Dear Vipul, pl.see the following few of ISO certification bodies, which are accrediated.

1)DNV GL Business Assurance India Pvt. Ltd.

2)Tuv India Pvt. Ltd.

3)Bureau Veritas (India) Pvt. Ltd.

4)Integrated Quality Certification Pvt. Ltd., etc.

Dear Sir. Concerning your issue about the certified Body that provides ISO certification and Valid. When choosing a certification body, you should:

• Evaluate several certification bodies.
• Check if the certification body uses the relevant CASCO standard
• Check if it is accredited. Accreditation is not compulsory, and non-accreditation does not necessarily mean it is not reputable, but it does provide independent confirmation of competence. To find an accredited certification body, contact the national accreditation body in your country or visit the International Accreditation Forum. I think the following below links may help you in your analysis:

ISO maintains a list of accrediting bodies. www.iso.org. It is readily found with a very basic Internet search that would have taken less time than it took you to post this question.
