What is the Extended Postal Code List used for?

• A. To remove codes from the map
• B. To merge CSAs
• C. To highlight extended postal codes on the map
• D. To reorder service areas

Answer: (C)

The main idea is that the Extended Postal Code List is used to visually highlight extended postal codes on the map. This list tells the mapping system which codes should stand out so you can quickly see areas that use extended codes, distinguish them from standard codes, and focus analysis or planning on those zones. It’s especially helpful when you need to emphasize coverage, service areas, or routing considerations that depend on the more granular extended codes. It isn’t used to remove codes from the map, merge CSAs, or reorder service areas—those tasks involve filtering data, combining geographic units, or changing display order, rather than indicating which codes should be highlighted.
