DRIGGS prefixes in area code 208

NANPA records 5 assigned NXX blocks to rate center DRIGGS in area code 208, 0.6% of the 785 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. 2 holders hold those blocks, the largest being COLUMBINE TELCO DBA SILVER STAR COMMUNICATIONS (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - ID (1). The earliest assignment on record here is 2005-06-21 and the most recent 2019-07-17. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
