ALGONA prefixes in area code 515

NANPA records 8 assigned NXX blocks to rate center ALGONA in area code 515, 1.4% of the 578 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1), QWEST CORPORATION (1). The earliest assignment on record here is 2002-10-30 and the most recent 2021-12-14. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
