feat(postcodes/HU): 3,569 Magyar Posta codes (#1039)#1486
Merged
Conversation
Adds the full Magyar Posta + KSH Helységnévtár postal-code dataset joined by ferenci-tamas/IrszHnk (Feb 2026 refresh). Why --- Closes the HU gap on issue #1039. The single-file CSV from the ferenci-tamas mirror joins the official Magyar Posta workbook with the KSH gazetteer, giving postcode + settlement + sub-district + megye in one row. Coverage -------- - 3,569 codes / 100% state FK resolution - All 19 megyék + Budapest covered (20 of 43 CSC HU iso2 entries) - Cities of county rank (Pécs, Szeged, Debrecen, ...) are CSC-only iso2 entries; the source authoritatively reports megye, so those cities resolve to their containing megye State FK strategy ----------------- 20-entry hand-curated SOURCE_TO_ISO2 handles two name drifts: - 'főváros' (lit. "the capital") -> CSC 'BU' Budapest - 'Csongrád-Csanád' (2020 rename) -> CSC older 'CS' Csongrád County License ------- Repo has no LICENSE file. Upstream is official Hungarian government open data (Magyar Posta + KSH). Tier 5 per #1039 license-tier policy (free redistribution permitted, no formal licence). Each row: source: "magyar-posta-via-ferenci-tamas". Validation ---------- - python3 -m py_compile passes - 100% regex match (^\d{4}$) - 100% state_id valid + state.country_id == 99 + state_code agrees - No auto-managed fields (id, created_at, updated_at, flag) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

ferenci-tamas/IrszHnk— joins Magyar Posta workbook with KSH Helységnévtár (Hungarian Central Statistics Office gazetteer)IrszHnk.csv(semicolon-delimited)State FK strategy
The CSV's
Vármegye.megnevezésecolumn gives the megye/county name. CSC has 43 HU iso2 entries (19 megyék + Budapest + 23 cities of county rank); since the CSV authoritatively reports megye, we map to those 20 county-level entries via a hand-curatedSOURCE_TO_ISO2.Two name drifts handled:
'főváros'(lit. "the capital") → CSCBUBudapest'Csongrád-Csanád'(2020 rename) → CSC olderCS"Csongrád County"Cities of county rank (Pécs, Szeged, Debrecen, ...) resolve to their containing megye since the source has no city-of-county-rank flag in the postcode dataset.
