GREENVILLE prefixes in area code 618

NANPA records 4 assigned NXX blocks to rate center GREENVILLE 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. 3 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (2), MCC NETWORK SERVICES, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - IL (1). The earliest assignment on record here is 2001-12-06 and the most recent 2021-02-05. 4 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 207, 252, 270, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
