How to Verify BIS Hallmark Online in India—Complete Step-by-Step Guide

You are about to spend ₹15,000 or ₹1.5 lakh on a piece of gold jewelry. The design is beautiful. The price feels right. But here is the one question most people forget to ask—is it actually real gold?

You can know for certain in under two minutes. All you need is your phone.

What Is BIS Hallmark and Why Does It Matter?

BIS stands for Bureau of Indian Standards — India's national standards body, operating under the Ministry of Consumer Affairs.

A BIS hallmark on gold jewelry means the piece has been independently tested and certified for gold purity at a BIS-licensed Assaying and Hallmarking Centre.

Since 2021, BIS hallmarking is mandatory for all gold jewelry sold in India. Any seller offering gold jewelry without a hallmark is either selling old stock — or selling something that is not real gold at the purity they claim.

Without a BIS hallmark, there is no independent proof of what gold purity you are actually getting. The seller's word alone is not enough. The hallmark is the only government-backed assurance that what you paid for is exactly what you received.

What the BIS Stamp on Your Jewelry Actually Means

A properly hallmarked piece of gold jewelry carries a tiny laser-engraved stamp. Once you know what to look for, it takes seconds to read. Use your phone's camera zoom if needed.

The stamp has three parts:

1. The BIS Logo A triangular mark with "BIS" inside. This confirms the piece was tested at a BIS-certified hallmarking centre — not just claimed by the seller.

2. The Purity Number A 3-digit number showing gold purity in parts per thousand:

• 375 = 9K gold

• 417 = 10K gold

• 585 = 14K gold

• 750 = 18K gold

3. The HUID Code A unique 6-digit alphanumeric code assigned to this specific piece—and only this piece. This is what you enter into the BIS Care app to verify authenticity.

What Is the HUID Code?

HUID stands for Hallmark Unique Identification.

The old hallmarking system had a gap — it only proved that a batch of jewelry was tested, not the individual piece. HUID closed that gap completely.

Every hallmarked gold piece now has its own unique 6-digit code, laser-engraved directly onto the metal. No two pieces share the same HUID. This makes it almost impossible to fake the stamp by copying it from a genuine piece onto an untested one.

Where to find it:

• Inside the band of a ring

• On the clasp of a bracelet

• On the post of an earring

• On the back of a pendant
  

If you cannot find it, ask the seller to show you with a magnifying glass. Any legitimate seller will have no problem doing this. A quick note on small jewelry pieces: hallmark stamps on delicate and lightweight jewelry are naturally tiny. On very fine pieces, you may find just the karat mark — 9K, 10K, 14K, or 18K — stamped on the metal. This is completely normal and is recognized under BIS guidelines. The karat mark alone tells you exactly what you need to know about your gold.

How to Verify Using the BIS Care App—Step by Step

The BIS Care app is the official government-backed verification tool. It is free, available in multiple languages, and works on both Android and iOS.

Step 1 — Download the BIS Care App

Search "BIS Care" on Google Play Store or Apple App Store. Download and open it. It is completely free.

Step 2 — Register with Your Mobile Number

Log in using your mobile number via OTP. This takes under a minute and is required only once.

Step 3—Tap "Verify HUID"

On the home screen, tap the Verify HUID option. This is specifically built for verifying hallmarked gold and silver jewelry.

Step 4 — Find the HUID on Your Jewelry

Look for the 6-digit alphanumeric code engraved on the piece. Use your phone camera zoom if needed. It will look something like: A3F72B

Step 5 — Enter the Code and Tap Search

Type the code exactly as it appears on the jewelry. Tap Search. Results appear within seconds.

Step 6 — Match What You See With What You Bought

The app shows:

• Gold purity

• The hallmarking centre that tested the piece

• Jeweler registration details

• Date of hallmarking
  

If these details match your piece — your jewelry is genuine.

Buying online? You cannot verify the HUID before delivery since the piece has not arrived yet. Once it does, follow the steps above immediately. If the HUID does not appear in the app or the details do not match — that is a serious red flag.

Gold Purity Levels—What 375, 417, 585, and 750 Actually Mean

The purity number on your hallmark stamp tells you exactly how much of your jewelry is real gold.

Purity	Karat	Pure Gold	Best For
375	9K	37.5%	Most durable, most affordable — ideal entry point for everyday jewelry
417	10K	41.7%	Strong and scratch-resistant — great for active daily wear
585	14K	58.5%	Best balance of durability and purity — the most popular choice for fine jewelry
750	18K	75%	Richest gold color, highest purity — premium everyday and gifting pieces

All four are solid gold — none are plated or filled. The only difference is how much of the metal is pure gold. Higher karat means more gold, richer color, and slightly softer. Lower karat means more durable and more affordable.

Buying Gold Jewelry Online — What to Check Before You Order

Is BIS hallmarking clearly mentioned?

Legitimate sellers display this prominently. If you cannot find it anywhere on the website, that is a warning sign.

Is the karat stated clearly?

The listing must say 9K, 10K, 14K, or 18K solid gold — not just "gold" or "gold tone."

Are the gemstones natural or synthetic?

Natural, lab-grown, and synthetic (glass) are three entirely different things. A transparent seller always tells you exactly which one you are getting before you pay.

Will you receive a proper invoice?

A legitimate jewelry seller provides a bill with full metal details, stone details, and GST included. No invoice is a red flag.

Does the price make sense?

If "solid gold" earrings are priced at ₹500, they are not solid gold. Check the MCX gold rate as a rough reference point before buying.
