erifying a BIS Certificate online is simple when you have the correct details. Start by collecting the relevant identification number—either the CM/L number for products certified under the ISI Scheme or the Registration Number (R-number) for products covered under the Compulsory Registration Scheme (CRS). You should also have the product brand name and the exact model or variant information for accurate verification.

Visit the BIS/Manak online portal and select the option to Check License or Check Registration. Enter the CM/L number or R-number in the search field. If required, you can refine the search by applying filters such as the brand name or the applicable Indian Standard (IS).

A valid BIS record will display essential details, including the licensee or manufacturer name, brand, model or catalogue reference, applicable IS number, and the current certification status (active, suspended, or expired). Carefully compare this information with what is printed on the product, packaging, or label. For electronics and IT products under CRS, the R-number is usually mentioned on the label or packaging, while ISI-certified products must display the ISI mark along with the CM/L number.

If the record does not appear, double-check the entered details for spelling errors or variations in model numbers, such as hyphens or spaces. If verification still fails, request a copy of the official BIS license or registration certificate from the manufacturer or seller. A BIS mark alone is not valid proof unless the product details are visible in the BIS database.

For tenders, audits, or regulatory inspections, it is recommended to download or print the online verification result and retain it in your quality or compliance records. Re-verification should also be carried out when new variants are introduced or when product components change, to ensure the BIS approval continues to cover the supplied configuration.
