How would you handle internationalization with address component order differences?

• A. Store canonical components with locale-sensitive formatting rules and format addresses per country on display using localization data.
• B. Store final formatted strings for all locales.
• C. Ignore locale differences and use a single format.
• D. Store only postal codes and assemble address at runtime.

Answer: (A)

The main idea is to separate the actual address data from how it’s shown to users, using a canonical set of address components and locale‑specific formatting rules. Store the core components—such as street, locality, region, postal code, and country—in a consistent structure, then format them for display according to the user’s locale or country using localization data. This lets you assemble the address in the correct order and with the right separators for any region.

This approach is best because it keeps data clean and reusable while enabling proper, country‑specific presentation. If you need to support a new country or language, you only update the formatting rules rather than creating new preformatted strings or changing the stored data. It also makes validation and downstream processing (like mailing label generation) more reliable, since you always have the individual components available.

Storing final formatted strings for every locale is impractical and hard to maintain. It balloons the amount of data, makes updates tedious, and doesn’t adapt well if components change or if user locale shifts.

Ignoring locale differences and using a single format leads to misordered components and unreadable addresses for many regions, which defeats the purpose of internationalization.

Storing only postal codes and assembling an address at runtime provides insufficient data to reconstruct a full, correctly structured address and loses flexibility for display and validation.
