You will need your Ryanair booking reference which the third-party travel agent should have provided you with. This is a 6-digit code containing a mixture of letters and numbers e.g., ABCD12, which is unique to your booking. If you do not have access to the Ryanair booking reference associated with your booking, you will need to contact the third-party travel agent who made the booking and ask them to provide it to you. You will also need a form of identification with a photo/signature on it (national ID card or passport) and device (e.g., phone, tablet, laptop) with a camera.
