WILLMAR prefixes in area code 320

NANPA records 18 assigned NXX blocks to rate center WILLMAR in area code 320, 3.5% of the 511 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MN (6), QWEST CORPORATION (3), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-02-26 and the most recent 2023-02-10. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
