Yes, all vouchers have an expiration date. You MUST take the exam on or before the expiration date. The voucher expiration date cannot be extended. Our regular vouchers typically have an expiration of around 10-11 months. If the product is an EARLY EXPIRATION voucher there will be an expiration date listed on the product page. If the product does not have an expiration date listed anywhere on the product page (in the description) you may assume the product expires in 10-11 months.
