MCPHERSON prefixes in area code 620

NANPA records 9 assigned NXX blocks to rate center MCPHERSON in area code 620, 1.3% 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), T-MOBILE USA, INC. (1), ONVOY, LLC - KS (1). The earliest assignment on record here is 2001-06-07 and the most recent 2021-06-09. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
