BROWNSDALE prefixes in area code 507

NANPA records 4 assigned NXX blocks to rate center BROWNSDALE in area code 507, 0.5% of the 766 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 ONVOY, LLC - MN (2), MCC TELEPHONY OF MINNESOTA, LLC - MN (1), CITIZENS TELECOM CO MN-FRONTIER CITIZENS COM-MN (1). The earliest assignment on record here is 2002-06-11 and the most recent 2023-05-04. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
