GALT prefixes in area code 209

NANPA records 9 assigned NXX blocks to rate center GALT in area code 209, 1.1% 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. 6 holders hold those blocks, the largest being ONVOY, LLC - CA (2), BANDWIDTH.COM CLEC, LLC - CA (2), PACIFIC BELL (2). The earliest assignment on record here is 2014-04-24 and the most recent 2021-11-09. 8 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 350, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
