Postal Code Lookup — ZIP to City & Coordinates

Turn postal and ZIP codes into locations in bulk with the Postal Code Lookup. Paste a list of codes, pick a country (or prefix each code with its own), and export the city/place name, state or region, and latitude/longitude for each — one clean row per code as JSON, CSV or Excel.

Built for address forms and validation, shipping and logistics, geo enrichment, store locators and analytics, it covers many countries and resolves codes to real places with coordinates.

What it does

• 📮 ZIP/postal → place — city or place name and state/region for each code.
• 📍 Coordinates — latitude and longitude for mapping and distance calculations.
• 🌍 Many countries — US, GB, DE, CA, FR, AU and more; set a default or prefix per code.
• 🔀 Multiple places — codes that map to several places return them all.
• ⚡ Bulk — look up long lists of codes in one run.
• 📤 Export anywhere — JSON, CSV or Excel, or straight into a form, CRM or map.
