MARKHAM prefixes in area code 979
NANPA records 3 assigned NXX blocks to rate center MARKHAM in area code 979, 0.7% of the 413 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 GANADO TELEPHONE CO., INC. DBA YK COMMUNICATIONS (1), RICE TELECOM CORPORATION (1), EVOLVE CELLULAR, INC. (1). The earliest assignment on record here is 2008-07-10 and the most recent 2025-03-27. 1 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
