## Description

PostalCodeCheck is an online postal-code lookup service that helps people identify the city or locality, region, and coordinates associated with a ZIP code, postcode, or other postal code. Its searchable directory covers 95 countries and lists more than 887,000 codes, with country-specific collections that include U.S. ZIP codes, UK postcodes, German PLZ codes, and Indian PIN codes. Users can search by code to find a place or browse city pages to see the codes used there. The service also provides country directories, postal-code guides, and statistics, and explains how postal systems differ and why a code may cover multiple places. For developers, PostalCodeCheck offers postal-code results in JSON through a free API, with no registration required for the basic service. Users needing higher request limits can obtain a free IPNOVA API key. The site says its data comes from the GeoNames postal dataset, is refreshed monthly, and is provided under the CC BY 4.0 licence. PostalCodeCheck is built in Cyprus by IPNOVA Systems Ltd.
