DALLAS CTR prefixes in area code 515
NANPA records 4 assigned NXX blocks to rate center DALLAS CTR in area code 515, 0.7% of the 578 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. 3 holders hold those blocks, the largest being ONVOY, LLC - IA (2), BANDWIDTH.COM CLEC, LLC - IA (1), QWEST CORPORATION (1). The earliest assignment on record here is 2011-11-23 and the most recent 2022-01-14. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
