PLANO prefixes in area code 630

NANPA records 3 assigned NXX blocks to rate center PLANO in area code 630, 0.4% 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. 3 holders hold those blocks, the largest being FIRST COMMUNICATIONS, LLC (1), PAETEC ITEL, LLC (1), ILLINOIS BELL TEL CO (1). The earliest assignment on record here is 2009-11-03 and the most recent 2009-11-03. 3 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 214, 331, 469, 641 – overlay codes cover the same geography, so a rate center is served by all of them.
