CALEDONIA prefixes in area code 262

NANPA records 9 assigned NXX blocks to rate center CALEDONIA in area code 262, 1.4% of the 634 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 UNITED STATES CELLULAR - WI (3), LEVEL 3 COMMUNICATIONS, LLC - WI (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2002-05-29 and the most recent 2002-05-29. 9 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 419, 507, 567, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
