The County of Zeeland did not include the region of Zeelandic Flanders which was part of Flanders; conversely, the modern Province of Zeeland does not include Sommelsdijk, historically part of the County of Zeeland.
Zeelandi krahvkond ei hõlmanud Zeelandi Flandria piirkonda, mis oli Flandria osa; teisalt, praegune Zeelandi provints ei sisalda Sommelsdijki, mis oli ajalooliselt Zeelandi krahvkonna osa.
