MANASSAS prefixes in area code 703

NANPA records 26 assigned NXX blocks to rate center MANASSAS in area code 703, 3.4% 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. 9 holders hold those blocks, the largest being VERIZON SOUTH, INC. - VA (CONTEL) (15), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (2), LEVEL 3 COMMUNICATIONS, LLC - VA (2). The earliest assignment on record here is 2001-11-01 and the most recent 2023-11-20. 15 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.
