States & Provinces
Every Weights & Measures office in the United States, plus Canada’s federal authority and its 232 authorized service providers — verified from official government sources.
The office shown is the Weights & Measures division that actually schedules device inspections and placed-in-service checks — often a small unit inside the state Department of Agriculture. Call early: in many states, getting an inspector out takes weeks. Pins mark each program's published office address (ZIP-code precision); New York and Pennsylvania publish no street address and are pinned at their agency's home city.
All 51 jurisdictions
Every state plus the District of Columbia — requirements, the responsible agency, and the official registry of licensed service companies where one is published.
Canada — 232 authorized service providers
Canada does not work like the United States. There is no province-by-province weights & measures office: Mesures Canada / Measurement Canada is the single federal authority, and it authorizes private companies to inspect and certify devices. Browse those providers by province below, or verify any of them on Measurement Canada’s official site.
