HAYMARKET prefixes in area code 703

NANPA records 4 assigned NXX blocks to rate center HAYMARKET in area code 703, 0.5% 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. 3 holders hold those blocks, the largest being VERIZON SOUTH, INC. - VA (CONTEL) (2), LEVEL 3 COMMUNICATIONS, LLC - VA (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2002-02-22 and the most recent 2002-02-22. 2 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.
