Saudi National Address

Saudi National Address provides an authoritative, reusable source of
Saudi Arabia's administrative geography — regions → cities →
districts — with full Arabic/English translations, ready-to-use dependent
address fields, and a single service that centralises all address logic.

Data is sourced from the
yasseralsamman/saudi-national-address
package and imported into three translatable taxonomy vocabularies
(sna_region, sna_city, sna_district) via a Drush
command or an admin UI.

Key features

• Bilingual taxonomy: ~13 regions, ~4,500 cities and thousands
  of districts, with English (default) and Arabic translations.
• Dependent address fields: attach standard entity reference
  fields to any entity and get a cascading region → city → district experience:
  choosing a region filters the city options, and choosing a city filters the district
  options. A custom selection handler also rejects, on submit, any child that does not
  belong to the selected parent.
• AddressResolver service: the single source of address logic.
  Resolve a full hierarchy from an 11-digit district ID, look up regions/cities/districts
  by their National Address ID, navigate the hierarchy, run typeahead searches, work with
  geo coordinates (nearest city/region, distance), and validate hierarchies. Returns typed,
  language-aware value objects. You can also do Reverse Lookup from LatLng to SNA.
• Idempotent importer: seed or refresh the data with
  drush sna:import (or from Configuration » Regional » Saudi
  National Address), using the Batch API so large datasets do not time out.

Requirements

• Drupal 10+
• PHP 8.1+
• The yasseralsamman/saudi-national-address Composer package composer require yasseralsamman/saudi-national-address
