BAY CITY prefixes in area code 989

NANPA records 29 assigned NXX blocks to rate center BAY CITY in area code 989, 4.0% 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. 16 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (10), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (4), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-01-25 and the most recent 2024-10-16. 15 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 codes 503, 534, 715, 971 – overlay codes cover the same geography, so a rate center is served by all of them.
