When migrating to a new locale, under what circumstance should re-geocoding be performed?

• A. Always re-geocode for all addresses
• B. Re-geocode if necessary to align coordinates with new locale rules
• C. Re-geocode only if the user asks
• D. Never re-geocode after initial geocoding

Answer: (B)

When you move to a new locale, the rules and reference data that the geocoding system uses can change. Different regions may have different address formats, boundary definitions, postal code mappings, and even preferred coordinate reference datasets. Because of these shifts, coordinates that were calculated under the old locale’s rules might not align correctly with the new locale’s expectations. The best approach is to re-geocode if necessary to align coordinates with the new locale rules. This means you don’t automatically re-run geocoding for every address, but you do reprocess those records where the locale change could affect their interpretation or placement. This keeps the geographic data accurate and consistent with the new locale’s standards, while avoiding unnecessary processing. Automatically re-geocoding all addresses is wasteful and can introduce changes where none are needed. Waiting for a user’s request can leave data misaligned with the locale, and never re-geocoding after the switch ignores the fact that locale-specific reference data has changed. Re-geocoding when required by the locale change balances accuracy with efficiency.
