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 converts geographic coordinates back into a human-readable address. In address validation, this step acts as a check to ensure the coordinates you have actually correspond to the expected street, city, and postal code. By turning the coordinates into an address and comparing it with the stored or entered address, you can reveal inconsistencies such as data entry errors, outdated records, or geocoding mismatches where the coordinates point to a nearby location. This approach helps confirm that the stored address and the real-world location align, which is more reliable for validation than merely checking syntax or formatting.
