As I try to keep informed on matters with Italian trains, my understanding has been that the Senior and Young discounted fares on Trenitalia were not available to non-residents of Italy, first because a card needed to be sent to an Italian address, and then even if people had an address to receive it, the request form required Italian document numbers beyond the Codice Fiscale, which can be generated from a program.
Now I've happened upon a discussion in the Rick Steves forum https://community.ricksteves.com/tr...count-train-tickets-on-trenitalia-for-seniors showing a way of getting it: at https://www.trenitalia.com/it/cartafreccia/assistenza_ai_soci.html#6 even if the page is in Italian expand the last point where in English it gives a link to a form that you can print, fill out, and scan as an email attachment to apply for a CartaFreccia that you can receive by email: the form https://www.trenitalia.com/content/...CCIA/Modulo_CartaFRECCIA_residenti_estero.pdf . Note that only the starred fields need to be completed: if born in the USA I entered in country of birth Stati Uniti d'America; for the province code some in that discussion say to use your 2-letter state code, but I spelled out Estero. For date of birth I used the European DD/MM/YYYY format.
They say to allow 45 days to receive a member number, so start this early if you're thinking of booking a train where this could be useful. The Senior (over 60) or Young (under 30) fares are typically comparable to the Super Economy fares but are more like Economy in restrictions, allowing one change of booking with an upgrade to the Base (full) fare. I've applied and will see when I get a response: the key point is to fill out the paper rather than online form if a non-Italian resident.
