ana acosta Hi! You should be able to change your email in settings. I will message you the email we have on file and you can let me know if it's correct.
Juan Jose Hi! A good rule of thumb is if a code has a long string of letters and numbers, like ENsSI2988Fmfsv, it's most likely single-use. However, this isn't always the case. I would take a look at the previous validations to see if there is any sign of what would make it a single-use code - maybe a screenshot of an email with the restrictions listed out, or a screenshot of an email that says "For this email only" or something like that.
