HARLEYSVL prefixes in area code 215

NANPA records 4 assigned NXX blocks to rate center HARLEYSVL in area code 215, 0.5% of the 783 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 PENNSYLVANIA, INC. (2), NEW CINGULAR WIRELESS PCS, LLC - DC (1), AT&T - LOCAL (1). The earliest assignment on record here is 2001-04-04 and the most recent 2001-04-04. 1 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 codes 267, 445 – overlay codes cover the same geography, so a rate center is served by all of them.
