Geographical and postal classification

The United States of America consists of 50 federal states, whereby Alaska and Hawaii, as well as the politically connected territories of Puerto Rico and Guam are outside the core countries (CONUS, Continental U.S.).

The next largest administration unit in most of the states is the county (also called parish or borough). There are 3,143 counties, the average number per federal state is 62. One county has an average population of approximately 100,000 inhabitants. There are also extreme examples like Los Angeles County with nearly 10 million inhabitants. The most meaningful statistical value is therefore the median. Using this value, each country has around 25,000 inhabitants.

Each of the approximately 30,000 postal areas of the US Postal Service has an individual number in accordance with the ZIP code (Zone Improvement Plan). After the first digit, the USA can be classified into 10 zip code zones.

Street Directories

The U.S. Street Directory Reference File, which is called the CASS file (CASS stands for “Coding Accuracy Support System”), is a file with every single U.S. address in it. There are two separate CASS files, both of which our partner has. Through the combination of both files, 0.5% to 1% more addresses can be certified in comparison to the use of only one file.

Data Protection

Data ProtectionCustomers must be informed that their data is being used for the purpose of dialogue marketing. The use of the data is not allowed if the individual has objected to the terms of use. Further restrictions are also present for certain institutions such as financial services as well as individual state laws.

U.S. companies must comply with the standards and principles of Safe Harbor. By doing so, these companies are in compliance to the principles of the European Union data protection laws.  Safe Harbor is recognised by the European Union as an adequate data protection standard. Therefore, by being Safe Harbor certified, U.S. companies are permitted to exchange data with European Union member states without any problems.

Opt-out / opt-in: An opt-out option is possible when an individual wishes for his or her data not to be stored. Each person also has a right to access and correct stored data. Companies with their own websites are obligated to protect the accessibility of the user data. Sensitive information such as religion, race, political party affiliation, health, and sexual orientation are all examples of opt-in possibilities.

Postal Service

The United States Postal Service (USPS) is an independent agency of the United States government responsible for providing postal service. It has monopoly on certain postal services. Due to the postal monopoly, competitors are not allowed to deliver non-urgent letters and may not use U.S. mail boxes at residential and commercial destinations. The USPS employs approximately 600,000 workers. DHL also has a presence in the U.S.

Founded in 1917, DMA today represents companies from dozens of vertical industries in the USA and 48 other nations, including nearly half of the Fortune 100 companies, as well as nonprofit organisations.
