LOMBARD prefixes in area code 630
NANPA records 37 assigned NXX blocks to rate center LOMBARD in area code 630, 4.7% 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. 10 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (17), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - IL (4), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (4). The earliest assignment on record here is 2001-04-02 and the most recent 2007-03-14. 23 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 code 331 – overlay codes cover the same geography, so a rate center is served by all of them.
