feat(postcodes/ES): bulk-import 8,124 codes via INE/Correos (#1039)#1437
Merged
Conversation
Adds the importer + first run for Spain. Uses the walterleonardo mirror
of INE/Correos's official codigos-postales-municipios mapping.
1. bin/scripts/sync/import_spain_postcodes.py — pipeline reading the
3-column header-less CSV (id, postal_code, municipality_name).
Resolves state via the well-known Spanish postal-prefix to ISO2
convention (01->VI Álava, 28->M Madrid, 08->B Barcelona, ..., 51->CE
Ceuta, 52->ML Melilla). states.json uses license-plate-style codes
(A, B, M, GR, ...) so a hardcoded 52-entry prefix map is the cleanest
resolution path.
2. contributions/postcodes/ES.json — 8,124 unique postcodes with 100%
state_id resolution.
State resolution
- 50 provinces + 2 autonomous cities (Ceuta, Melilla) covered
- Postal prefixes 01-52 are stable since 1980s; map is authoritative
Validation (zero errors across 8,124 records)
- All codes match countries.postal_code_regex (^(\\d{5})\$)
- All FKs resolve, all state_codes agree with state.iso2
- No auto-managed fields present
License & attribution
