CLARENDON prefixes in area code 806

NANPA records 5 assigned NXX blocks to rate center CLARENDON in area code 806, 0.7% 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 VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2002-10-11 and the most recent 2015-07-01. 3 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 870 – overlay codes cover the same geography, so a rate center is served by all of them.
