GRANGER prefixes in area code 515

NANPA records 4 assigned NXX blocks to rate center GRANGER in area code 515, 0.7% 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. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - IA (2), CENTURYLINK COMMUNICATIONS, LLC (1), QWEST CORPORATION (1). The earliest assignment on record here is 2011-05-10 and the most recent 2022-02-22. 4 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 507, 509, 512, 737 – overlay codes cover the same geography, so a rate center is served by all of them.
