RED DEL prefixes in area code 507
NANPA records 5 assigned NXX blocks to rate center RED DEL in area code 507, 0.7% 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. 4 holders hold those blocks, the largest being REDWOOD COUNTY TEL. CO. (2), MCC TELEPHONY OF MINNESOTA, LLC - MN (1), NEW ULM TELECOM, INC. DBA NU-TELECOM - MN (1). The earliest assignment on record here is 2009-11-03 and the most recent 2010-06-17. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
