U.S. zip code update

Touchstone’s U.S. zip code data updates for release 2025 (13.0).

Scope

We updated Touchstone’s U.S. zip code data to align with the Florida Commission.

Touchstone-specific updates

Key improvements include:

  • Updated zip code boundaries using population-weighted centroids.
  • County and state assignment changes and backfill updates for affected zip codes.
  • Retired and unsupported zip codes are remapped to supported zip codes.
  • New zip codes are added with full county and state mappings.
  • City and related tables updated to reflect zip code changes.
  • CLF/CLA exports have been updated with appropriate data mappings for downstream use in Touchstone Re.
Important: After upgrade, you must re-geocode U.S. exposure to utilize the updated U.S. boundaries data.

Verisk has also updated disaggregation data to incorporate both the latest zip code changes and enhancements to the U.S. Industry Exposure Database. These updates apply to all models covering the United States.
