CHILTON prefixes in area code 920

NANPA records 6 assigned NXX blocks to rate center CHILTON in area code 920, 0.8% of the 785 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (2), METRO SOUTHWEST PCS, LLP (1), UNITED STATES CELLULAR - WI (1). The earliest assignment on record here is 2002-03-20 and the most recent 2005-10-04. 6 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 254 – overlay codes cover the same geography, so a rate center is served by all of them.
