A BIS hallmark isn’t decoration — it’s the only nationally regulated proof that the gold you’re buying is actually the purity it’s claimed to be. If you’ve read our guides on choosing a jeweller in Varanasi or buying gold jewellery here, you already know hallmarking matters. This piece goes one level deeper: what BIS hallmarked jewellery actually certifies, how the system became mandatory, and exactly how to use it to protect a purchase.
We’ll cover what the three hallmark marks mean, the history behind India’s hallmarking system, how to verify a piece before and after you buy it, and what recourse you have if a hallmark turns out to be fake. For a full jeweller-selection checklist, see our guide on choosing a trusted jeweller in Varanasi; for a deep dive into karats and purity grades, see our guide to buying gold jewellery in Varanasi. This piece is entirely about the hallmark itself.
What Is BIS Hallmarking, Exactly?
BIS hallmarking is a government-regulated certification system, administered by the Bureau of Indian Standards under the Ministry of Consumer Affairs, that verifies the purity of gold and silver jewellery against the national standard, IS 1417:2016. In plain terms, it’s an independent, third-party guarantee — not the jeweller’s own claim — that a piece is exactly as pure as it says it is.
A genuine BIS hallmark carries three elements together: the BIS triangle logo (the mark of the regulator itself), the purity or fineness grade (such as 916 for 22-karat gold), and a unique 6-digit HUID — Hallmark Unique Identification — code that ties the piece to a specific test record. Without all three present together, what you’re looking at isn’t a complete, verifiable hallmark, whatever else might be stamped on the piece.
A Brief History: From Voluntary Mark to National Mandate
BIS hallmarking has existed far longer than most buyers realise. The scheme for gold was introduced in 2000, with a separate scheme for silver following in 2005 — both entirely voluntary for two decades. Jewellers could choose to get their gold certified as a quality signal, but nothing compelled them to, and enforcement had no teeth. That voluntary period wasn’t wasted, though: it built the network of Assaying and Hallmarking Centres (AHCs) and the administrative groundwork that made a rapid mandatory rollout possible later.
- 2000 — Gold hallmarking scheme launched (voluntary)
- 2005 — Silver hallmarking scheme launched (voluntary)
- 23 June 2021 — Mandatory hallmarking begins: 14K, 18K, and 22K gold, across 256 districts
- 2022 — Coverage expands to all six mandatory caratages (14K–24K)
- 6 September 2023 — 55 more districts added
- 5 November 2024 — 18 more districts added (361 total)
- 31 July 2025 — 12 more districts added (373 total)
- 1 September 2025 — Silver hallmarking becomes mandatory nationwide
- 2 March 2026 — 7 more districts added (380 total)
- 3 August 2026 — 12 more districts added (392 total, most recent expansion)
Varanasi has been covered since an early phase of this rollout. One detail worth correcting here, since outdated information circulates widely: 9-karat gold hallmarking remains voluntary under IS 1417:2016, not mandatory. The six mandatory caratages are 14K, 18K, 20K, 22K, 23K, and 24K. A jeweller can still choose to get 9K gold hallmarked, but isn’t legally required to the way they are for the other six grades.
The Problem Hallmarking Actually Solves
Before mandatory hallmarking, a buyer had essentially no independent way to confirm gold purity beyond trusting the seller’s word, or paying separately to have a piece tested. That gap is exactly what the mandatory system was built to close, and the scale of its adoption is a reasonable proxy for how seriously it’s been taken. Since the mandatory rollout began, more than 60 crore gold items have been hallmarked with a unique HUID, at a pace that’s grown from roughly 3 lakh items a day in 2022 to over 4 lakh a day by late 2024. The number of BIS-registered jewellers has grown from roughly 34,600 to more than 1.9 lakh over the same period, and the number of Assaying and Hallmarking Centres has grown from under 1,000 to over 1,600 nationwide.
None of that scale matters to you personally at the counter, of course — what matters is that it reflects a system built for volume and enforcement, not a symbolic gesture. A stamp that exists inside that kind of infrastructure is meaningfully different from an unregulated purity claim.
Reading a BIS Hallmark: The Three Marks Explained
Once you know what to look for, a hallmark takes seconds to read. The BIS triangle is the regulator’s own mark, confirming the piece was tested through the official system rather than self-certified by the seller. The fineness grade is the purity itself, written as a three-digit number — 916 for 22-karat gold, 750 for 18-karat, 833 for 20-karat, and so on — representing parts per thousand of pure gold. And the HUID is a unique 6-digit alphanumeric code assigned to that specific piece during testing, which is what actually lets you verify the other two claims independently.
For a full breakdown of what each karat and fineness number means, which caratage suits which use case, and where the stamp is physically located on different jewellery types, see our complete guide to buying gold jewellery in Varanasi. This piece focuses specifically on the certification system itself, not the purity math behind it.
How to Verify a BIS Hallmark Before You Buy
Verification happens on two levels, and most buyers only ever check the first. The piece-level check is the one most people know: open the BIS CARE app, enter the 6-digit HUID stamped on the jewellery, and the app returns the purity, the registered jeweller, and the assaying centre that tested it. If the code doesn’t exist in the database, the hallmark is fake, full stop.
