BARRINGTON prefixes in area code 847
NANPA records 15 assigned NXX blocks to rate center BARRINGTON in area code 847, 1.9% 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 (8), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (1). The earliest assignment on record here is 2001-04-02 and the most recent 2026-03-17. 8 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, 603 – overlay codes cover the same geography, so a rate center is served by all of them.
