By convention the area id can be calculated from an existing OSM way by adding 2400000000 to its OSM id, or in case of a relation by adding 3600000000 respectively. Note that area creation is subject to some extraction rules, i.e. not all ways/relations have an area counterpart (notably those that are tagged with area=no, and most multipolygons and that don't have a defined name=* will not be part of areas).
