- Sign up with a VoIP carrier.

You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 734 number. If you already have a 734 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Michigan sometimes can’t accept inbound ports of 734 numbers due to 911 routing rules.
