What is the role of reverse geocoding in address validation?

• A. Reverse geocoding converts addresses into coordinates to save space.
• B. It validates syntax of street numbers.
• C. It standardizes address formats.
• D. Converts coordinates into a human-readable address to verify alignment with stored data and catch inconsistencies.

Answer: (D)

Reverse geocoding in address validation is turning coordinates back into a readable address to verify that the stored address matches the actual location. This helps detect mismatches or inconsistencies between what’s on file and where the coordinates point, improving data integrity for routing and deliveries. It’s not about saving space by converting addresses to coordinates (that’s forward geocoding). It’s also not merely checking street-number syntax or standardizing the address format, which are separate validation and normalization tasks.
