E CHICAGO prefixes in area code 219
NANPA records 22 assigned NXX blocks to rate center E CHICAGO in area code 219, 4.4% of the 495 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 T-MOBILE USA, INC.

The earliest assignment on record here is 2002-02-11 and the most recent 2024-04-30. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
