NEW HAVEN prefixes in area code 502

NANPA records 6 assigned NXX blocks to rate center NEW HAVEN in area code 502, 0.8% of the 735 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 NEW CINGULAR WIRELESS PCS, LLC - GA (2), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2004-03-19 and the most recent 2024-02-13. 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 codes 203, 260, 304, 475 – overlay codes cover the same geography, so a rate center is served by all of them.
