ATLNTIC CY prefixes in area code 640
NANPA records 18 assigned NXX blocks to rate center ATLNTIC CY in area code 640, 13.4% of the 134 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 NEW CINGULAR WIRELESS PCS, LLC - DC (6), OMNIPOINT COMMUNICATIONS ENTERPRISES, LP (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (2). The earliest assignment on record here is 2018-12-24 and the most recent 2026-10-15. 18 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 code 609 – overlay codes cover the same geography, so a rate center is served by all of them.
