Each six-digit Specific Area Message Encoding (SAME) Location Code “PSSCCC” uniquely identifies a specific geographic area. The "P" allows for subdividing or partitioning the area defined by the "CCC" into smaller parts in the case of a very large or uniquely shaped area, or because of widely varying climate, population, or geographic features. The area defined by the “CCC” can be divided into 2 to 9 partitions. Area partitions may be of unequal size and when combined will cover the entire "CCC" area without overlap.
