BREESE prefixes in area code 618

NANPA records 4 assigned NXX blocks to rate center BREESE in area code 618, 0.5% of the 786 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 PEERLESS NETWORK OF ILLINOIS, LLC - IL (1), ILLINOIS BELL TEL CO (1), BANDWIDTH.COM CLEC, LLC - IL (1). The earliest assignment on record here is 2012-10-30 and the most recent 2023-01-11. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
