CONRAD prefixes in area code 406
NANPA records 5 assigned NXX blocks to rate center CONRAD in area code 406, 0.7% of the 754 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 NEW CINGULAR WIRELESS PCS, LLC (3), 3 RIVERS TELEPHONE COOPERATIVE, INC. - MT (1), QWEST CORPORATION (1). The earliest assignment on record here is 2010-10-14 and the most recent 2010-10-14. 5 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 641 – overlay codes cover the same geography, so a rate center is served by all of them.
