Confirm an ASME Boiler and Pressure Vessel Code (BPVC) certificate holder's status using ASME's public directory, understanding that the BPVC text itself is paywalled.

Steps
Use ASME's Certificate Holder Search (caconnect.asme.org/directory or asme.org's "Locate ASME Certified Companies") to confirm a manufacturer's ASME Certification Mark status, certificate number, scope, and expiration.
Note ASME's public count of over 6,800 active Certificate Holders in the BPVC program — treat an absent listing for a company claiming an ASME stamp as a red flag worth following up on.
Do not attempt to source the full BPVC text for free — it is sold as a paid publication in multiple sections (I, VIII, IX, etc.), individually or as a set, with no free-to-read equivalent.
For code interpretation short of purchase, rely only on ASME's own published interpretations/errata, not third-party summaries, for anything safety-critical.
If your shop needs its own ASME stamp, note that obtaining one requires a separate accreditation/audit process distinct from this public search tool.
Known gotchas
The Certificate Holder Search confirms a company's authorization to use an ASME stamp; it does not certify any specific vessel — also check the vessel's data report/National Board registration.
ASME BPVC is sold as multiple separate sections — make sure a vendor claiming "ASME BPVC compliant" specifies which section (e.g., Section VIII vs. IX) actually applies to your job.
