Step-by-Step: How to Verify on the BIS Care App

Step 1: Download the BIS Care app from Google Play Store or Apple App Store. It's free and official.

Step 2: Open the app and go to 'License Search'.

Step 3: Search for the brand name (e.g., 'HYV') or the IS number (IS 17526:2021) for water bottles.

Step 4: The app will show all certified products from that brand with their license numbers, product types, and certification status.

Step 5: Cross-reference the certification number on the bottle's label with the app listing.

The ISI Mark — What to Look For

The ISI mark is a circular logo with 'ISI' inside and the IS number (IS 17526:2021 for water bottles) printed next to it. Certified bottles must display this mark on the product or packaging. The presence of the mark alone is not sufficient verification — always cross-check on the BIS Care app, as some uncertified products counterfeit the mark.

💡 Red Flags for Fake Certification

If a brand claims BIS certification but (1) the product is not findable on the BIS Care app, (2) the IS number on the label does not match IS 17526:2021, or (3) the certification number doesn't match the app listing — treat the certification claim as unverified. Report suspected counterfeit marks to BIS at bis-mcp@gov.in.
