How to Verify BIS Hallmarked Gold Online: The 6-Digit HUID Code Guide
01.Understanding the HUID Security System
To prevent carat manipulation and counterfeit stamping, the Bureau of Indian Standards mandated **Hallmark Unique Identification (HUID)** numbers.
A HUID code is an exclusive **6-digit alphanumeric identifier** laser-engraved onto each precious metal piece at an authorized Assaying & Hallmarking Centre (AHC). The identifier is registered in the central BIS database prior to market distribution.
02.The Three Mandatory BIS Hallmark Marks
Under current Indian standards, verified hallmarked gold exhibits three distinct laser-engraved marks:
| Symbol | Identification Component | Verification Significance |
|---|---|---|
| BIS Logo | Triangular Standard Mark | Certifies conformity to Bureau of Indian Standards specifications. |
| Purity Mark | Fineness Number (e.g. 24K999 or 22K916) | Identifies the precise proportion of pure gold per thousand parts. |
| 6-Digit HUID | Alphanumeric Code (e.g. AB1234) | Unique database tracking code linking the item to its assaying facility and timestamp. |
03.Step-by-Step Verification Using the BIS Care App
Authentication requires four steps using a standard smartphone:
1. **Install Application**: Download the official **BIS Care App** published by the Bureau of Indian Standards from the Google Play Store or Apple App Store. 2. **Access Verification Tool**: Navigate to the **"Verify HUID"** module on the main interface. 3. **Input Code**: Enter the 6-character alphanumeric code engraved on the metal or printed on your tax invoice. 4. **Review Registry Data**: The registry will display: - Assaying & Hallmarking Centre (AHC) registration code - Article classification (Coin, Bar, Pendant) - Certified purity (24K - 999.9) - Date of hallmarking
The details retrieved from the registry must match the physical item and tax invoice.
