SNFC JUNPR prefixes in area code 628

NANPA records 14 assigned NXX blocks to rate center SNFC JUNPR in area code 628, 7.3% of the 193 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. 7 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), FRACTEL, LLC (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (2). The earliest assignment on record here is 2016-07-01 and the most recent 2025-01-13. 14 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 415, 650 – overlay codes cover the same geography, so a rate center is served by all of them.
