There are a number of fourth level domains that can be allocated for US websites.
These are usually restricted as to who can register them - typically Governments, schools, colleges, libraries, and museums.
We present to you the first two tables in this article. The first table gives a list by Domain Format while the second gives a list By Purpose.
Where the [state] element of the domain (url) uses the state abbreviation - we also present to you the State Abbreviations listed by two-letter Abbreviation and by State.
