Dhanteras 2026 saw significant demand for gold and silver, even as prices on the Multi Commodity Exchange (MCX) saw a decline. On Friday, November 6, 2026, MCX December gold futures fell 1.45% to approximately ₹1.42 lakh per 10 grams, while December silver futures slipped 1.65% to ₹1.84 lakh per kilogram. For consumers purchasing jewellery on this auspicious occasion, verifying the Hallmark Unique Identification (HUID) number is crucial to guarantee purity and authenticity.
The Bureau of Indian Standards (BIS) has implemented a robust digital verification system, allowing buyers to check hallmarking details via their smartphones. As of October 15, 2026, over 65 crore gold articles had received HUID numbers, reflecting the widespread adoption of this system. The number of BIS-registered jewellers has also grown significantly, from 43,153 in 2021 to 2,36,624, indicating a robust hallmarking ecosystem in India.
Understanding the HUID System for Gold Purity
The HUID system is designed to provide transparency and build consumer trust in gold purchases. It serves as a digital fingerprint for each piece of hallmarked jewellery.
What is HUID?
HUID is a unique six-digit alphanumeric identification code assigned to every piece of hallmarked jewellery. This code enables consumers to verify the article's recorded purity and other hallmarking details, ensuring that the jewellery meets the declared standards.
Key Hallmarking Marks
Every hallmarked gold ornament should visibly display three essential identification marks:
- BIS Logo: This symbol confirms that the article has been officially hallmarked by the Bureau of Indian Standards.
- Purity Mark: This indicates the gold's purity level, such as '22K916' for 22-karat gold, signifying 91.6% purity.
- HUID Number: The unique six-digit alphanumeric code that identifies the specific article.
How to Verify Gold HUID Number Using the BIS Care App
Consumers can easily check their jewellery details through the free BIS Care app, available for both Android and iOS devices, before finalizing a purchase.
- Download the App: Get the BIS Care app from the Google Play Store or Apple App Store.
- Open and Select: Launch the application and choose the 'Verify HUID' option from the main menu.
- Enter HUID: Carefully input the six-digit alphanumeric HUID code that is engraved on the jewellery item.
- Submit for Details: Submit the entered code to retrieve all the associated hallmarking information for the article.
- Compare Information: Cross-reference the displayed purity, jewellery description, jeweller details, and assaying centre information with the physical ornament. The app may also provide photographs, hallmark images, recorded weight, and testing specifics, depending on the available record.
What to Do if HUID Details Don't Match
If the information displayed on the BIS Care app—such as purity, article description, or jeweller details—does not align with the physical jewellery, buyers should immediately seek clarification from the jeweller. If discrepancies persist or remain unresolved, consumers have the option to raise a complaint directly through the BIS Care app.
Hallmarking for Silver Jewellery
While hallmarking for silver jewellery remains voluntary, HUID identification became mandatory for all hallmarked silver articles starting September 1, 2025. As of late 2026, over 90 lakh silver articles have already received HUID numbers. For Dhanteras buyers, checking these hallmark details provides an essential safeguard against potential purity-related discrepancies, particularly when investing in valuable jewellery.
