BRIDGEPORT prefixes in area code 475
NANPA records 25 assigned NXX blocks to rate center BRIDGEPORT in area code 475, 8.6% of the 292 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. 11 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS, INC. - CT (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CT (5), ONVOY, LLC - CT (4). The earliest assignment on record here is 2011-08-29 and the most recent 2025-08-06. 25 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 203, 256, 304, 308 – overlay codes cover the same geography, so a rate center is served by all of them.
