TULARE prefixes in area code 559
NANPA records 25 assigned NXX blocks to rate center TULARE in area code 559, 3.2% of the 785 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. 11 holders hold those blocks, the largest being PACIFIC BELL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (4), NEW CINGULAR WIRELESS PCS, LLC (4). The earliest assignment on record here is 2002-03-21 and the most recent 2026-05-07. 22 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 605 – overlay codes cover the same geography, so a rate center is served by all of them.
