I am trying to book a trip from Paris to Nice for me and 1 other traveler. I cannot book online without the pass cover number. If someone with Eurail support could supply this that would be very helpful. Thank you!

You should be able to book by phone at SNCF. No need of Pass Cover Number.
Press #85 for English, no booking fees, reservations are sent via e-mail.
You need to contacted Customer Support through this form and ask for the Pass Cover Number.
Customer Support is currently overloaded with requests so you will probably have to be patient to get help. Please let Customer Support know what date your travel will start so that they can prioritise your request correctly.
