    ZIP codes are not truly areas, but rather a group of deliverable addresses. [2] Some or all of an existing ZIP code's addresses may be reassigned to a new ZIP if there is sufficient growth within a given postal ZIP Code. As many as 3% of ZIP codes undergo change each quarter. Thus, the 5-digit ZCTAs are of limited value in areas of growth or ...

The earliest vector systems, such as the Canadian Geographic Information System, did not manage topological relationships, and problems such as sliver polygons proliferated, especially in operations such as vector overlay.
