Is my county in a flood zone?
FEMA scores flood hazard county by county, and separately tracks how many homes required to carry flood insurance actually do. This shows you both, for all 3,144 US counties, straight from the National Risk Index. Free, no email.
Read this before you rely on it
These are county figures. FEMA's actual flood zone map, the A, AE, V, VE and X letters a lender asks about, is a parcel-by-parcel service, and no honest site publishes it in bulk. If you need the answer for one address, every county page here links straight to FEMA's own Flood Map Service Center, which is free and authoritative.
What this site is good for is the question before that one: how much flood hazard does this county carry, and how many of the people already required to insure actually do.

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. FloodZoneFinder 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.
