been made and sold before the HUID mandate came into effect in 2021. It may also be imported jewellery that was not hallmarked under the Indian BIS system. In rare cases, it could indicate that the piece was never officially hallmarked at all.
Here is what you should do if you find no HUID:
- Ask the jeweller directly why the HUID is missing and request documentation
- Check if the piece carries the older BIS hallmark symbols without a 6-digit code
- Send the jewellery to a BIS-approved assaying centre for independent purity testing
- Do not accept a verbal assurance of purity without some form of verifiable documentation
For any gold bought after September 2021, the absence of a HUID is a serious red flag. Jewellers in India are legally required to sell only HUID-hallmarked gold under BIS regulations. If a jeweller cannot provide a HUID on new jewellery, you should question the source and quality of that gold before making any payment.
Why HUID Matters When Reselling Gold
The HUID code does not just protect you at the time of purchase. It also plays a major role when you resell or exchange your gold in the future. Jewellers and gold buyers increasingly rely on HUID verification to determine the buy-back price of a piece. A verified HUID means the purity is confirmed, which reduces negotiation friction and often leads to better resale value.
Without a HUID, a reseller may apply a purity deduction because they cannot independently verify what you are claiming. This can reduce your effective return on the gold even if it is genuinely pure. Keeping the original receipt with the HUID code alongside your jewellery ensures a smoother and more profitable resale process later.

Final Thoughts
The HUID code in gold jewellery is not a bureaucratic formality. It is your clearest proof that the gold you paid for is exactly what the jeweller claimed it to be. In a market where gold prices are high and purity disputes are common, a 6-digit code verified on a government portal gives you something no verbal promise can: certainty. Always check the HUID before paying, keep your receipt, and use the BIS Care app whenever you have doubts. Whether you are buying a lightweight everyday piece or a heavy bridal set, HUID verification takes sixty seconds and can save you from losing thousands of rupees to fraud.
