WASKOM prefixes in area code 903

NANPA records 3 assigned NXX blocks to rate center WASKOM in area code 903, 0.4% of the 771 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 T-MOBILE USA, INC. (1), EASTEX TEL. COOP., INC. (1), COMCAST PHONE OF TEXAS, LLC - TX (1). The earliest assignment on record here is 2002-10-30 and the most recent 2009-10-02. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
