MANASSAS prefixes in area code 571
NANPA records 41 assigned NXX blocks to rate center MANASSAS in area code 571, 6.4% 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. 14 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (10), NEW CINGULAR WIRELESS PCS, LLC - DC (7), ONVOY, LLC - VA (6). The earliest assignment on record here is 2001-06-25 and the most recent 2026-10-20. 41 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.
