Postal code to coordinates

Converts lists of postal codes to representative coordinates with place names and admin divisions from a bundled offline dataset, flagging every code it cannot match.

Paste codes to resolve them to points.

Coordinates publish as-is from the bundled dataset: the representative point for the code, not an address, and never interpolated. The bundled starter set carries a handful of sample rows per country, not the full GeoNames export, which the page credits under CC BY 4.0; a dated snapshot also means new codes can be missing and retired ones can linger. Unresolved codes keep their row with empty coordinates and a reason, so exports line up one to one with what you pasted. Nothing is sent to a geocoder.
