The following is a list of the highest-income ZCTAs in the United States. ZCTAs or ZIP Code Tabulation Areas are the census equivalent of ZIP codes used for statistical purposes. The reason why regular ZIP codes are not used is because they are defined by routes rather than geographic boundaries.

The annually renewed CASS certification is based on delivery point codes, ZIP codes, and ZIP+4 codes. Adoption of a CASS certified software by software vendors allows them to receive discounts in bulk mailing and shipping costs. They can benefit from increased accuracy and efficiency in those bulk mailings, after having a certified database.
There are generally two widely accepted versions of a postal code: a ZIP code and a ZIP + 4 code. Established in 1963, ZIP codes are the most common and recognizable postal code used by the USPS.
ZIP Code data is an integral part of dealer / store locator software on many websites, especially brick-and-click websites. This software processes a user-input ZIP Code and returns a list of store or business locations, usually in the order of increasing distance from the center of the input ZIP Code.
ZCTAs are not developed for ZIP codes that comprise only a small number of addresses. [3] Several ZCTAs represent ZIPs that no longer exist due to realignment by the USPS. There are approximately 42,000 ZIP Codes and 32,000 ZCTAs. The reason that there is not one ZCTA for every ZIP Code is that only populated areas are included in the Census ...
They are based on the assumption that the figure of the Earth is an oblate spheroid, and hence are more accurate than methods that assume a spherical Earth, such as great-circle distance. The first (direct) method computes the location of a point that is a given distance and azimuth (direction) from another point.
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...
