AMBRIDGE prefixes in area code 724

NANPA records 7 assigned NXX blocks to rate center AMBRIDGE in area code 724, 0.9% 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. 4 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - PA (2), TELEPORT COMMUNICATIONS AMERICA, LLC - PA (1). The earliest assignment on record here is 2001-05-03 and the most recent 2001-05-30. 6 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 878 – overlay codes cover the same geography, so a rate center is served by all of them.
