Frequently Asked Questions

What is better than the GeoNames API?

The GeoNames API is useful for basic search and query functions but relies on crowdsourced project data with limited country coverage. For enterprise use, GeoPostcodes offers verified code data from 1,500+ sources, with regular date-based updates and structured file formats for easy import into MySQL or other systems.

Is GeoNames accurate for all cities and countries?

GeoNames offers broad global coverage, but due to its crowdsourced nature, the quality of city and country data varies. For consistent, verified data across all locations, commercial providers like GeoPostcodes deliver standardized datasets with full coverage, frequent updates, and reliable search, query, and import options into enterprise systems.
