Speak the language of the Lake Michigan shore

Up in Northern Michigan, people still pick up for a number they recognize.

From the cherry orchards around Grand Traverse Bay to the harbor in Muskegon, 231 is the code locals have seen on shop signs and boat launch flyers since 1999. Showing it on your caller ID signals that you serve this stretch of the Lower Peninsula, not a call center three states away. For resorts, contractors and outfitters who live on repeat customers, that familiarity is often what gets the call answered.

One code for a long stretch of coastline

231 covers a wide, mostly rural slice of the Northern Lower Peninsula.

The code runs along the western side of the state, taking in Traverse City, Muskegon and the small towns between them. Neighbouring codes like 616 around Grand Rapids and 989 to the east cover different markets, so a 231 number keeps you firmly anchored on the lakeshore. Because the area has no overlay, a 231 number is instantly read as local up and down the coast.

A front desk that never goes home

Allo turns your 231 line into a team member that works every shift.

When you are out on a job site or the season is at its peak, the AI receptionist picks up, answers common questions and captures what the caller needs. Every call is recorded and summarized, so you can read the gist in seconds instead of replaying voicemails. Notes and contacts flow straight into HubSpot, Salesforce or Pipedrive, and you can text customers back from the same number.
