5 Free US Phone Numbers to Make a Test Call with Google Voice
List of valid public United States phone numbers you can call using your Google Voice number to make a test call, keep your account active, or just for fun.

If you just got a US phone number from Google Voice, Tello, or any other provider, you may need to call someone to make a test call.
But what if you don’t want to bother anyone just to test it?
Why Make a Test Call?
There are several reasons to make a test call. Here are some that come to mind:
- Verify that Google Voice is configured correctly
- Confirm your microphone and speaker are working
- Check your caller ID or phone number
- Keep an infrequently used number active
- Test call quality before making an important call
Whatever the reason, making a test call is a good idea before calling real people.
