Overview

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 locations, the geo-codes have come into common usages as P-codes (abbreviated for Place-Code). These terms can be essentially interchanged as long as one recognizes the focus on “position or place” for P-codes. They The 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.
P-codes should be made available as a preparedness activity during the development of the Core CODs (COD-AB and COD-PS). At a minimum, the taxonomy (names and p-codes) should be made available.
P-codes will be required and used at the very start of an emergency and throughout the response. P-codes help with data coordination and provide the framework for most data collection, processing, analysis, and visualization. For instance, P-codes/names are used to create the 3W and monitoring data collection frameworks. They are used to help process data such as when processing country-specific CODs (e.g. putting P-codes in school locations). P-codes are used for analysis such as prioritization matrix or vulnerability matrix. P-codes are also used to visualize humanitarian data in maps and charts as seen in HDX, Snapshots, Bulletins, HNO, etc).
