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 results should be kept up to date because address data and the underlying street networks can change, and geocoder databases are periodically updated. Re-geocoding when an address is updated ensures the stored coordinates reflect the latest information, while periodic refreshes catch drift over time due to database improvements or new buildings and road changes. Handling this process with privacy and compliance in mind means applying re-geocoding in a controlled way—on edits and on a scheduled basis, with appropriate data safeguards and consent where required.

Storing textual fields alone or never geocoding would prevent the system from benefiting from precise location data for mapping, distance calculations, and routing, and would fail to provide accurate geospatial context. Re-geocoding on updates plus regular refreshes balances accuracy with governance.
