Requirements

From composer.json:

• PHP ^8.4
• Laravel ^12 || ^13 (illuminate/contracts, illuminate/support)
• commerceguys/addressing ^2.2 — the vetted ISO 3166 / ISO 4217 reference dataset this package wraps.

No database migration is required: the reference data ships inside the addressing library. Persisting jurisdictions for foreign-key integrity is an optional host concern.
