addressing

A PHP 8.0+ addressing library, powered by CLDR and Google's address data.

Manipulates postal addresses, meant to identify a precise recipient location for shipping or billing purposes.

Features:

• Countries, with translations for over 150 locales. Powered by CLDR v47.
• Address formats for over 200 countries
• Subdivisions (administrative areas, localities, dependent localities) for 60 countries
• Both latin and local subdivision names, when relevant (e.g: Okinawa / 沖縄県)
• Formatting, in HTML or plain text.
• Validation via symfony/validator
• Zones

Address formats and subdivisions were initially generated from Google's Address Data Service, and are now owned and maintained by the library.

Data model

The address interface represents a postal address, with getters for the following fields:

• Country code
• Administrative area
• Locality (City)
• Dependent Locality
• Postal code
• Sorting code
• Address line 1
• Address line 2
• Address line 3
• Organization
• Given name (First name)
• Additional name (Middle name / Patronymic)
• Family name (Last name)

Field names follow the OASIS eXtensible Address Language (xAL) standard.

The interface makes no assumptions about mutability. The implementing application can extend the interface to provide setters, or implement a value object that uses either PSR-7 style with* mutators or relies on an AddressBuilder. A default address value object is provided that can be used as an example, or mapped by Doctrine (preferably as an embeddable).

The address format provides the following information:

• Which fields are used, and in which order
• Which fields are required
• Which fields need to be uppercased for the actual mailing (to facilitate automated sorting of mail)
• The labels for the administrative area (state, province, parish, etc.), locality (city/post town/district, etc.), dependent locality (neighborhood, suburb, district, etc) and the postal code (postal code or ZIP code)
• The regular expression pattern for validating postal codes

The country provides the following information:

• The country name.
• The numeric and three-letter country codes.
• The official currency code, when known.
• The timezones which the country spans.

The subdivision provides the following information:

• The subdivision code (used to represent the subdivision on a parcel/envelope, e.g. CA for California)
• The subdivision name (shown to the user in a dropdown)
• The local code and name, if the country uses a non-latin script (e.g. Cyrilic in Russia).
• The postal code pattern (if different from the one on the address format).

Subdivisions are hierarchical and can have up to three levels: Administrative Area -> Locality -> Dependent Locality.

Formatters

Addresses are formatted according to the address format, in HTML or text.

DefaultFormatter

Formats an address for display, always adds the localized country name.

PostalLabelFormatter

Takes care of uppercasing fields where required by the format (to facilitate automated mail sorting).

Requires specifying the origin country code, allowing it to differentiate between domestic and international mail. In case of domestic mail, the country name is not displayed at all. In case of international mail:

1. The postal code is prefixed with the destination's postal code prefix.
2. The country name is added to the formatted address, in both the current locale and English. This matches the recommendation given by the Universal Postal Union, to avoid difficulties in countries of transit.

Validator

Address validation relies on the Symfony Validator library.

Checks performed:

• All required fields are filled in.
• All fields unused by the country's format are empty.
• All subdivisions are valid (values matched against predefined subdivisions).
• The postal code is valid (country and subdivision-level patterns).

Zones

Zones are territorial groupings often used for shipping or tax purposes. For example, a set of shipping rates associated with a zone where the rates become available only if the customer's address belongs to the zone.

A zone can match countries, subdivisions (states/provinces/municipalities), postal codes. Postal codes can also be expressed using ranges or regular expressions.

Examples of zones:

• California and Nevada
• Belgium, Netherlands, Luxemburg
• Germany and a set of Austrian postal codes (6691, 6991, 6992, 6993)
• Austria without specific postal codes (6691, 6991, 6992, 6993)

Integrations
