Where On Earth Identifiers

Spatial entities provided by Yahoo! GeoPlanet are referenced by a 32-bit identifier: the Where On Earth ID (WOEID). WOEIDs are unique and non-repetitive, and are assigned to all entities within the system. A WOEID, once assigned, is never changed or recycled. If a WOEID is deprecated it is mapped to its successor or parent WOEID, so that requests to the service using a deprecated WOEID are served transparently.
