README

cboxdk/laravel-geo — a canonical geography reference for Laravel: countries, subdivisions and currencies bound to stable ISO codes, resolved deny-by-default, and carrying the tax-relevant attributes that billing and tax engines build on. A dependency-light framework library — every capability sits behind a contract you bind, mock or replace.

This is the shared jurisdiction primitive for the Cbox portfolio. Identity (org addresses), billing (invoice address, seller entities) and the tax engine all bind to the same jurisdiction keys, so nothing downstream matches on free text.

Why it exists

A tax or billing engine must never fuzzy-match a country name or guess a rate from a ZIP. Everything has to bind to a stable, validated jurisdiction key. This package provides that key — ISO 3166-1 alpha-2 countries, ISO 3166-2 subdivisions, ISO 4217 currencies — sourced from the vetted commerceguys/addressing dataset, with one layer added on top: the tax profile of each jurisdiction.

use Cbox\Geo\Contracts\JurisdictionRepository;
use Cbox\Geo\ValueObjects\CountryCode;
use Cbox\Geo\ValueObjects\SubdivisionCode;

$geo = app(JurisdictionRepository::class);

$dk = $geo->find(new CountryCode('DK'));
$dk->currency;                      // "DKK"
$dk->taxProfile->regimeModule;      // "eu-vat"
$dk->taxProfile->isEuMember;        // true
$dk->isResolvedForTax();            // true — national regime

$us = $geo->find(new CountryCode('US'));
$us->needsSubdivision();            // true — sub-federal, a state is required
$us->taxProfile->requiresRooftop;   // true — rooftop geocoding needed for rates

$ca = $geo->find(new CountryCode('US'), new SubdivisionCode('US-CA'));
$ca->subdivisionName;               // "California"

$geo->find(new CountryCode('ZZ'));  // null — deny-by-default, never a guess

The tax profile

Each modelled jurisdiction carries structural, slow-moving facts — not rates (those live in the tax engine's data feeds):

Sub-federal is deliberately split from rooftop: Canada stacks at province level (a subdivision is enough), while the US stacks below the state and needs rooftop geocoding. National VAT/GST regimes (EU, UK, CH, NO, AU, NZ, MX) need neither.

Design

• Contracts-first. Depend on Contracts\JurisdictionRepository; the default binding wraps the ISO dataset. Swap or persist the data without touching callers.
• No forced migration. The reference data ships inside the library; persisting jurisdictions for FK integrity is an optional host concern.
• Deny-by-default. An unknown country, an unknown subdivision, or a subdivision that does not belong to its country all resolve to null.
