BIRCH TREE prefixes in area code 573

NANPA records 13 assigned NXX blocks to rate center BIRCH TREE in area code 573, 1.7% of the 786 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (11), BRIGHTSPEED OF EAST MISSOURI, LLC (1), ONVOY, LLC - MO (1). The earliest assignment on record here is 2004-11-04 and the most recent 2024-08-05. 13 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 235 – overlay codes cover the same geography, so a rate center is served by all of them.
