Here is the shortest path to that screenshot:
Go to legacy.usacycling.org using your phone or other mobile device.
Log in to your account using the LOG IN box by clicking on the upper right corner.
Click on the link to the legacy site in the heading at the top of the screen.
Choose the license link in the bar under the banner at the top of the screen.
Click on the Print Authorization to Ride button.
Take a screenshot of this one page. (If you don't know how--look it up! It's easy.) It shows all the info on one screen that you’ll need at a race: license number, racing age, categories by discipline, and current USAC membership status (for 2018). For WSBA members, your jersey number appears in the Chip Numbers field; you’ll also need that number at race registration.
Be sure to take your license information and WSBA numbers to every race!
Storing all this info NOW in one place will save lots of time for you (and everyone else) on race day. USAC is working to improve its apps and encourages members to explore that option as well.
Good luck this season!
