Can I Request More than One Uber Driver for Large Parties?

No, not at this time.  It’s not possible to request more than one ride from a single account.

If your party cannot be accommodated by a single vehicle, have multiple people in your group request rides. We offer vehicle options accommodating up to 6 people in many cities.

If no one else in your group has an Uber account, you can invite them to sign up from the main menu of your app. As a bonus, both you and your friend will receive the referral promotion.
