GRANDPRARI prefixes in area code 972
NANPA records 134 assigned NXX blocks to rate center GRANDPRARI in area code 972, 17.1% 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. 13 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (45), SOUTHWESTERN BELL (38), SPOK, INC. (14). The earliest assignment on record here is 2004-08-02 and the most recent 2023-08-08. 72 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 214, 469, 945 – overlay codes cover the same geography, so a rate center is served by all of them.
