Minnesota's number of unknown callers spikes during snowstorms and tax season. You can check the area code first—218, 320, 507, 651, 763, 952—and if it's not local but familiar, use a reverse phone lookup. Never answer calls that start with 900 or similar premium numbers. If the caller claims to be the IRS, hang up and call the Minnesota Department of Revenue directly.
