About FludZone

Making FEMA flood zone data accessible to everyone.

Our Mission

FludZone was built to make flood risk information free and instant. We believe every homebuyer deserves quick, free access to FEMA flood zone data without waiting 3-5 business days or paying $20-30 for a certified lookup. If all you need is a quick answer before making an offer, you should not have to pay for it.

What We Do

Instant Results

Get flood zone data in seconds, not days. Enter any US address and know immediately if it's in a FEMA flood zone.

FEMA NFHL Data

We query FEMA's National Flood Hazard Layer directly, the same federal database used by industry professionals.

For Homebuyers

Whether you're buying your first home or investing in property, FludZone gives you the flood risk information you need before making an offer.

Our Data Source

FludZone uses data from the FEMA National Flood Hazard Layer (NFHL), the official digital compilation of effective Flood Insurance Rate Maps (FIRMs) combined with Letters of Map Change. This includes:

Note: The NFHL does not yet cover every community with modernized digital FIRMs. In areas where NFHL data is not available, FEMA may still rely on older paper FIRMs. Always confirm with FEMA resources or a certified determination provider if results are unavailable.

Not a Certified Flood Determination Service

FludZone is an informational tool, not a certified flood zone determination service. We do not issue Standard Flood Hazard Determination Forms (SFHDF), and results from this site cannot be used for mortgage underwriting, insurance issuance, or other purposes requiring a certified determination with Errors & Omissions insurance.

If FEMA has issued a Letter of Map Amendment (LOMA) or Letter of Map Revision (LOMR) for a property, that document is the official, controlling record of its flood zone status, even if this site has not yet reflected it. For real estate transactions, lending, or insurance decisions, always rely on your FEMA determination letter or a licensed flood determination provider rather than this site alone.

How We Keep This Accurate

  • We periodically review our guides and educational content against current FEMA and NFIP documentation to ensure accuracy.
  • When FEMA changes key programs (such as Risk Rating 2.0 updates or map revision procedures), we update our content to reflect those changes.
  • We test our flood zone lookup results against FEMA's own Map Service Center as a routine accuracy check.
  • We do not alter, interpolate, or reinterpret FEMA data. FludZone presents the same NFHL information in a more accessible format.
  • All educational content is fact-checked against the FEMA NFIP Flood Insurance Manual (October 2025) and 44 CFR Part 59.
