A code in the “shares ground” column is an overlay: it covers the same territory rather than a different part of Texas, which is why local calls there are dialled as ten digits.
Which codes share the same ground
Texas has 6 groups 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.
254, 325, 361, 409, 432, 806, 830, 915, 936, 940, 956 and 979 have no overlay: each is the only code serving its own territory.
