FRISCO prefixes in area code 972
NANPA records 21 assigned NXX blocks to rate center FRISCO in area code 972, 2.7% 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. 8 holders hold those blocks, the largest being SOUTHWESTERN BELL (11), NEW CINGULAR WIRELESS PCS, LLC - IL (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2016-07-11 and the most recent 2022-06-21. 14 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.
