If you have forgotten your InterCity account password you can reset it here. If you have forgotten your account number, that's okay - just enter your email address and we'll get you sorted.
You don't have to be a InterCity member to make a booking online - when you get to the Passenger Details page, simply leave the login details blank and fill in your passenger details. If you're not an account holder but would like to sign up you can do so at this point.
