CHAMBERSBG prefixes in area code 223

NANPA records 6 assigned NXX blocks to rate center CHAMBERSBG in area code 223, 2.4% of the 252 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. 4 holders hold those blocks, the largest being ONVOY, LLC - PA (2), FRACTEL, LLC (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2019-08-14 and the most recent 2024-02-01. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 217, 717 – overlay codes cover the same geography, so a rate center is served by all of them.
