DENTON prefixes in area code 940
NANPA records 79 assigned NXX blocks to rate center DENTON in area code 940, 15.6% of the 506 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. 20 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (19), NEW CINGULAR WIRELESS PCS, LLC - IL (17), GRANDE COMMUNICATIONS NETWORKS, INC. - TX (6). The earliest assignment on record here is 2001-03-09 and the most recent 2026-05-20. 52 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 336, 402, 406, 410 – overlay codes cover the same geography, so a rate center is served by all of them.
