ARGYLE prefixes in area code 940

NANPA records 9 assigned NXX blocks to rate center ARGYLE in area code 940, 1.8% 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. 6 holders hold those blocks, the largest being GRANDE COMMUNICATIONS NETWORKS, INC. - TX (3), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), LEVEL 3 COMMUNICATIONS, LLC - TX (1). The earliest assignment on record here is 2021-06-10 and the most recent 2023-12-22. 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 218, 235, 319, 518 – overlay codes cover the same geography, so a rate center is served by all of them.
