Steps
Understand that Verisk/ISO does not offer a public PPC lookup — PPC data is distributed to insurance companies and agents through ISOnet, a subscription product, not to policyholders or the general public
If you're an insurance agent/company, request ISOnet access or call the ISO number listed on isomitigation.com/ppc for assistance
If you're a property owner, contractor, or fire official without ISOnet access, contact your local fire department or insurer directly, since some informally publish their district's PPC
Do not rely on third-party 'PPC lookup by address' sites as authoritative — cross-check any number they return against your insurer or fire department before using it in a proposal or report
Known gotchas
There is no free, authoritative, address-level public PPC database — anything claiming to be one should be treated as unverified
PPC ratings are set at the fire-district level, not per building, so per-property variation is limited to specific ISO-graded factors (e.g., hydrant/station distance) layered on the district base score
