E ST LOUIS prefixes in area code 618

NANPA records 14 assigned NXX blocks to rate center E ST LOUIS in area code 618, 1.8% 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. 5 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (10), PAETEC ITEL, LLC (1), METROPCS, INC. (1). The earliest assignment on record here is 2006-06-19 and the most recent 2021-12-30. 8 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 code 730 – overlay codes cover the same geography, so a rate center is served by all of them.
