SNRA JUNO prefixes in area code 209

NANPA records 6 assigned NXX blocks to rate center SNRA JUNO 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 ONVOY, LLC - CA (2), COMCAST PHONE OF CALIFORNIA, LLC (1), PACIFIC BELL (1). The earliest assignment on record here is 2004-11-05 and the most recent 2023-06-22. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
