Flood zone by address
FEMA publishes Flood Insurance Rate Maps (FIRMs) that classify every US address into a flood zone (A, AE, AH, VE, X, etc.) with a base flood elevation where applicable.

What zipradar shows
Pages show the flood zone code, what it means in plain English (1% annual chance zone, 0.2% annual chance zone, or outside mapped hazard), and the base flood elevation where assigned.
Refresh cadence
Quarterly LOMA updates. zipradar honors the regulator's publishing cadence; stale data is flagged rather than silently served.
Limitations
For an official flood-zone determination (required by lenders), consult the FEMA Map Service Center directly. zipradar shows informational classifications only.
