CEDARBURG prefixes in area code 262
NANPA records 14 assigned NXX blocks to rate center CEDARBURG in area code 262, 2.2% 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. 6 holders hold those blocks, the largest being WISCONSIN BELL INC (5), ONVOY, LLC - WI (3), LEVEL 3 COMMUNICATIONS, LLC - WI (2). The earliest assignment on record here is 2001-12-10 and the most recent 2023-09-13. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
