BIS Verification Guide

To check a BIS (Bureau of Indian Standards) CML (Conformity Mark License) number online, check the license status using the official BIS Care App or the Manak Online Portal. You can simply enter the 7- or 10-digit number to see the manufacturer's details and validity immediately. BIS has introduced a standard 10-digit format for CML numbers. For example, if the license number previously was 1234567, the CML number will be 0001234567. With this 10-digit identification code, consumers can easily confirm the authenticity of the CML number.

 

The BIS online facility offers many services to manufacturers, applicants and users. Users can stay updated with compliance conditions, follow the application process, correct any shortcomings, apply for certification, check the CML no.s, make complaints, and renew the certification. These online services enable organisations to comply with regulatory requirements. The application of such digital services allows companies to manage their certification processes efficiently and ensure compliance with requirements.

 

What Is a CML Number?

A CML number (Certification Marks License Number) is a unique 7- or 10-digit identifier issued by the Bureau of Indian Standards (BIS) to manufacturers who have obtained a valid ISI Certification (Scheme-1). This unique identification number ensures that the manufacturer has obtained BIS recognition to use the Standard Mark (ISI mark) on products within the scope of the certification.

 

The CML number signifies that the product complies with the relevant Indian Standard (IS) and that the manufacturing unit has completed the entire BIS certification process, including factory inspections, product tests, and control assessments.

The CML Number can be verified on various official BIS platforms to confirm whether the product's BIS license is valid and active.

  • Use this method when online resources are not enough to verify your CML Number or resolve your licensing issues.

 

What Information You'll See After CML Number Verification

After you verify a CML number, the information regarding the certified product and its manufacturer is displayed by the verification system of BIS, which includes:

  • CML Number
  • Name of the Manufacturer
  • Factory Address
  • Name of the Product
  • Relevant Indian Standard (IS Number)
  • Brand (if applicable)
  • Current Status of the License
  • Validity Period of the License
  • Scope of License (products covered under certification)

 

New 10-Digit CML Number Format

To improve the management and verification of digital licences, the Bureau of Indian Standards (BIS) has decided to standardise all CML (Certification Marks Licence) Numbers to a fixed 10-digit format.

  • The CML Numbers will now all appear in the standardised 10-digit format. 
  • Existing CML Numbers will have an additional leading zero where required to conform to this format. 
  • There will be no change to the validity, coverage, or status of your BIS licence due to this move, as it is just a formatting and administrative change. 
  • Both the old CML Numbers format and the new 10-digit format will be accepted for licence verification and official document purposes during this transitional stage.

How to Identify a Fake or Invalid CML Number?

It is essential to verify the license information for the ISI-marked item before buying or using it on official BIS platforms. Below are some tips for identifying a fake or invalid CML number.

There is no entry against the CML number on the BIS Manak Online Portal or the BIS Care App. The manufacturer's name does not match the information in the BIS verification.

  • The product type does not match the one specified in the BIS licence.
  • The license has expired, been suspended, retired, or is inactive, meaning the manufacturer is no longer allowed to use the ISI mark.
  • The ISI mark or CML number is poorly printed on the packaging, tampered with, misspelt, or in multiple formats.
  • The corresponding IS number is absent or does not relate to the product being sold.
  • The same CML number is used on multiple products and brands, indicating that the BIS licence is misused.

 

Common Mistakes to Avoid While Checking CML Number

To ensure that you are checking accurate and correct information, avoid the following mistakes:

  • Mistyping your CML Number: BIS uses a 10-digit CML Number format and may add leading zeros as needed.
  • In general, during the transition period, you can enter your old or new number, but make sure you enter the numbers correctly. 
  • Confusing CML Number with an R Number or a serial number: CML is provided under the ISI Certification Scheme, while an R Number is issued under the Compulsory Registration Scheme.
  • Relying only on the printed ISI Mark: Even if a product shows the ISI Mark and CML Number, you still need to verify it on the BIS Manak Online Portal or BIS
  • Care App to confirm the license is valid and active.
  • Disregarding license validity status: Always verify the BIS license status and check how long it is valid.
  • An expired, suspended, or cancelled license means that the manufacturer is no longer entitled to use the ISI mark.

 


Conclusion

To verify the authenticity of ISI-certified products, the best option is to check the CML (Certification Marks Licence) number.

Both of these are the best authentic sources confirming the validity and active status of BIS licenses for various products.
