Flood Risk Checker

Look up your ZIP code's FEMA flood zone and historical NFIP flood-insurance claims, then see whether flood insurance is recommended for your area.

About This Tool
Enter your ZIP code to see its dominant FEMA flood zone, the number of historical National Flood Insurance Program (NFIP) claims paid in the area, and what the zone means for flood insurance.
  • Dominant FEMA flood zone and what it means for insurance
  • Historical NFIP claims paid and average payout for the ZIP
  • Whether flood insurance is typically required or recommended
Based on FEMA flood-zone designations and the NFIP redacted claims dataset published by FEMA OpenFEMA.
Used to look up the FEMA flood zone and NFIP claims history

How This Checker Works

  1. Enter your ZIP code - we look up the dominant FEMA flood zone for your area.
  2. Review your flood zone - zones starting with A or V are high-risk Special Flood Hazard Areas.
  3. See the claims history - historical NFIP claims and average payouts show how often the area has flooded.

FEMA Flood Zones Explained

ZoneMeaningRiskInsurance
A / AE / V / VESpecial Flood Hazard Area (SFHA). 1% annual chance of flooding (100-year floodplain). V and VE zones add wave hazard along coasts.HighTypically required with a federally backed mortgage
B / X500 / shaded XModerate-hazard area. Between the 100-year and 500-year floodplains (0.2% annual chance).ModerateNot required, but recommended
C / X (unshaded)Minimal-hazard area outside the mapped floodplains. Flooding is still possible.MinimalOptional, available at lower-cost preferred rates

Why Flood Zones Matter

FEMA flood zones tell you the modeled flood risk for an area, which drives whether flood insurance is required and how much it costs. Zones beginning with A or V are Special Flood Hazard Areas, where lenders typically require flood insurance on a federally backed mortgage.

Flood damage is not covered by standard homeowners insurance. You need a separate NFIP or private flood policy. About 25% of NFIP flood claims come from outside high-risk zones, so a lower-risk designation reduces the odds but does not remove them.

Data Sources & Methodology

Data Sources

Methodology

We map your ZIP code to its dominant FEMA flood zone and summarize the historical NFIP claims paid in the area. Zones beginning with A or V are classified as high-risk Special Flood Hazard Areas; B, X500, and shaded X are moderate; C and unshaded X are minimal. Claims counts and average payouts come from the redacted NFIP claims dataset.

Last updated: 2026-06
FEMA flood zones are area-level and do not reflect the elevation or drainage of an individual property. A single ZIP can contain multiple zones; we report the dominant one. The only authoritative source for a property-level flood zone is the FEMA Flood Map Service Center.

Frequently Asked Questions

What does my FEMA flood zone mean?

FEMA flood zones describe the modeled flood risk for an area. Zones starting with A or V are Special Flood Hazard Areas with at least a 1% annual chance of flooding (the 100-year floodplain), where flood insurance is typically required on a federally backed mortgage. Zones B, X500, and shaded X are moderate hazard. Zones C and unshaded X are minimal hazard. A single ZIP can span more than one zone, so check your exact address on the FEMA Flood Map Service Center.

Does homeowners insurance cover flooding?

No. Standard homeowners and renters policies exclude flood damage. You need a separate policy through the National Flood Insurance Program (NFIP) or a private flood insurer. Flood insurance is typically required if you have a federally backed mortgage on a home in a high-risk zone (A or V), and it is available and recommended even in moderate and minimal-hazard zones.

I am in a low-risk zone - do I still need flood insurance?

Flooding can happen anywhere it rains. About 25% of NFIP flood claims come from properties outside high-risk zones. A minimal or moderate-hazard rating lowers your odds but does not remove them, and policies in lower-risk zones are usually cheaper. Many homeowners in B, X500, and X zones still choose to carry a policy.

Where does this flood data come from?

Flood-zone designations come from FEMA's flood maps, and the claims figures come from the redacted NFIP claims dataset published through FEMA OpenFEMA. These are area-level summaries. The authoritative source for a property-level flood zone is the FEMA Flood Map Service Center, and an elevation certificate gives the most precise picture for an individual building.

What should I do if my ZIP is in a high-risk flood zone?

Look up your exact address on the FEMA Flood Map Service Center to confirm the property-level zone, then get a flood insurance quote through FloodSmart.gov or a private insurer. If you have a federally backed mortgage, flood insurance is typically required. You can also reduce risk with measures such as elevating utilities, installing flood vents, and grading the land away from the foundation.
