PartsPerk is independent. Manufacturer names, NSN codes, CAGE codes, and part numbers identify sourcing context only — never affiliation, authorization, fit, airworthiness, or live inventory.
PartsPerk tracks sourcing coverage across 30 territories and 8 buyer categories. 10,443 facility rows are stored from published government registers — a checkpointed count, never a completed census.
