DOUGLAS prefixes in area code 307
NANPA records 9 assigned NXX blocks to rate center DOUGLAS in area code 307, 1.8% of the 499 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. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - WY (1), STRATUS NETWORKS (1). The earliest assignment on record here is 2001-10-03 and the most recent 2023-12-01. 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 402, 520, 580, 701 – overlay codes cover the same geography, so a rate center is served by all of them.
