1. Check when you placed your order
If you bought the gift voucher, you can cancel your gift voucher order within 30 minutes of completing the order.
If you didn't buy the gift voucher yourself, you'll need to contact the person who bought it and get them to contact ASOS to cancel it.
2. Contact us
If that timescale has passed, and the gift voucher hasn't been used or associated with an account, get in touch with our Customer Care Team.
We'll cancel it for you or if it's because of a mistake in the email address, we'll change it for you and send you another one
