US ZIP Code Map adds free ZIP code radius search

US ZIP Code Map has launched a free tool that finds ZIP codes within 1 to 50 miles of any U.S. ZIP code or place and plots the results on a map. The feature is designed to help businesses, marketers and researchers build local service areas faster without searching ZIP codes one by one.

Why it matters: - The new radius search turns a distance question into an actionable ZIP code list for local planning. - Businesses can use the tool to define service areas, target advertising and evaluate delivery zones. - Marketers and researchers can quickly identify nearby communities without manual ZIP code lookups.

What happened: - US ZIP Code Map added a free radius search for nearby ZIP codes. - Users can enter a ZIP code or place, choose a radius from 1 to 50 miles, and view nearby ZIP codes on an interactive map. - The results also appear in a list below the map for easier review and research. - The tool is available at the radius search tool.

The details: - The radius search is part of US ZIP Code Map, a free website for exploring ZIP codes and surrounding areas. - The site also includes ZIP code pages with Census data such as population, median household income and median home value. - ZIP codes can also be explored by state, city and county. - The site includes national and state rankings for several demographic measures. - The radius tool uses straight-line distance, not driving distance. - ZIP codes are included based on the distance between Census ZIP Code Tabulation Area internal points and the selected starting location. - The site notes that USPS ZIP codes are for mail delivery, while the Census Bureau's ZIP Code Tabulation Areas, or ZCTAs, are used for mapping and statistics. - US ZIP Code Map says its methodology section explains how its maps and geographic calculations are created. - The radius search is free and does not require an account or registration.

Between the lines: - The launch reflects a broader need for practical local-market tools that connect geography with ZIP code lists. - Using ZCTAs instead of postal delivery boundaries keeps the mapping approach aligned with Census geography. - A company spokesperson said, "A lot of businesses think about their market in miles from a location, but then need an actual list of ZIP codes to work with. We wanted to make that step simple."

What's next: - The radius search joins the site's existing ZIP code maps, demographic data, nearby ZIP code information, city and county pages, and ZIP code rankings. - Visitors can also explore ZIP codes, cities, counties and states at US ZIP Code Map. - More information about the site's data sources and mapping methodology is available at the methodology page.

The bottom line: - US ZIP Code Map is trying to make local ZIP code research faster by pairing an interactive map with a free radius-based search tool.
