MITCHELL prefixes in area code 605

NANPA records 13 assigned NXX blocks to rate center MITCHELL in area code 605, 1.7% of the 745 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. 7 holders hold those blocks, the largest being QWEST CORPORATION (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SD (3), LEVEL 3 COMMUNICATIONS, LLC - SD (2). The earliest assignment on record here is 2002-05-13 and the most recent 2025-02-17. 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 308, 458, 541, 812 – overlay codes cover the same geography, so a rate center is served by all of them.
