SO PITTSBG prefixes in area code 423
NANPA records 7 assigned NXX blocks to rate center SO PITTSBG in area code 423, 0.9% of the 764 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 BANDWIDTH.COM CLEC, LLC - TN (2), PAETEC ITEL, LLC (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TN (1). The earliest assignment on record here is 2011-11-28 and the most recent 2023-05-18. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
