feat(postcodes/GR): bulk-import 1,250 Greece postcodes via ELTA (#1039)#1451
Merged
Conversation
Source: Hellenic Post (ELTA) territory map redistributed via the MentatInnovations/grpostcodes mirror. Each row carries the Greek territory name and approximate centroid coordinates (lat/lng). Ships country-only by design — Greek postcode prefixes do not align cleanly with the 13 peripheries / 7 decentralised administrations (matches the SE/SI/ZA precedent). Refs #1039.

The MentatInnovations source ran every locality through Google Maps and stored whatever Google returned. Four rows came back with non-Greek coordinates: - 10556 (Athens, Plateia Mitropoleos): geocoded to Cyprus (34.92, 33.62) - 20000 (Kentrika Ath): geocoded to null island (0, 0) - 90002 / 90003 (INTERCITY placeholders): geocoded to Washington state, US (47.91, -122.24) Setting lat/lng to null on these rows preserves the postcode and locality_name without misleading downstream consumers about position. A future PR can backfill with a Greek-bbox-validated source.

Summary
Adds 1,250 Greece postcodes covering the full Hellenic Post (ELTA)
territory list, sourced from the
MentatInnovations/grpostcodesmirror. Each row carries the Greek territory name and approximate
centroid coordinates (lat/lng).
locality_namein Greek script.Why country-only
Greek postcode prefixes do not map cleanly to the 13 peripheries
(
Region) or the 7 decentralised administrations represented instates.json— the Athens metro alone spans dozens of substates.Matches the SE/SI/ZA precedent already merged in this repo.
