Phone verification is part of our safety measure. A valid phone number is required to sign up and now you can easily login using your phone number!
Additionally having a valid phone number allows your co-carpoolers to contact you as voice to voice can be a lot easier to communicate matters such as pickup or drop-off point or running a little late etc.
Keep in mind: Wunder does not share your details with any 3rd-parties. Your phone number is also not displayed on your profile and can only be used by another user when you have confirmed to ride with them.
