==Outbound WATS==
For Outbound WATS, the United States was divided into geographical Bands 0 through 5. Band zero was intrastate calling and bands 1 through 5 (or 6) were interstate calls that were progressively further from the originating number.<ref>{{cite magazine|title=WATS was built for Philip Carey (and you too) |type=advertisement |author=Cincinnati Bell |url=https://books.google.com/books?id=FesCAAAAMBAJ&pg=PA63 |pages=63–64 |magazine=Cincinnati Magazine |date=April 1971}}</ref> Historically, the higher band number carried a higher price per month or per minute. These lines could be used for outbound long-distance only; not local. In the U.S., interstate WATS lines could not be used for intrastate calls, and vice versa. With wider availability of inexpensive long distance using regular business lines, OutWATS service became obsolete late in the 20th century.
