That's right.

It's not the case. This is an unlock Subregion ID (SID) for maps. It works in conjunction with the RID. When creating a map, it allows you to specify smaller sections of the product that may be unlocked in MapSource or BaseCamp rather than unlocking the whole region (ie to divide the region into smaller subregions). In this case, the unlock code will unlock only the maps that belong to that region and subregion pair.
