Of course, the easiest way to score Amtrak points is to add your Guest Rewards account number to your booking information when purchasing train tickets. (There's a field for it in the passenger details section of the booking window.) Then all you need to do is watch the points add up.

You can add your Amtrak Guest Rewards number to an existing reservation in three primary ways. The most efficient method is through the Amtrak Mobile App or website: log in to your account, go to "Find Reservation" using your confirmation number, and look for the "Modify" or "Add Loyalty Number" option. Alternatively, you can call 1-800-USA-RAIL and provide your reservation number to an agent who can manually link your profile. Finally, you can speak to a ticket agent at any Amtrak station or even ask the conductor on board (though this is less reliable for point accrual). It is vital to add your number before you travel, as retroactively claiming points after a trip is a more tedious process involving a 12-month limit and physical ticket receipt verification. If you book while logged into your account, the number is automatically applied, ensuring you earn 2 points for every $1 spent, plus any applicable tier bonuses you might have in 2026.
