ELK GROVE prefixes in area code 847

NANPA records 37 assigned NXX blocks to rate center ELK GROVE in area code 847, 4.7% 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 (22), T-MOBILE USA, INC. (4), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (3). The earliest assignment on record here is 2001-02-20 and the most recent 2001-04-12. 21 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, 279, 916 – overlay codes cover the same geography, so a rate center is served by all of them.
