FloodZoneCheck

The question this site answers

"Am I in a flood zone" doesn't have one national answer — FEMA scores flood hazard county by county, and separately tracks how many homes required to carry flood insurance actually do. FloodZoneCheck reports both, for 3144 US counties covering 51 states and roughly 340,110,988 people, straight from FEMA's National Risk Index and NFIP policy data — no averages standing in for a real number.

County data, not a parcel guess

FEMA's actual flood zone map (A, AE, V, VE, X) is a live, parcel-by-parcel lookup service, not something publishable in bulk — so this site is honest about working at county grain, and links every page to FEMA's own Flood Map Service Center for the one-address answer a lender or insurer will actually use.
