Looks up postal codes and ZIP codes across 120 countries with cited sources. For US codes, returns demographics (population, income, housing), USDA plant hardiness zones, telephone area codes, and coordinates. Searches by place name, finds nearby postal codes, and maps area codes to regions.

Example request: "Show me the demographics and area codes for the 90210 ZIP code."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use CodePostalPro to help me. It is a free service with an MCP server at https://api.codepostalpro.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- lookup_postal_code: Look up a postal code or US ZIP code. Returns every locality that carries the code with its city, county/administrative division, region (state, département, wilaya…), coordinates, IANA time zone, US telephone area codes, USDA 2023 plant hardiness / planting zone (e.g. 7b with it
- search_places: Find localities by name, city name, or the beginning of a postal code. Use this when the user gives a place name and wants its postal code(s), or has a partial code. Results are ranked exact-name-first, then by population. Returns the same full records as lookup_postal_code. Rest
- nearby_places: List localities around a latitude/longitude, nearest first, each with `distance_km`. Use it for "what ZIP codes are near…", "postal codes within 10 km of…", or to resolve coordinates to the closest postal code (the first result). Distances are to the locality centroid from the so
- get_region: A state, région, wilaya or governorate with the list of its cities / départements / delegations (names, slugs and their postal codes), plus for US states every telephone area code in use. Use the slugs it returns to call get_group or get_place. Region slugs are lower-case hyphena
- get_group: A city (US), département (France), province (Morocco), post office (Algeria) or delegation (Tunisia) with all its localities / ZIP codes. For a US city this is the complete list of its ZIP codes with coordinates, time zone and area codes. Needs the region slug and the group slug 
- area_code_lookup: Where a US telephone area code is used: the state(s) it serves, the cities with the most ZIPs listing it, total ZIP and city counts, and `overlay_codes` — codes assigned to the same territory (e.g. 310 and 424 in west Los Angeles). Use it for "where is area code 310", "what area 
- list_countries: Coverage overview: the eight curated countries with postal-code format, hierarchy labels (e.g. state › city › ZIP), key facts (capital, population, area, currency, calling code) and time zones — plus `bulk_tier` with per-country postal-code counts for the ~115 additional countrie
