Unfortunately, at EA Learning, we don’t control the exam vouchers or expiry dates as they are governed by The Open Group and Pearson VUE. Generally, voucher expiration dates cannot be extended as they come with a 12 month validation period. In some circumstances, the Open Group can issue a 3 month extension to your voucher for an administrative fee. You can contact the Open Group via email, togaf-cert-admin@opengroup.org, to request an extension.
