BLACKBURN prefixes in area code 660
NANPA records 4 assigned NXX blocks to rate center BLACKBURN in area code 660, 0.8% of the 518 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 LEVEL 3 COMMUNICATIONS, LLC - MO (2), EMBARQ MISSOURI, INC. DBA CENTURYLINK - MO (1), ONVOY, LLC - MO (1). The earliest assignment on record here is 2004-05-17 and the most recent 2004-12-30. 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 code 918 – overlay codes cover the same geography, so a rate center is served by all of them.
