When you set your pick up location for an uberPOOL ride, a screen will pop up prompting you to enter your intended destination. Your destination can also be entered by clicking the (+) sign that appears next to your pick up address in the app.
Keep in mind that you will be required to enter your destination upon requesting an uberPOOL and will not be able to change the destination once you are matched. If you need to change your destination, you will have to cancel the trip and re-request another uberPOOL.
