PALATINE prefixes in area code 847

NANPA records 24 assigned NXX blocks to rate center PALATINE in area code 847, 3.1% 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 (13), BANDWIDTH.COM CLEC, LLC - IL (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). 11 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.
