Frequently Asked Questions
Is 406 really the only area code in Montana?
It is. Montana sits alongside states such as Wyoming and Alaska that still cover their entire territory with a single area code, in this case 406.
What is the local time in Montana?
Montana keeps Mountain Time (MT), which normally runs 7 hours behind GMT/UTC, or 6 hours behind while Daylight Saving is active.
Can I reach both mobiles and landlines in Montana?
Yes. Intercalling connects to mobiles and landlines across Montana, and in the US the per minute rate is usually the same for either one.
Should I add +1 ahead of 406?
When you are calling from outside the USA, or using our browser dialer, yes. Enter +1 406 and then the local number.
