DALE CITY prefixes in area code 703

NANPA records 14 assigned NXX blocks to rate center DALE CITY in area code 703, 1.8% of the 775 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. 7 holders hold those blocks, the largest being VERIZON SOUTH, INC. - VA (CONTEL) (8), METROPCS, INC. (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2005-02-28 and the most recent 2011-11-14. 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 code 571 – overlay codes cover the same geography, so a rate center is served by all of them.
