How to Verify HUID Number Online: Complete Step-by-Step Guide (2026)

Every piece of hallmarked gold jewellery sold in India since July 2021 carries a unique six-digit alphanumeric code called the Hallmark Unique Identification (HUID) number. This tiny code, laser-engraved or stamped onto your gold ornament, is your strongest weapon against gold fraud. Yet millions of Indian consumers purchase gold jewellery without ever verifying their HUID, leaving themselves vulnerable to counterfeit hallmarks and purity misrepresentation.

In this comprehensive guide, we walk you through every method of verifying your HUID number online, explain exactly what information the BIS database reveals, and show you what to do if your verification fails. Whether you purchased a simple gold chain from a local jeweller in Jaipur or an elaborate bridal set from a showroom in Mumbai, this guide will help you confirm that your gold is exactly what you paid for.

What Is a HUID Number and Why Does It Matter?

The Hallmark Unique Identification (HUID) number is a six-character alphanumeric code assigned by the Bureau of Indian Standards (BIS) to every individual piece of hallmarked gold jewellery. Introduced as part of the mandatory hallmarking regime that took effect on 23 June 2021, the HUID system replaced the older hallmarking format that included the jeweller's identification mark, the BIS Standard Mark, the purity grade, and the Assaying and Hallmarking Centre (AHC) mark.

The Old Hallmark vs the New HUID System

Under the old system, a dishonest jeweller could stamp a convincing-looking hallmark onto substandard gold, and the average consumer had no way to verify authenticity without visiting an assay centre. The HUID system changed everything by creating a centralised database where every hallmarked article is registered with its purity, weight, jeweller details, and the assay centre that tested it.

What Information Is Encoded in the HUID

When you verify a HUID number, the BIS database returns the following details:

• Article description (ring, chain, bangle, necklace, etc.)
• Purity grade (22K 916, 18K 750, 14K 585, or 24K 999)
• Gross weight at the time of hallmarking
• Name and registration number of the jeweller who submitted the article for hallmarking
• Assaying and Hallmarking Centre (AHC) that tested and certified the article
• Date of hallmarking
• BIS Standard (IS 1417 for gold jewellery)

This information allows you to cross-check everything the jeweller told you at the time of purchase. If the jeweller sold you a ring described as 22K gold weighing 8 grams, the HUID verification should show purity as 916 and weight in the vicinity of 8 grams (minor weight differences can occur due to polishing or stone setting after hallmarking).

Step-by-Step: Verify HUID on the BIS Website

The most straightforward method for verifying your HUID is through the official BIS verification portal. Here is exactly how to do it.

Step 1: Navigate to the BIS Verification Portal

Open your web browser and go to https://verify.bis.gov.in. This is the official Bureau of Indian Standards verification website. Make sure you are on the correct domain — fraudulent websites sometimes mimic the BIS portal to collect personal information.

Step 2: Select the Verification Type

On the homepage, you will see several verification options including licence verification, registration verification, and HUID verification. Click on "Verify HUID" or navigate to the HUID verification section. The portal may update its interface periodically, but the HUID verification option is always prominently displayed.

Step 3: Enter Your HUID Number

In the HUID field, type the six-character alphanumeric code exactly as it appears on your jewellery. The HUID is typically laser-engraved on the inside surface of rings, the clasp area of chains and necklaces, or the inner surface of bangles. You may need a magnifying glass to read it clearly.

Common input mistakes to avoid:

• Confusing the letter O with the number 0
• Confusing the letter I with the number 1
• Missing a character (ensure you have exactly six characters)
• Entering spaces between characters

Step 4: Complete the CAPTCHA

The website will display a CAPTCHA verification to confirm you are a human user. Enter the characters shown in the image. If the CAPTCHA is unclear, click the refresh button to generate a new one.

Step 5: Click Verify and Review Results

Click the "Verify" or "Search" button. The system will query the BIS database and display the hallmarking details associated with that HUID. Compare the information shown on screen with what the jeweller told you and what is printed on your purchase invoice.

What a Successful Verification Looks Like

A successful HUID verification will display a result page showing all the registered details. Here is an example of what you might see:

Step-by-Step: Verify HUID Using the BIS CARE App

The BIS CARE (Conformity Assessment, Recognition, and Enablement) mobile application provides an even more convenient way to verify your HUID, especially when you are at a jewellery store and want to check before purchasing.

