Steps

  1. Navigate to the ASME Certificate Holder Search at caconnect.asme.org/directory
  2. Search by company name, location, or certificate type to find certificate number, scope, authorization date, and expiration date
  3. Cross-reference the scope of the certificate (e.g., U for pressure vessels, S for power boilers, PP for pressure piping) against the actual product being procured, since a company can hold one stamp type without holding others
  4. Confirm the certificate has not expired by checking the listed expiration date, not just its presence in the directory
  5. If the company cannot be found, try partial-name search terms since legal entity names on file may differ from trade names used publicly
