DAHLGREN prefixes in area code 540
NANPA records 8 assigned NXX blocks to rate center DAHLGREN in area code 540, 1.0% of the 786 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. 4 holders hold those blocks, the largest being VERIZON SOUTH, INC. - VA (CONTEL) (5), NEW CINGULAR WIRELESS PCS, LLC - DC (1), FRACTEL, LLC (1). The earliest assignment on record here is 2001-08-16 and the most recent 2020-07-14. 5 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 618, 826 – overlay codes cover the same geography, so a rate center is served by all of them.
