P-codes are unique geographic (geo) identification codes, represented by combinations of letters and/or numbers to identify a specific location or feature on a map or within a database. For a specific place, point, or positional location, the geo-codes have come into common usages as P-codes (abbreviation for Place-Code). These terms can be interchanged as long as one recognizes the focus on “position or place” for P-codes. There can only be only one P-code per administrative unit. They are also used to provide unique reference codes to refer to settlements or administrative units in other datasets.
