BAXTER SPG prefixes in area code 620

NANPA records 5 assigned NXX blocks to rate center BAXTER SPG in area code 620, 0.7% of the 705 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), METROPCS, INC. (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KS (1). The earliest assignment on record here is 2005-02-25 and the most recent 2022-01-31. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
