How to Check a Gold Jewellery HUID Using the BIS Care App
A HUID can be checked using the official BIS Care application.
The process is:
- Locate the HUID on the jewellery
- Open the BIS Care app
- Select Verify HUID
- Enter the HUID exactly
- Compare the displayed information with the article and invoice
BIS states that its application allows consumers to verify hallmarked jewellery using the HUID feature.
What is a hallmark?
Hallmarking is the official recording of the proportionate precious-metal content in an article.
BIS says that the purpose of hallmarking includes protecting consumers against adulteration and supporting legal standards of fineness. India’s BIS hallmarking framework covers gold and silver precious-metal articles.
A BIS hallmark on gold jewellery includes:
- BIS Standard Mark
- Purity in carat and fineness
- Six-character HUID
The jeweller or manufacturer may also place a separate identification mark.
What does 22K916 mean?
The expression has two connected parts:
- 22K refers to 22-carat gold
- 916 refers to 916 parts of gold per 1,000 parts of the alloy
Other examples include:
18K75014K585
The marking should be read as a declaration of purity, not as the item’s weight or price.
What is a HUID?
HUID means Hallmark Unique Identification.
It is a six-character alphanumeric identification attached to a hallmarked gold article under the BIS system.
A HUID helps a consumer access information connected with the hallmarked article, including the jeweller’s registration information through the BIS Care app.
How to locate the hallmark
The marking may be small and may appear on:
- Inner surface of a ring
- Clasp of a chain
- Back of a pendant
- Inner surface of a bangle
- Suitable area on an earring
- Individual detachable component
BIS states that each article in a pair and each detachable part should carry the appropriate hallmark. Jewellers are also required to provide magnification facilities for customers to inspect the mark.
Ask the jewellery specialist to show you:
- BIS mark
- Purity/fineness mark
- HUID
How to verify a HUID step by step
Step 1: Download the official BIS Care app
BIS provides the application for Android and iOS.
Step 2: Register in the app
Follow the mobile-number registration process requested by the application.
Step 3: Choose “Verify HUID”
Do not use an unrelated licence or product-verification option.
Step 4: Enter the exact HUID
Pay attention to letters and numbers. Small engravings can be difficult to read without magnification.
Step 5: Review the displayed information
Compare the app result with:
- Jewellery in your hand
- Purity represented by the seller
- Jeweller details
- Invoice description
Ask for clarification before completing the purchase when the information does not correspond.
What should appear on the invoice?
BIS says that the invoice for hallmarked precious-metal articles should include:
- Description of each article
- Net weight of the precious metal
- Purity in carat and fineness
- Hallmarking charges
BIS also advises customers to retain an authentic invoice because it is important for complaint and dispute redressal.
Does BIS hallmark certify a diamond?
No. BIS hallmarking relates to the precious-metal content of gold and silver articles.
A diamond may have separate grading or certification documentation, but it should not be described as a “BIS-hallmarked diamond.”
For diamond jewellery, ask separately about:
- Gold purity
- HUID
- Diamond grading information
- Certification provider
- Carat weight
- Cut, colour and clarity
- Return, exchange and service conditions
Can a hallmark be verified after purchase?
Yes. The HUID can be checked through the BIS Care app.
BIS also states that consumers can have jewellery or samples tested at a BIS-recognised Assaying and Hallmarking Centre on a chargeable basis, with an assay report issued for the article tested.
Jewellery shopping in Mundakayam
When purchasing gold jewellery in Mundakayam, ask to see the hallmark, HUID and invoice details before payment.
At Aladis Jewellery, the customer-facing content should use precise wording:
Eligible gold and silver jewellery is hallmarked in accordance with applicable BIS requirements.
Avoid saying that gold, diamonds and silver are all “BIS certified” as though the certification applies identically to every component.
Frequently asked questions
Can two jewellery pieces have the same HUID?
A HUID is intended to identify a hallmarked article. Enter the HUID in the official BIS Care app and compare the result with the piece presented.
Is HUID the same as purity?
No. Purity is shown separately through a carat-and-fineness mark such as 22K916. HUID is the article’s identification.
Should both earrings have hallmarks?
BIS states that each article in a pair should be hallmarked.
Is an invoice still necessary when jewellery has a HUID?
Yes. BIS advises consumers to obtain an authentic invoice for hallmarked articles
