ANTIOCH prefixes in area code 847

NANPA records 4 assigned NXX blocks to rate center ANTIOCH in area code 847, 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), LEVEL 3 COMMUNICATIONS, LLC - IL (1), COMCAST IP PHONE, LLC (1). 2 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, 864, 925 – overlay codes cover the same geography, so a rate center is served by all of them.
