SHAMROCK prefixes in area code 806
NANPA records 4 assigned NXX blocks to rate center SHAMROCK in area code 806, 0.5% of the 734 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1), SOUTHWESTERN BELL (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2002-03-12 and the most recent 2023-01-20. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
