DALLAS prefixes in area code 214
NANPA records 363 assigned NXX blocks to rate center DALLAS in area code 214, 46.2% 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. 26 holders hold those blocks, the largest being SOUTHWESTERN BELL (252), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (26), LEVEL 3 OF TELECOM OF TEXAS, LLC - TX (17). The earliest assignment on record here is 2001-04-24 and the most recent 2026-03-03. 196 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, 503, 570, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
