ITASCA prefixes in area code 630
NANPA records 17 assigned NXX blocks to rate center ITASCA in area code 630, 2.2% of the 782 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 (6), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (3), LEVEL 3 COMMUNICATIONS, LLC - IL (2). The earliest assignment on record here is 2001-04-11 and the most recent 2001-04-11. 13 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 254, 331, 847 – overlay codes cover the same geography, so a rate center is served by all of them.
