Zip-Codes.com Location Intelligence: Spatial Analysis, Districts & 14+ Years of Demographics

ClaudeCommunityby Zip-Codes.com

Validate a US address and see the place behind it in the same call. Zip-Codes.com answers from current USPS data, updated monthly, and Census boundaries, so Claude looks addresses and ZIP Codes up instead of guessing them. A messy one-line address comes back standardized with its ZIP+4, and you can add location intelligence on top: 14 years of normalized American Community Survey data (2011–2024) across Census geographies, mapped congressional and state legislative districts, and school districts. Survey figures describe areas, not individuals, and carry margins of error. ZIP boundaries follow USPS carrier routes and are refreshed quarterly, and PO Box and single-organization ZIP Codes are included. Boundary enrichments show how much of a ZIP's area falls in each county or district, beside the USPS assignment; the two can differ. Look up US ZIP Codes, ZIP+4s, Canadian FSAs and postal codes, or the code containing a latitude/longitude pair. Find postal areas within a radius, measure straight-line distance, or resolve a misspelled place name first. Census TIGER/Line boundaries cover 2010–2025, and ACS field names stay the same across releases, so a place can be compared year over year. Address validation and survey estimates are US only. The 11 tools are read-only. Free reference tools cover ZIP statistics, data sources and citations, USPS city-name rules, counties and metropolitan areas. This connector needs no sign-in and runs in demo mode: real values, with some deeper fields withheld and long lists shortened. Demo codes and addresses, such as ZIP 90210 and the Empire State Building, return full depth.
