How to verify an ISO certificate in Italy, the UK and the USA
Check an ISO 9001 or ISO 27001 certificate’s scope, issuing body and status using official accreditation resources — before relying on it in procurement.
The short answer
Check the company name, standard, scope, issuing body and certificate status. ISO does not issue certificates. Use the relevant accreditation database, and contact the issuing body if the record is unclear or absent.
Certification and accreditation are different
An independent certification body assesses an organisation’s management system. An accreditation body assesses the competence of that certification body. ISO develops standards but does not perform certification. Accreditation is not universally compulsory; a buyer can nevertheless require it.
Italy: use Accredia’s certification databases
Search the relevant management-system certification database and compare the organisation, standard and scope with the certificate you received. Records are supplied by certification bodies and can change. An absent result is a reason to investigate, not automatic proof that a certificate is false.
UK: check UKAS-accredited certificates with CertCheck
UKAS CertCheck verifies management-system certificates issued under UKAS accreditation, including certificates issued outside the UK. It is not an inventory of every certificate worldwide. Check the accreditation shown on the certificate before selecting a database.
USA: verify the body’s accreditation through ANAB
ANAB’s directory lists accredited management-systems certification bodies. This verifies the body’s accreditation, not by itself your supplier’s individual certificate. Confirm the relevant standard and ask the certification body to confirm the supplier certificate’s status and scope.
A valid certificate still needs the right scope
Match the certified entity and activities to the service you are buying. For a SaaS, ask whether development, hosting and support are covered. Keep the verification record with the procurement decision and request clarification for any mismatch.
KPIs to track, not promised results
Measure the value of certification
- Internal hours
- Track staff time spent on documentation, evidence and audit preparation before and after support.
- Total cost
- Compare consulting, audit fees and internal staff time on the same scope, including maintenance.
- Buyer confidence
- Track vendor assessments passed, tender eligibility and time spent answering customer checks. Certification alone does not guarantee more sales.
