HUID and Hallmark Verification: Step-by-Step Guide for Kerala Buyers

Purity verification is an important step when purchasing gold jewellery. In India, the Bureau of Indian Standards (BIS) has introduced the Hallmark Unique Identification (HUID) system. This guide explains how to read and verify these markings to ensure the authenticity of your purchase.

What is HUID?

HUID is a unique 6-digit alphanumeric code laser-stamped onto every certified piece of gold jewellery at government-approved assaying centers. - Traceability: Each code is unique to an individual ornament, allowing you to trace it back to the manufacturer, assaying center, and purity test date. - Fraud Prevention: The system helps prevent the reuse of hallmark stamps on uncertified jewellery.

The Three Mandatory Marks

Since April 2023, all hallmarked gold ornaments in India must carry three specific marks:

1. BIS Logo: The official triangular mark of the Bureau of Indian Standards.
2. Purity Grade: Indicates the purity level of the gold:
3. - 22K916: 22 Karat (91.6% purity)
4. - 18K750: 18 Karat (75.0% purity)
5. - 14K585: 14 Karat (58.5% purity)
6. HUID Code: A 6-digit alphanumeric code (e.g., A1B2C3).

How to Verify HUID Using the BIS Care App

You can verify your gold's HUID code using the official government app:

1. Download the App: Search for the official "BIS Care" app on the Google Play Store or Apple App Store.
2. Access HUID Verification: Open the app and tap "Verify HUID".
3. Enter the Code: Type the 6-digit HUID code stamped on your ornament and tap search.
4. Review Registry Details: The app will display:
5. - Jeweller's registration name.
6. - Assaying center details.
7. - Purity grade and ornament type.
8. - Date of hallmarking.

Verify that the details on the app match the ornament you are purchasing.

Key Buying Tips

• Request a Purity Loupe: Showrooms have magnifying loupes. Ask to view the HUID stamp through the lens before finalizing your purchase.
• Check the Invoice: Ensure the HUID code is printed on your purchase bill, as this is required for future resale or exchange.
• Track Market Prices: Purity verification ensures quality, while checking daily rates on RateTracker.in to ensure you pay the correct market price.
