1. Introduction to Hallmarking in India
Hallmarking is the government‑mandated system for certifying precious metal purity—in particular for gold jewellery and artefacts—and is overseen in India by the Bureau of Indian Standards (BIS). Hallmarked items are tested and marked for purity (e.g. 22 K=916 fineness), jeweller ID, BIS logo, and assay centre ID. This scheme became mandatory in stages: from June 23, 2021 in 256 districts, expanding to 288 by June 1, 2022. Six purity grades are standardized: 14 K, 18 K, 20 K, 22 K, 23 K, and 24 K under IS 1417 (2016) crackittoday.com+12BIS Services+12jjjewellersbhalla.com.
Until mid‑2021, hallmarked jewellery bore four marks—BIS logo, purity, jeweller mark, and assay centre mark. However, despite testing and marking, this system allowed duplicate hallmarking and made traceability difficult.
2. What Is the HUID System?
In response to limitations of the earlier hallmarking regime, the BIS introduced the Hallmark Unique Identification (HUID) system on July 1, 2021. Under this system each piece of gold jewellery is assigned a unique six‑digit alphanumeric code (called the HUID), generated centrally by BIS and laser‑etched on the jewellery—along with the BIS logo and purity mark. The jeweller and assay centre marks are no longer included BIS Services+1BYJU'S+1.
The hallmark now comprises exactly three elements:
BIS logo
Purity mark (e.g. 22K916, 18K750, etc.)
Six‑character alphanumeric HUID code (e.g. “A1B2C3”) ThePrint+2BIS Services.
This change was introduced to eliminate ambiguity and provide each individual item with its own traceable identity.
July 1, 2021: HUID hallmark introduced; all new items hallmarked from this date forward receive unique HUID codes.
April 1, 2023: Sale of any gold jewellery or artefacts without a valid six‑digit HUID became prohibited. That means from this date only HUID‑based hallmarking is legally allowed in India. Old four‑mark items existing in inventories could be sold only until March 31, 2023—but no new four‑mark items could enter the market after that BYJU'SVikaspediaHindustan Times.
Since then, every piece put on the market must carry a laser‑etched HUID, the BIS logo, and the purity code.
4. Why HUID Was Needed: Key Drivers
a. Traceability & Anti‑Fraud Measures
Every piece of jewellery can now be uniquely identified via its HUID, making it easier to trace back to the jeweller and hallmarking centre, reducing fraud or misrepresentation ThePrint+6Audra Jewel Industry+6Surepass+6BIS Services+3jjjewellersbhalla.com+3BYJU'S+3.
b. Consumer Confidence & Protection
Consumers gain confidence knowing that each piece is individually certified and can be verified using the BIS CARE app. If HUID verification fails, it raises immediate concern Reddit+12jjjewellersbhalla.com+12ThePrint+12.
c. Simplification & Standardization
Automating hallmark issuance through a system‑generated code removes jeweller/assayer discretion, reduces human error or manipulation, and ensures consistency BIS ServicesSurepass.
d. Market Integrity & Legal Mandate
By prohibiting non‑HUID jewellery sales from April 2023, the government strengthened regulatory compliance and consumer trust Prabhat Times+9Vikaspedia+9Hindustan Times+9.

6. HUID in Practice: How to Recognize & Verify
a. Spotting the HUID
Locate the hallmark using good lighting or magnification.
You should see the three marks side by side: BIS logo, purity code, and the six‑character HUID.
b. Using the BIS CARE App
Download the BIS CARE app (Android/iOS).
Navigate to “Verify HUID” feature.
Enter the code; the system returns hallmarked information:
Jeweller name & registration number
Hallmarking centre name
Date of hallmarking
Purity & fineness grade
Mismatch or non‑recognition indicates non‑compliance or potential fraud Vikaspedia+9CNBC TV18+9crackittoday.com+9BYJU'S+3Surepass+3BIS Services+3.
7. Real‑World Scenarios & Consumer Issues
Example from Consumer Reports
A user on Reddit reported buying gold earrings at an exhibition in Bengaluru in 2024 for ₹4 lakhs each—but they lacked HUID. The seller offered delayed sealing, which raised suspicion. Other jewellers and consumers confirmed that jewellery without HUID holds no resale value and is not legally verified. Many advised the buyer to file consumer complaints. Selling non‑HUID jewellery post‑March 2023 is illegal and risky Reddit+1Vikaspedia+1.
8. Statistical Growth & Scale
Over 1300 BIS-recognized Assaying & Hallmarking Centres (AHCs) are now functional.
Over 140,000 jewellers have registered with BIS CNBC TV18+4BIS Services+4BYJU'S+4.
In the voluntary hallmark era, highest recorded was 4.49 crore pieces in 2018–19.
Since mandatory rollout and with HUID in place, over 14 crore gold articles have been hallmarked with HUID from July 1, 2021 to present day BIS Services+1BYJU'S+1.
Currently, 300,000+ gold articles are hallmarked every day with HUID codes BYJU'SCNBC TV18.
9. Limitations, Challenges & User Concerns
a. Stock of Old (Non‑HUID) Jewellery
Some jewellers had leftover inventory marked under the old four‑marks regime. While sale of that inventory was allowed until March 31, 2023, consumers still occasionally encounter old articles without HUID.
b. Visibility of HUID
Tiny size and placement of etching make it hard to read without magnification. Shoppers should insist on clarity before buying.
c. Counterfeit or Duplicate HUID
Although the system is designed to prevent duplication, rogue actors might use forged HUID codes or fake certificates. Always verify via BIS CARE app to avoid scams
d. Digital Access Issues
Some consumers lack access to smartphone apps or internet, which limits their ability to verify codes. Retailers should assist users in checking on the spot or provide printed verification.
10. How to Best Utilize HUID as a Consumer
Always insist your jewellery has all three marks: BIS logo, purity, and HUID.
Verify the code instantly using the BIS CARE app—or request printed verification.
Avoid exhibition sellers or unregistered jewellers unable to show HUID verification.
If doubt arises, request purity testing independently or ask for legal remedies.
Know your rights: selling gold without HUID post‑April 1, 2023 is legally prohibited. Consumers can lodge complaints with consumer courts or authorities.
11. Impact Across the Industry
Jewellery Retail Chains
Major jewellery chains like Malabar Gold & Diamonds adopted HUID compliance immediately, withdrawing all non‑HUID stock after April 1, 2023. Their spokesperson described HUID as transformational, providing transparency, traceability, and strengthening consumers’ trust in gold purchases BIS Servicesjjjewellersbhalla.comRedditThePrint.
Regulatory & Consumer Affairs Bodies
HUID marking enables centralized data collection on hallmark activity, jeweller registration, and product traceability. This improves monitoring, regulatory oversight and support for consumer grievances ThePrintPrabhat Times.
12. Takeaways
Starting April 1, 2023, only jewellery with a valid HUID (plus BIS logo and purity mark) can legally be sold. Old four‑mark stock could not enter the market after that date.
Consumers can verify the HUID online or via the BIS CARE app to confirm purity, jeweller details, hallmarking centre, and date.
HUID offers significant benefits: tamper‑protected traceability, fraud reduction, enhanced transparency, improved resale value, and legal protection.
