NANPA records 6 assigned NXX blocks to rate center LOSTPNNSUL in area code 734, 0.9% of the 701 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 FRACTEL, LLC (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), LEVEL 3 COMMUNICATIONS, LLC - MI (1). The earliest assignment on record here is 2001-05-10 and the most recent 2021-04-02. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
