EAST TAWAS prefixes in area code 989

NANPA records 9 assigned NXX blocks to rate center EAST TAWAS in area code 989, 1.2% of the 723 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (3), ONVOY, LLCV - MI (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2004-04-16 and the most recent 2025-01-28. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
