How to check a HUID yourself.
A HUID is a six-character code stamped on hallmarked gold, and it belongs to that one item rather than to the shop that sold it. That single fact is what makes it useful to you.
What is stamped on a hallmarked piece
- BIS mark
- The triangular Bureau of Indian Standards logo.
- Purity
- 22K916 for 22 carat, 18K750 for 18 carat. The number is parts of gold per thousand.
- HUID
- A six-character alphanumeric code, unique to that individual item.
How to verify it
- Step 1
- Find the HUID stamped on the piece. On a chain it is usually on the clasp; on a ring, inside the band. It is small — ask for a loupe, every jeweller has one.
- Step 2
- Install the official BIS Care app, published by the Bureau of Indian Standards.
- Step 3
- Enter the HUID. The app returns the item's purity, the jeweller's registration and the hallmarking centre.
- Step 4
- Check that what the app says matches what you were told at the counter.
What to do if something does not match
Ask. A mismatch is not always fraud — data entry errors happen. But a shop that cannot show you a HUID at all, or discourages you from checking, has told you something important about itself.
Every piece at Nakoda Gold is 916 hallmarked with its own HUID, and you are welcome to stand at the counter and check it on your phone before you pay. Bring gold bought anywhere else and we will test its purity free on the machine, with no obligation.
