DESPLAINES prefixes in area code 847

NANPA records 32 assigned NXX blocks to rate center DESPLAINES in area code 847, 4.1% 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 (18), LEVEL 3 COMMUNICATIONS, LLC - IL (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - IL (3). The earliest assignment on record here is 2001-08-31 and the most recent 2004-01-08. 18 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 224 – overlay codes cover the same geography, so a rate center is served by all of them.
