DUMAS prefixes in area code 806
NANPA records 9 assigned NXX blocks to rate center DUMAS in area code 806, 1.2% of the 734 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. 5 holders hold those blocks, the largest being VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (2), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2004-08-09 and the most recent 2021-06-15. 6 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 code 870 – overlay codes cover the same geography, so a rate center is served by all of them.
