POPLAR BLF prefixes in area code 573

NANPA records 16 assigned NXX blocks to rate center POPLAR BLF in area code 573, 2.0% 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (6), NEW CINGULAR WIRELESS PCS, LLC - IL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (2). The earliest assignment on record here is 2001-05-24 and the most recent 2022-09-01. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
