Address and service requests
The address you enter is sent to the U.S. Census Geocoder. The selected coordinates are sent to FEMA’s map service. Map tiles are requested from OpenStreetMap and receive your IP address and the viewed tile location. Each provider’s own privacy terms apply. The site does not sell address searches.
Local cache and security records
Address matches are served from cache for up to 30 days, map results for 24 hours. Expired files are removed during scheduled cache pruning. Rate limiting stores a hash of the connection IP and short-window request counts. Hosting access logs may contain URLs, IP addresses and timestamps; an address in a GET URL can therefore appear in browser history or server logs. Avoid submitting sensitive personal information.
Optional cookies
Ads and analytics are disabled by default. Cookie settings saves your optional-service preference in local storage and a first-party cookie for up to one year. Essential lookup, security limits and the readable result work without accepting optional cookies.
