BIS hallmark verification takes less than a minute: open the BIS CARE app, enter the six-character HUID number engraved on your jewellery, and confirm the purity, jeweller name, and hallmarking centre it returns match what you were told at the counter. This single check is the clearest way to know whether the gold you're buying in Bengaluru is genuinely as pure as claimed, and it works whether you're at a large chain store on MG Road or a smaller neighbourhood jeweller in Jayanagar or Kalyan Nagar.
What BIS Hallmark Verification Actually Checks
BIS hallmark verification confirms that a piece of gold jewellery has been independently tested and certified by a Bureau of Indian Standards-licensed Assaying and Hallmarking Centre, rather than simply trusting a jeweller's own purity claim. Hallmarking gold jewellery has been mandatory in India since June 2021, and every hallmarked piece must carry three specific marks: the BIS triangular logo, the purity expressed as a fineness number, and a unique HUID (Hallmark Unique Identification) code specific to that individual item. The HUID is what makes real verification possible it's tied to a central BIS database recording exactly which centre tested the piece, on what date, and at what confirmed purity.
How to Verify BIS Hallmark and HUID Step by Step
Locate the hallmark on your jewellery, usually laser-etched in a discreet spot inside a ring band, on the clasp of a necklace, or the back of a pendant.
Note down the six-character HUID code alongside the purity marking.
Download the BIS CARE app (available for Android and iOS) or visit the BIS website's verification page.
Enter the HUID code in the verification section.
Confirm the results show the correct purity, the jeweller's registered name, and the assaying centre and that the code returns a valid result at all, since a code that doesn't exist in the database means the hallmark itself is fake.
Understanding Purity Codes: 585, 750, 916, 999
The fineness number on a hallmark tells you the actual gold content, and it's worth knowing these independent of what a jeweller tells you verbally:
585 corresponds to 14 karat gold (58.5% pure)
750 corresponds to 18 karat gold (75% pure)
916 corresponds to 22 karat gold (91.6% pure)
999 corresponds to 24 karat gold (99.9% pure)
If a jeweller tells you a piece is 22 karat but the hallmark reads 750, you're being sold 18 karat gold at a higher purity's price a mismatch worth catching before you pay, not after.
Is Silver Hallmarking Mandatory in Bengaluru Too?
Gold hallmarking rules are well established, but silver hallmarking regulation has been shifting and reporting on its current status is inconsistent even among informed sources. Some recent guidance indicates silver hallmarking has moved toward mandatory status, while other sources describe it as still voluntary as of 2026. Given this genuine uncertainty, it's worth asking your jeweller directly whether a silver piece has been hallmarked and checking the BIS website for the latest confirmed position rather than relying on assumptions either way.
What to Do If a Jeweller's Hallmark Doesn't Verify
If the HUID doesn't return a result, or the details don't match what you were told, don't complete the purchase. If you've already bought the piece, you have grounds for a complaint with BIS directly, since selling unhallmarked or falsely hallmarked gold jewellery in mandatory districts is illegal and carries penalties for the seller, including fines that can run up to several times the cost of the article. Keep your invoice and any packaging showing the claimed purity, since these support a formal complaint if verification fails after purchase.
Practical Tips for Buying Gold Jewellery in Bengaluru
Always verify the HUID before finalising a purchase, not just at home afterward
Ask for the complete invoice showing purity, weight, and making charges as separate line items
Compare making charges across a couple of jewellers, since these vary significantly and aren't standardised
For high-value purchases above ₹2 lakh, be prepared to provide PAN or Aadhaar details, as required under current regulations
Established chains like Joyalukkas on MG Road, Malabar Gold and Diamonds in Jayanagar, and Jos Alukkas in Kalyan Nagar are BIS-registered outlets, but verifying the HUID yourself takes the same minute regardless of how established the jeweller is
Red Flags When Buying Gold Jewellery
No hallmark at all on a piece being sold in a district where hallmarking is mandatory this is illegal, not just a quality concern
A HUID that doesn't verify on the BIS CARE app or website
Reluctance to let you check the hallmark before completing a purchase
Verbal purity claims that don't match the fineness number actually stamped on the piece
Unusually low making charges paired with unusually high urgency to close the sale quickly
You can browse jewellers listed on BengaluruConnect across the city, and use the HUID verification step above at any of them before completing a purchase.
A BIS hallmark verification check costs nothing and takes under a minute, which makes it one of the simplest, highest-value habits a gold buyer in Bengaluru can build regardless of how much you trust the jeweller you're standing in front of.
