When should you re-geocode an address in an Address Management System?

• A. Only at initial creation, never again.
• B. When the address is edited only.
• C. When the address is updated and periodically refreshed, respecting privacy and compliance.
• D. Never geocode coordinates; only store textual fields.

Answer: (C)

Geocoding should be kept current because addresses and the underlying map data can change. Re-geocoding when an address is updated ensures the coordinates, ZIP, and geometry align with the latest data for accurate mapping, routing, and analytics. It's also wise to refresh geocodes on a periodic schedule to benefit from improved base maps, corrected street data, and new geocoding rules, while always respecting privacy and compliance requirements. This means applying appropriate data minimization, access controls, and retention policies so sensitive location data is handled responsibly. The other approaches miss essential needs: geocoding only at creation ignores drift and updates; geocoding only on edits overlooks periodic improvements; and never geocoding coordinates contradicts the purpose of spatial indexing and geospatial features.
