Under what conditions will extended postal codes that fall outside of an intended CSA boundary receive the CSA assignment of the geography it falls in?

• A. If the stop gets a contingency assignment and there is no Postal Code Override for that zip.
• B. If there is a Postal Code Override for that zip
• C. If the extended code is invalid
• D. If the geography is reassigned

Answer: (A)

When an extended ZIP falls outside a CSA boundary, the system will assign the CSA based on the geography the ZIP resides in only if the stop has a contingency assignment and there is no Postal Code Override for that ZIP. The contingency path acts as a fallback mechanism, letting the stop inherit the CSA from the geographic area it actually sits in, rather than forcing it to the boundary’s CSA. If there is a Postal Code Override, that override takes precedence and the CSA will come from the override rules instead of the geography. An invalid extended code or a geography reassignment would involve different handling and don’t trigger this contingency-based geography-into-CSA mapping.