Downloading the App

The BIS CARE app is available free of charge on both major mobile platforms:

• Android: Search "BIS CARE" on the Google Play Store
• iOS: Search "BIS CARE" on the Apple App Store

Ensure you download the official app published by the Bureau of Indian Standards. As of April 2026, the app has been downloaded over 5 million times on Android alone.

Verifying via Manual Entry

1. Open the BIS CARE app

2. Tap on "HUID Verification" from the main menu

3. Enter the six-character HUID code in the text field

4. Tap "Verify"

5. Review the displayed results

Verifying via QR Code Scan

Some newer hallmarked articles include a tiny QR code alongside the HUID. If your jewellery has a QR code:

1. Open the BIS CARE app

2. Tap on "Scan QR" or the camera icon

3. Point your phone camera at the QR code on the jewellery

4. The app will automatically read the HUID and display verification results

Filing a Complaint Through the App

One of the most powerful features of the BIS CARE app is the ability to file a complaint directly if you discover that your jewellery's HUID is invalid or the details do not match. The complaint goes directly to BIS, which has the authority to investigate and take action against non-compliant jewellers.

What to Do If HUID Verification Fails

Verification failure can occur for several reasons, and not all of them indicate fraud. Here is a systematic approach to handling a failed HUID verification.

Reason 1: Misread HUID Characters

The most common reason for verification failure is simply misreading the tiny engraved characters. Use a jeweller's loupe (10x magnification) or a high-quality magnifying glass to read the HUID carefully. Take a clear photograph with your smartphone camera using macro mode, then zoom in to identify each character.

Reason 2: Database Sync Delay

Occasionally, particularly for very recently hallmarked articles, there can be a delay of 24 to 48 hours between the physical hallmarking and the database update. If you purchased a piece that was hallmarked the same day, wait a day and try again.

Reason 3: Worn or Damaged Engraving

On jewellery that has been worn for several years, the laser engraving can wear down, making characters difficult to read. If this is the case, visit a BIS-recognised Assaying and Hallmarking Centre where they can help identify the HUID using specialised equipment.

Reason 4: Fake or Counterfeit HUID

If the HUID returns no result despite multiple careful attempts, or if the returned details do not match your jewellery at all (different article type, vastly different weight, different purity), you may have a counterfeit HUID. In this case:

1. Document everything: Take clear photographs of the jewellery, the hallmark, your purchase invoice, and the failed verification screen

2. Contact the jeweller first: Visit the store with your documentation and ask for an explanation. Legitimate jewellers will typically offer to get the article re-tested

3. File a complaint with BIS: Use the BIS CARE app or email hallmarking@bis.gov.in with your complaint and documentation

4. File a complaint on the National Consumer Helpline: Call 1800-11-4000 or visit consumerhelpline.gov.in

5. File a police complaint: If the jeweller is uncooperative and you believe fraud has occurred, file an FIR at your local police station

6. Approach the Consumer Forum: For financial recovery, you can file a case in the District Consumer Disputes Redressal Forum

Detecting Fake HUIDs: Advanced Techniques

Sophisticated counterfeiters have attempted to game the HUID system in various ways. Understanding their methods helps you stay protected.

Method 1: Reusing Valid HUIDs

Some dishonest jewellers stamp a genuine HUID from one article onto multiple pieces. To detect this, verify the HUID and check whether the article description and weight match your jewellery. If the database says "Men's Chain, 45 grams" but you purchased a "Ladies Ring, 6 grams," the HUID has been duplicated.

Method 2: Random Alphanumeric Codes

Some counterfeiters simply stamp random six-character codes that look like HUIDs but are not registered in the BIS database. These will return "No Record Found" when verified online.

Method 3: Partial Hallmark Forgery

In this method, the jewellery carries some genuine hallmark elements alongside a fake HUID. The BIS triangle logo might look authentic, but the HUID is either non-existent or copied from another article.

Verification Cross-Check Checklist

Understanding the Physical Hallmark on Your Jewellery

Since April 2023, the hallmark on gold jewellery in India consists of three marks arranged in a specific sequence:

Mark 1: BIS Standard Mark

The familiar triangular BIS logo indicates that the article has been tested by a BIS-recognised assay centre and meets the Indian Standard IS 1417 for gold jewellery.

