How buying a 406 number works

Pick any number above, or search the full 406 inventory.
Sign up for a Phone2 plan (from $7/month on annual billing). The number is included, with no one-time purchase fee.
Start calling and texting immediately from the mobile, desktop, or web app.

Unlike number marketplaces that sell 406 numbers for $99 or more one-time, Phone2 includes the number with the phone service itself. 30-day refund guarantee, and you can port the number out any time.
