WOODWARD prefixes in area code 580

NANPA records 11 assigned NXX blocks to rate center WOODWARD in area code 580, 1.5% of the 741 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 SOUTHWESTERN BELL (4), NEW CINGULAR WIRELESS PCS, LLC - IL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OK (2). The earliest assignment on record here is 2001-03-22 and the most recent 2021-08-31. 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 code 515 – overlay codes cover the same geography, so a rate center is served by all of them.
