IRVING prefixes in area code 972
NANPA records 90 assigned NXX blocks to rate center IRVING in area code 972, 11.5% 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. 11 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (55), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (8), SOUTHWESTERN BELL TELEPHONE COMPANY - TX (6). The earliest assignment on record here is 2001-05-07 and the most recent 2017-03-27. 51 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, 217, 320, 469 – overlay codes cover the same geography, so a rate center is served by all of them.
