BIS Care App: How to Check ISI Mark on Heaters and Geysers

The BIS Care app is the official way to check whether an ISI marked product is genuine, and winter is a good time to use it. Room heaters, geysers and chargers all run hot or draw heavy current, so a fake mark is a real risk. This guide shows how to verify a licence number and how to file a complaint.

What the BIS Care app does

According to the Bureau of Indian Standards, the app gives consumers mobile access to its complaint system and several verification tools. It launched on 27 July 2020 and is free on the Google Play Store. You can use it in Hindi or English.

It is useful because many products carry marks that look official. However, a printed logo alone proves nothing. The app lets you check the number behind the logo.

How to verify an ISI mark with the BIS Care app

An ISI marked product should show a licence number, written as CM/L followed by digits. Here is the check, step by step.

1. Install the BIS Care app from the Google Play Store.
2. Open Verify Licence Details.
3. Type the CM/L number from the product label.
4. Tap Go.
5. Read the licensee details and confirm that the manufacturer matches the brand on the box.

If the number is not found, or the name is different from the maker, treat the product with caution. Ask the seller for an explanation before you pay.

How to check a CRS registration number

Some electronics, such as certain chargers and adapters, carry a registration mark instead of an ISI mark. For these, open Verify R-No under CRS and enter the eight digit R number. The app then shows whether the product matches the relevant Indian Standard and whether the manufacturer is registered.

You can also scan the QR code on a BIS issued licence document to verify the licence or registration number.

Why this matters for winter appliances

Heaters and geysers heat water or air for hours, and poorly made ones can overheat. A genuine licence does not remove every risk, but it shows the maker has met a safety standard. So it is worth the thirty seconds before you buy.

Also use safe habits at home. Plug heavy appliances into proper sockets and avoid overloaded extension boards. Our guide on charging and plug safety covers the basics.

How to file a complaint in the app

If you find a fake mark or a poor quality product, you can complain inside the app. Register with your name and mobile number, then verify with the OTP. Email is optional.

1. Choose a complaint type, such as misuse of the ISI Mark, misuse of the CRS Registration Mark, product quality or misleading advertisements.
2. Describe the issue, preferably with supporting evidence such as photos of the label.
3. Submit the complaint.
4. Track the status later from your complaint history.

Other useful features

The app also lists products under compulsory certification and registered manufacturers. You can search a standard by its IS number and find BIS recognised laboratories. So it works as a small reference guide too.

When you replace old appliances, remember to dispose of the old ones properly. Our explainer on how to dispose of old electronics shows the rules.
