WATERBURY prefixes in area code 203
NANPA records 52 assigned NXX blocks to rate center WATERBURY in area code 203, 6.6% of the 784 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 SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (23), NEW CINGULAR WIRELESS PCS, LLC - DC (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CT (6). The earliest assignment on record here is 2001-07-02 and the most recent 2011-03-10. 30 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 402, 475, 802 – overlay codes cover the same geography, so a rate center is served by all of them.
