Verify Gold Purity with BIS Care App

Gold has always held immense cultural, emotional, and financial value in India. From weddings and festivals to long-term investments, gold jewellery is deeply woven into everyday life. However, issues such as under-karating, fake hallmarking, and misleading purity claims have historically affected consumers.

To safeguard buyers and promote transparency, the Government of India made hallmarking mandatory for gold jewellery and introduced a digital verification system through the BIS CARE App. This official app allows consumers to instantly verify gold purity, check product authenticity, and raise complaints, all from their smartphone.

Developed by the Bureau of Indian Standards (BIS), the BIS CARE App is a powerful tool every gold buyer in India should know about.

What Is Gold Hallmarking and Why Is It Important?

Hallmarking is an official certification process that verifies the purity (fineness) of precious metals like gold and silver.

In India, hallmarking is regulated by BIS to:

Prevent adulteration
Ensure fair pricing
Protect consumers from fraud
Maintain uniform quality standards

Components of a BIS Gold Hallmark

Every hallmarked gold jewellery item must have:

BIS logo: confirms BIS certification
Purity mark: such as 22K916, 18K750
HUID (Hallmark Unique Identification): a unique code for digital verification

Understanding HUID (Hallmark Unique Identification)

The HUID is the backbone of digital hallmark verification.

Key facts about HUID:

A 6-character alphanumeric code
Unique to each jewellery item
Engraved or laser-marked on the jewellery
Generated at a BIS-recognised Assaying & Hallmarking Centre (AHC)

Even two identical rings will have different HUID numbers. Without HUID, jewellery cannot be digitally verified and is considered non-compliant.

What If the BIS Hallmark Verification Details Don’t Match?

If the BIS CARE App displays information that does not match the claims made by the jeweller, it should be treated as a serious warning sign. Any mismatch indicates that the jewellery may not be properly hallmarked or may not comply with BIS regulations.

Situations Where You Should Be Cautious

You should be alert if the app shows any of the following:

“No record found” after entering the HUID, which may indicate a fake or invalid hallmark
Wrong purity (for example, the jeweller claims 22K but the app shows 18K)
Incorrect jeweller details, such as a different registration number or name
Incorrect Assaying & Hallmarking Centre (AHC) details, suggesting improper or unauthorised hallmarking

These discrepancies mean the jewellery cannot be reliably verified through BIS records.

What You Should Do in Such Cases

1. Avoid Purchasing the Jewellery

If verification is done before purchase, do not proceed until the jeweller provides a clear and valid explanation. Purchasing unverified jewellery can lead to financial loss.

2. Collect and Preserve Evidence

Take clear photographs of:

The jewellery item and HUID engraving
The bill or invoice issued by the jeweller
The BIS CARE App verification screen shows the mismatch

This evidence is important for further action.

3. Raise a Complaint via the BIS CARE App

Use the Queries & Complaints feature in the app to report the issue.

Select the relevant complaint category
Upload photos and supporting documents
Submit the complaint for review

After submission, you will receive a complaint reference number, which can be used to track the status of your case.
