STRATFORD prefixes in area code 806

NANPA records 3 assigned NXX blocks to rate center STRATFORD in area code 806, 0.4% 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. 3 holders hold those blocks, the largest being XIT TELECOMMUNICATIONS & TECHNOLOGY, INC. - TX (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (1). 2 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 codes 515, 559, 580, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
