S3 is the fare class inventory, you need the fare basis used for your flight.
How to find,
1) call and ask
2) if purchased from united.com, your first booking e-mail has it (not the ticketing e-mail)
This will be a code typically such as XXxxXXXX for discount economy fares
XX is one or two letters, the first will be S in your case
xx will be 1 to 2 digit number, this is the advance purchase requirement
XXXXX will be 3-5 letters, probably one is N (non-refundable)
Note to really know the advance purchase requirement you will need the full fare rules, but the above is a shortcut that works most of the time.
