HUGHSON prefixes in area code 209

NANPA records 6 assigned NXX blocks to rate center HUGHSON in area code 209, 0.8% of the 784 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. 5 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), BANDWIDTH.COM CLEC, LLC - CA (1), IP HORIZON LLC (1). The earliest assignment on record here is 2002-09-19 and the most recent 2016-11-28. 6 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 350 – overlay codes cover the same geography, so a rate center is served by all of them.
