各位前辈们，请帮忙看看
意大利铁路官网成功注册之后收到的信息，该怎么理解啊？
YOU SUBSCRIBED
Congratulations XXX XXX （我的姓名）
Registration is complete and your card is now active as a loyalty card.
Payment functions, however, can be activated by making a first recharge after receiving the plastic card, which will be mailed to the address you have indicated.
Here is your CartaFRECCIA code to earn a lot of points, remember to notify every time you buy, make sure it is listed on the ticket.
CartaFRECCIA CODE
XXXXXXXXX （全是阿拉伯数字）
Use your CartaFRECCIA Code asUserID to access the restricted area of the site.
We are sending a e-mail with the temporary card and password that allows you to use all the facilities of your members area.
我的疑问：
remember to notify every time you buy, make sure it is listed on the ticket.
怎么理解这句话呢？
个人翻译理解：记得您每次购票时候，确保这个CartaFRECCIA Code 应该被列明（显示）在车票上。
1， 这样理解 对吗？ 还是有其他意思？
2， 我目前还没有购票的经历，也不知道车票上 是否 明确列明表示有这个CartaFRECCIA Code ？
请指教，谢谢！
