PLANO prefixes in area code 214
NANPA records 17 assigned NXX blocks to rate center PLANO in area code 214, 2.2% 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 FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (4), SOUTHWESTERN BELL TELEPHONE COMPANY - TX (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2003-11-21 and the most recent 2026-10-14. 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 331, 469, 630, 641 – overlay codes cover the same geography, so a rate center is served by all of them.
