HEBER SPG prefixes in area code 501

NANPA records 9 assigned NXX blocks to rate center HEBER SPG in area code 501, 1.4% of the 631 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (1), TELEPORT COMMUNICATIONS AMERICA, LLC - AR (1). The earliest assignment on record here is 2001-05-08 and the most recent 2010-01-18. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
