There are always new user codes available for these kind of programs, but it’s hard to find codes available for existing users.

If you are a new Uber user click here and create a new Uber account. At the bottom click add promo code and enter matthewh2389 to get $20 credit. You will get $5 off each of your first 4 rides.

If you are an existing user, click here or the payment tab in the app. Go to promo code and enter LOCALFAVORITE for a $10 credit. It will give you $10 off one ride.

It appears to be available for select accounts only. The first time I clicked “add” I got an error. I clicked it again and it went through giving me the credit!
