TERRELL prefixes in area code 972

NANPA records 7 assigned NXX blocks to rate center TERRELL in area code 972, 0.9% of the 785 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 4 holders hold those blocks, the largest being SOUTHWESTERN BELL (3), METROPCS, INC. (2), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1). The earliest assignment on record here is 2001-10-11 and the most recent 2020-12-22. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 469, 945 – overlay codes cover the same geography, so a rate center is served by all of them.
