TRUMBULL prefixes in area code 203
NANPA records 13 assigned NXX blocks to rate center TRUMBULL in area code 203, 1.7% 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. 6 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (5), NEW CINGULAR WIRELESS PCS, LLC - DC (2), LEVEL 3 COMMUNICATIONS, LLC - CT (2). The earliest assignment on record here is 2001-03-14 and the most recent 2011-03-18. 8 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, 440, 475 – overlay codes cover the same geography, so a rate center is served by all of them.
