EVANSTON prefixes in area code 847

NANPA records 22 assigned NXX blocks to rate center EVANSTON in area code 847, 2.8% 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. 7 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (14), PAETEC ITEL, LLC (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2001-02-09 and the most recent 2009-11-03. 12 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 224, 307 – overlay codes cover the same geography, so a rate center is served by all of them.
