DLFTWTARPT prefixes in area code 214

NANPA records 7 assigned NXX blocks to rate center DLFTWTARPT in area code 214, 0.9% 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. 6 holders hold those blocks, the largest being ONVOY, LLC - TX (2), LEVEL 3 COMMUNICATIONS, LLC - TX (1), GRANDE COMMUNICATIONS NETWORKS, INC. - TX (1). The earliest assignment on record here is 2001-08-10 and the most recent 2021-09-14. 7 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, 945, 972 – overlay codes cover the same geography, so a rate center is served by all of them.
