How to search.
Search by Company Name, Country/Region, State, City or Certificate Type. Start with the company name and country, then filter by Certificate Type to narrow the results to a specific stamp (U, U2, S, PP, H, N and others).
What to check in the result.
Certificate type and number
Scope of the certificate
Authorization date and expiration date
Company contact details
If the company is not listed.
Check the spelling and any alternative company names. A company that does not appear, or whose certificate has expired, does not hold a current ASME certificate for that scope.

Other marks.
The R, NR and NB stamps and Authorized Inspector credentials are managed by the National Board of Boiler and Pressure Vessel Inspectors.
