134 Cities, 31 Counties: The Real Size of Area Code 989
Beyond the city list, area code 989 spans all or part of 31 Michigan counties, making it one of the largest codes covered in this series by land area. Saginaw, Bay, and Midland counties form the core, since the three anchor cities of the Great Lakes Bay Region sit inside their borders.
The Core Counties
Saginaw, Bay, and Midland counties hold the bulk of 989 numbers, covering the three cities that give the Great Lakes Bay Region its name.
The Outer Counties
Gratiot, Tuscola, and dozens of smaller rural counties stretch the coverage area north toward Alpena and west toward Mount Pleasant, each contributing a handful of small towns to the total. That combination of three dense anchor counties and dozens of sparser outer ones is what makes 989's footprint feel so different depending on which part of the region a caller is in.
A 989 Call Just Came In — Here's How to Verify It
Picture this: your phone rings, a 989 number shows up, and because it looks local, you assume it's a neighbor or a familiar business calling. Scammers count on exactly that reaction, spoofing 989 numbers to run vehicle-warranty robocall campaigns that call the same households multiple times a day, and to impersonate Consumers Energy, the utility company that actually serves much of this region. Because area code 989 Michigan includes so many smaller, tight-knit communities, that kind of local-sounding impersonation works more often than it should.
- Never confirm account numbers, payment details, or personal information to an unexpected caller.
- Hang up and call the company or agency back using a number from its official website.
- Search the exact number online to see if others have reported it as a scam.
- Report confirmed scam calls to the FTC and block the number afterward.
989 vs. Michigan's Other Area Codes: 517, 313, and 906
Michigan runs multiple geographic area codes, and comparing area code 989 against its neighbors makes it easier to tell at a glance whether a number is coming from the Great Lakes Bay Region or somewhere else. That distinction matters for anyone comparing local phone numbers before choosing one for a growing team.
- 989 covers Saginaw, Bay City, Midland, and north-central Michigan.
- 517 covers Lansing and south-central Michigan, the code 989 split from.
- 313 covers Detroit and the immediate metro core.
- 906 covers the entire Upper Peninsula, further north still.
Placed side by side, 989 and 906 end up bordering each other at the top of the Lower Peninsula, which means a call from the far north of 989's territory and a call from the southern edge of 906 can come from towns barely an hour apart.
The 2001 Split That Created 989 Out of Old 517 Territory
A common assumption is that 989 must cover less ground than the older 517 code it split from, since newer codes usually take the smaller share. The opposite happened here: when regulators split the original 517 territory on April 7, 2001, Lansing and Jackson kept the 517 name, but 989 inherited the much larger northern and central portion of the map, including the entire Great Lakes Bay Region.
- The split took effect on April 7, 2001, after 517's numbers neared exhaustion.
- 989 covers more counties today than the 517 code it was carved out of.
- Growth in cell phone adoption in the late 1990s drove the need for the split.
- No further splits or overlays have been added to 989 since 2001.
Eastern Time, Every Time: What 989's Clock Means for Your Calls
Every number under area code 989 runs on Eastern Time, the same clock used across most of Michigan and the East Coast. That single detail matters for anyone scheduling calls, appointments, or deliveries with a Great Lakes Bay Region contact from a different part of the country.
- Eastern Standard Time (EST, UTC-5) runs from early November through early March.
- Eastern Daylight Time (EDT, UTC-4) covers the rest of the year, including summer.
- Callers from the Midwest should plan for a one-hour difference against 989 numbers.
- Callers from the West Coast should plan for a three-hour difference against 989 numbers.
- Callers from the UK or Western Europe should plan for a five-hour difference in the other direction.
