FAQs

Common Questions

Quick answers to the questions our team receives most often.

How long does the certification process take?
Most ISO certifications are completed within 30–45 days from the date of application, subject to document readiness and audit scheduling. Complex multi-site organisations may take 60–90 days.
What documents are needed to apply?
You will need your organisation registration documents, a completed application form, your management system documentation (manual, procedures, records), and the relevant fee payment receipt. Full checklists are available on our portal.
Is my JDN Assessment Certifications certificate valid internationally?
Yes. JDN Assessment Certifications is accredited by NABCB, which is an IAF MLA signatory. This means certificates issued by us are recognised in all 90+ IAF member economies worldwide.
What is the MSME concession scheme?
Under the Government’s MSME promotion policy, micro and small enterprises are eligible for a 50% subsidy on certification fees. Eligibility is confirmed using your Udyam Registration Number (URN).
How do I verify an JDN Assessment Certifications certificate?
You can verify any certificate issued by JDN Assessment Certifications using the certificate number on our online verification portal. The portal is publicly accessible and available 24/7.
Can I apply for multiple standards together?
Yes. We offer integrated audits for organisations wishing to certify against multiple standards simultaneously (e.g. ISO 9001 + ISO 14001 + ISO 45001). This typically reduces audit time and cost significantly.
