The ISO conducts detailed on-site assessments of municipal fire-protection capabilities and collects information for more than 46,000 fire protection areas across the United States. ISO’s audit teams analyze the relevant data and assign a PPC rating from 1 to 10. Class 1 represents exemplary public protection, and Class 10 indicates that the area’s fire-suppression program doesn’t meet the minimum criteria. Most, but not all U.S. insurance companies use this rating to assign the annual homeowner and commercial insurance premiums charged to residents and businesses within a given fire protection district.

Split classifications: When you see a split classification for a community — for example 5/9 — the first number is the class that applies to properties within 5 road miles of the responding fire station and the second number is the class that applies to properties that are not within 5 road miles of a fire station.