Mark 2: Purity Grade

This indicates the fineness of the gold:

• 916 corresponds to 22 Karat (91.6% pure gold)
• 750 corresponds to 18 Karat (75.0% pure gold)
• 585 corresponds to 14 Karat (58.5% pure gold)
• 999 corresponds to 24 Karat (99.9% pure gold)

Mark 3: HUID Number

The six-character alphanumeric code that links to the BIS database. This is the mark you will use for online verification.

Where to Find the Hallmark on Different Jewellery Types

Real-World HUID Verification Examples

Example 1: Priya's Wedding Necklace from Mumbai

Priya Sharma purchased a 22K gold wedding necklace weighing 48 grams from a well-known jeweller in Zaveri Bazaar, Mumbai, for ₹3,26,400 in March 2026. She noticed the HUID engraved on the clasp area: K4N8P2. Using the BIS CARE app, she verified the HUID and found the following:

• Article: Necklace
• Purity: 916 (22K)
• Weight: 47.8 grams
• Jeweller: The same store she purchased from
• Date: 8 March 2026

The slight weight difference of 0.2 grams was explained by final polishing done after hallmarking. Everything matched, confirming her necklace was genuine.

Example 2: Ravi's Suspicious Gold Chain from Hyderabad

Ravi Kumar bought a gold chain described as 22K weighing 25 grams from a small jeweller in Hyderabad for ₹1,62,500. When he tried to verify the HUID X3M7Q1 on the BIS website, the database showed:

• Article: Ladies Bangle
• Purity: 750 (18K)
• Weight: 15.2 grams
• Jeweller: A different shop in Chennai

Every detail was wrong. The HUID had clearly been copied from another article. Ravi filed a complaint through the BIS CARE app and approached the Consumer Forum, eventually receiving a full refund plus ₹25,000 in compensation.

Example 3: Meena's Antique-Style Bangles from Jaipur

Meena Devi purchased a pair of antique-finish bangles from a heritage jeweller in Jaipur for ₹1,85,000. She could not find any HUID on the bangles. The jeweller explained that the articles were made before the mandatory hallmarking deadline and were therefore exempt. However, Meena checked her invoice, which was dated February 2026 — well after the mandate. She reported the matter to BIS, and the jeweller was subsequently found to be selling unhallmarked jewellery and penalised ₹1,00,000.

The Legal Framework Behind HUID Verification

BIS Act 2016 and Hallmarking Orders

The Bureau of Indian Standards Act, 2016 provides the legal foundation for mandatory hallmarking in India. Under Section 14 of the Act, the Central Government has the power to mandate hallmarking for articles of precious metals in the public interest. The Hallmarking of Gold Jewellery and Gold Artefacts Order, 2020 (amended in 2021) made hallmarking compulsory across India in a phased manner.

Penalties for Non-Compliance

Consumer Rights Under the Hallmarking Regime

As a consumer, you have the legal right to:

• Demand hallmarked jewellery from any registered jeweller
• Verify the HUID of any hallmarked article at any time
• File a complaint with BIS if verification fails or details mismatch
• Seek compensation through Consumer Forums for purity fraud
• Demand a re-test at any BIS-recognised Assaying and Hallmarking Centre

Cost of Getting Jewellery Independently Tested

If you want additional assurance beyond HUID verification, you can get your gold jewellery independently tested at a BIS-recognised Assaying and Hallmarking Centre.

The XRF (X-ray fluorescence) test is non-destructive, meaning it does not damage your jewellery. Fire assay is more accurate but requires removing a small sample from the article. For routine verification, XRF testing is usually sufficient.

