I've entered wrong birth date

[suyeon]

HI, I'm suyeon.

I purchased two tickets.
932874312305/494554014444
I changed the date of birth of two people.
Is there a problem with the train ride?
Could you fix the date of birth of two people?
I will wait for your reply.
Thank you.

Hello @suyeon 

Thank you for your request.

Are the dates of birth completely false or is it just a number? If it is a single number, you can travel with these tickets. Otherwise, you must purchase new tickets and then complete the cancellation form here: https://www.sbb.ch/en/travelcards-and-tickets/buying-options/refund-request.html

I wish you a nice afternoon.

Best regards,
JulieL
