DALE CITY prefixes in area code 571
NANPA records 29 assigned NXX blocks to rate center DALE CITY in area code 571, 4.5% of the 639 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 METROPCS, INC. (11), NEW CINGULAR WIRELESS PCS, LLC - DC (4), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (3). The earliest assignment on record here is 2002-10-02 and the most recent 2026-08-06. 29 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 703 – overlay codes cover the same geography, so a rate center is served by all of them.
