National Flood Data was started in 2016 with two contracts to build a reliable flood data service for two real estate data companies. Insurance companies began turning to us shortly afterwards and are now our primary customers. Our approach is very simple: we provide a very reliable, accurate and easy-to-use service and our customers tell us what they need next. We are located in Seattle, Washington. When you call us, we answer the phone.
