RIPON prefixes in area code 209

NANPA records 6 assigned NXX blocks to rate center RIPON 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. 6 holders hold those blocks, the largest being CHARTER IP ENABLED SERVICES, LLC (1), PEERLESS NETWORK OF CALIFORNIA, LLC - CA (1), WIDE VOICE, LLC - CA (1). The earliest assignment on record here is 2007-11-14 and the most recent 2022-09-28. 5 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 274, 350, 920 – overlay codes cover the same geography, so a rate center is served by all of them.
