A code in the “shares ground” column is an overlay: it covers the same territory rather than a different part of Arizona, which is why local calls there are dialled as ten digits.

Which codes share the same ground

Arizona has 1 group of codes that overlay one another: the codes inside a group cover the same territory rather than different parts of the state, so local calls there are dialled as ten digits.

480 602 623

520 and 928 have no overlay: each is the only code serving its own territory.
