DLFTWTARPT prefixes in area code 469

NANPA records 10 assigned NXX blocks to rate center DLFTWTARPT in area code 469, 1.3% of the 786 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 (3), LEVEL 3 COMMUNICATIONS, LLC - TX (3), ONE RING NETWORKS, INC. (1). The earliest assignment on record here is 2012-02-17 and the most recent 2020-01-27. 10 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, 945, 972 – overlay codes cover the same geography, so a rate center is served by all of them.
