To support locale-specific display and validation of addresses, which elements should you store and apply?

• A. Country metadata, locale-aware formatting rules, translations for UI labels, and locale-specific validation rules
• B. Only country names
• C. Only postal codes
• D. User's language preference

Answer: (A)

Handling addresses across locales requires storing and applying a complete set of locale-specific data. This includes country metadata to identify each region and its conventions, locale-aware formatting rules that define the exact order and presentation of address components for display, translations for UI labels so field names appear in the user’s language, and locale-specific validation rules that enforce correct postal code formats and required fields according to local practice. Together, these elements ensure addresses are shown in a familiar format, described with understandable labels, and validated against the local standards users expect. Relying on just country names doesn’t provide enough information to format or validate addresses correctly. Focusing only on postal codes omits the broader structure of an address, which varies by locale. And relying solely on the user’s language preference doesn’t address the necessary formatting and validation logic that differs between regions.