The second, less-known level is checking the jeweller itself. BIS publishes a list of licensed jewellers registered under its Jewellers Registration Scheme, and a shop’s registration can be suspended or cancelled for violations — meaning a jeweller can, in theory, keep displaying old hallmark signage after losing the right to sell hallmarked gold. Asking directly whether a jeweller’s BIS registration is current, and checking that it matches the name on your bill, closes that gap. Our full guide to choosing a trusted jeweller in Varanasi walks through this and several other checks in detail.
What If You Already Own Unhallmarked Gold?
If you’ve inherited jewellery bought years before hallmarking existed, or before it applied in your area, you’re not without options. Any BIS-recognised Assaying and Hallmarking Centre will test gold jewellery brought in by an individual consumer, on a priority basis, for a fee, and issue a test report confirming its purity. That report doesn’t retroactively add a HUID to an old piece, but it does give you independent proof of purity if you ever want to sell, exchange, or insure it.
What Happens When a Hallmark Turns Out to Be Fake
The law backs the hallmark, not just the shop selling it. Under Rule 49 of the BIS (Hallmarking) Regulations, 2018, if a hallmarked piece later tests below its declared purity, you’re entitled to compensation equal to twice the value of the purity shortfall, plus testing charges, paid by the seller. Selling fake-hallmarked or non-compliant jewellery is an offence under the BIS Act, 2016, with penalties that include fines, licence suspension or cancellation, and prosecution in serious cases.
If you suspect a problem, you can complain directly to BIS through the BIS CARE app or by writing to complaints@bis.gov.in, call the National Consumer Helpline at 1800-11-4000, or file with your District Consumer Disputes Redressal Commission through the e-Daakhil portal. Our jeweller-selection guide covers this process in full, including exactly what documents to keep.
Common Misconceptions About BIS Hallmarking
- “No hallmark always means fake gold.” Not necessarily. Gold-plated, gold-filled, and artificial jewellery are never hallmarked, because hallmarking only certifies solid gold and silver — its absence there is expected, not evidence of fraud. See our gold jewellery guide for the full solid-vs-plated distinction.
- “A hallmark guarantees a fair price.” Hallmarking certifies purity only — it says nothing about making charges, design premiums, or overall value, which are separate questions worth asking about directly.
- “Old family jewellery without a hallmark must be fake.” Not necessarily. Jewellery bought before hallmarking applied in your area, or before the scheme existed at all, is simply unhallmarked, not fraudulent — and it can still be tested and certified now.
- “Once hallmarked, always guaranteed.” A hallmark certifies the piece as tested at that specific time. If it’s later melted down, reworked, or has metal added without re-testing, the original HUID no longer applies to the new piece — worth remembering for any reworked or custom bridal set.
Hallmarking Beyond Gold: Silver Too
Gold isn’t the only metal BIS regulates this way. Silver hallmarking existed on the same voluntary basis as gold, from 2005 onward, until it also became mandatory, from 1 September 2025. If you’re buying silver jewellery or artefacts alongside gold — increasingly common for lighter, everyday pieces — the same triangle-plus-purity-plus-HUID logic now applies there too.
Why This Matters Specifically in Varanasi
Varanasi sits within BIS’s mandatory hallmarking coverage, which means every gold jewellery shop here selling new jewellery is legally required to sell only hallmarked pieces across the six mandatory caratages. That’s not true everywhere in India even now — mandatory coverage has expanded to 392 districts as of August 2026, but hasn’t yet reached full national coverage. For Varanasi buyers, that means the checks in this guide aren’t optional extras; they’re standards every legitimate jeweller in the city is already required to meet, whether it’s a heritage family shop or a large showroom.
Frequently Asked Questions
What does a BIS hallmark on gold jewellery actually certify?
It certifies that the piece has been independently tested by a BIS-recognised Assaying and Hallmarking Centre and confirmed to match its stated purity, shown as a fineness number such as 916 for 22-karat gold, alongside a unique 6-digit HUID code.
Is 9-karat gold hallmarking mandatory in India?
No. Nine-karat gold hallmarking remains voluntary under IS 1417:2016. The six mandatory caratages are 14K, 18K, 20K, 22K, 23K, and 24K.
How do I check if a hallmark is genuine?
Enter the piece’s 6-digit HUID into the BIS CARE app. It will show the purity, the registered jeweller, and the assaying centre that tested it. If the code isn’t in the database, the hallmark isn’t genuine.
Can I get old, unhallmarked gold jewellery tested?
Yes. Any BIS-recognised Assaying and Hallmarking Centre will test jewellery brought in by an individual consumer, on a priority basis, for a fee, and provide a purity test report.
What can I do if I bought jewellery with a fake hallmark?
You’re entitled to compensation equal to twice the value of the purity shortfall plus testing charges under BIS Rule 49, and you can file a complaint through the BIS CARE app, complaints@bis.gov.in, the National Consumer Helpline (1800-11-4000), or your District Consumer Disputes Redressal Commission.
Is silver jewellery also required to carry a BIS hallmark?
Yes, since 1 September 2025. Silver hallmarking followed the same path as gold — voluntary from 2005, then made mandatory in 2025.
Does mandatory hallmarking apply everywhere in Varanasi?
Yes. Varanasi falls within BIS’s mandatory hallmarking coverage, so any shop selling new gold jewellery in the six mandatory caratages is legally required to sell only hallmarked pieces.
