Question 1

How to validate addresses with CommerceGuys Addressing in a Symfony project?

Accepted Answer

Use the AddressFormatConstraint and CountryConstraint from the library with Symfony Validator. First validate the country code, then the address fields, leveraging predefined patterns and subdivisions for automated checks.

Question 2

CommerceGuys Addressing vs geocoder-php for address handling?

Accepted Answer

CommerceGuys Addressing focuses on postal address formatting, validation, and static international data, while geocoder-php is for geocoding coordinates. Choose based on whether you need address manipulation or location services.

Question 3

How to format addresses for shipping labels internationally?

Accepted Answer

Use the PostalLabelFormatter with the origin country code to differentiate domestic and international mail. It uppercases fields as needed and adds country names in both local and English per UPU guidelines.

Question 4

Does CommerceGuys Addressing support real-time address verification APIs?

Accepted Answer

No, it uses static data for validation. For real-time verification, you'd need to integrate external APIs like Google Places or national postal services alongside this library.

Question 5

How to handle complex subdivisions like in Brazil with this library?

Accepted Answer

Use the SubdivisionRepository to access hierarchical data (e.g., states and municipalities). The repository provides methods to fetch all levels, as shown in the Brazilian states and Ceará example.

Question 6

CommerceGuys Addressing or a custom database for e-commerce addresses?

Accepted Answer

CommerceGuys Addressing is better for standardizing international handling without reinventing the wheel, but for simple, single-country setups, a custom database might be lighter and easier to maintain.