Tips for Ensuring HUID Authenticity at the Time of Purchase

Prevention is always better than cure. Follow these practices every time you buy gold jewellery:

1. Verify before paying: Ask the jeweller to show you the HUID on the article and verify it on the BIS CARE app while still at the store

2. Check the invoice: Ensure the HUID number is printed on your purchase invoice alongside the weight, purity, making charges, and GST details

3. Compare weights: The weight on the invoice should closely match the weight shown in the HUID database

4. Photograph the hallmark: Take a clear macro photograph of the hallmark area for your records

5. Buy from BIS-registered jewellers: Use the BIS website to confirm that the jeweller holds a valid registration. You can search registered jewellers on our store finder page

6. Keep all documentation: Store your invoice, HUID verification screenshots, and any certificates in a safe place

7. Verify periodically: If you have older jewellery purchased since 2021, verify those HUIDs as well — it is never too late to check

Frequently Asked Questions

1. What does HUID stand for?

HUID stands for Hallmark Unique Identification. It is a six-character alphanumeric code assigned by the Bureau of Indian Standards to each individually hallmarked piece of gold jewellery sold in India. The code links to a centralised database containing the article's purity, weight, jeweller details, and assay centre information.

2. Is HUID mandatory on all gold jewellery in India?

Yes, since the phased rollout that began on 23 June 2021 and was extended nationwide, HUID is mandatory on all gold jewellery sold by BIS-registered jewellers. As of April 2026, all districts across India are covered under mandatory hallmarking. Jewellers selling unhallmarked gold jewellery face fines of up to ₹1,00,000.

3. Can I verify HUID without the internet?

No, HUID verification requires an active internet connection because the verification system queries the centralised BIS database in real time. You need either a web browser to access verify.bis.gov.in or the BIS CARE mobile app with a data connection.

4. What should I do if the HUID on my jewellery does not show any result online?

First, double-check that you have read the HUID characters correctly using a magnifying glass. If the HUID still shows no result, wait 48 hours and try again in case of a database sync delay. If it still fails, contact BIS at hallmarking@bis.gov.in or through the BIS CARE app's complaint feature. Also approach the jeweller with your invoice and documentation.

5. Can two pieces of jewellery have the same HUID?

No, each HUID is unique to a single article. If you find the same HUID on two different pieces, one of them is counterfeit. Report this to BIS immediately. Legitimate hallmarking centres generate unique HUIDs from the BIS server for each individual article.

6. Does HUID apply to gold coins and bars?

HUID and mandatory hallmarking apply to gold jewellery and gold artefacts. Gold coins and bars have separate standards and are typically sold with assay certificates rather than HUID hallmarks. However, gold coins sold as jewellery items by BIS-registered jewellers may carry HUID if hallmarked.

7. How much does it cost to verify HUID?

HUID verification is completely free. Both the BIS website (verify.bis.gov.in) and the BIS CARE mobile app allow unlimited free verifications. You do not need to create an account or pay any fee.

8. Is the BIS CARE app safe to use?

Yes, the BIS CARE app is an official government application published by the Bureau of Indian Standards. It does not require sensitive personal information for HUID verification. Ensure you download it from the official Google Play Store or Apple App Store to avoid fake versions.

9. Can a jeweller refuse to show me the HUID on jewellery before purchase?

No, a jeweller cannot legally refuse to show you the hallmark and HUID. Under the BIS mandatory hallmarking rules, all hallmarked jewellery must have the HUID visible and verifiable. If a jeweller refuses, this is a red flag and you should consider purchasing elsewhere. Use our jeweller directory to find verified, BIS-registered jewellers near you.

10. What is the difference between BIS registration and hallmarking?

BIS registration refers to the jeweller being registered with the Bureau of Indian Standards as an authorised seller of hallmarked jewellery. Hallmarking refers to the testing and certification of individual pieces of jewellery by a BIS-recognised Assaying and Hallmarking Centre. A jeweller must have BIS registration to submit articles for hallmarking.

11. My gold jewellery was purchased before 2021. Does it have a HUID?

Gold jewellery purchased before the mandatory hallmarking regime (23 June 2021) will not have a HUID. Older hallmarked jewellery carries the previous four-mark hallmark format (BIS logo, purity, jeweller's mark, AHC mark) without a HUID. This jewellery is still valid but cannot be verified online through the HUID system. If you wish, you can get it re-hallmarked with a HUID at any recognised AHC for ₹45 per article.

12. Can I track where my gold was sourced using the HUID?

The HUID system tracks the jeweller who submitted the article for hallmarking and the assay centre that tested it. However, it does not currently track the upstream gold supply chain (refiner, mine, etc.). For full supply chain traceability, some premium jewellers are adopting blockchain-based provenance systems, which we cover in our blockchain authentication guide.
