Ukash are changing the process for replacing under 18 vouchers
that have been incorrectly issued by PayPoint outlets. You should
check your voucher is for Over 18 use before leaving the PayPoint
issuing shop. Over 18 vouchers have 001 (UK) or 027 (Ireland) in
digits 7,8 and 9 of the 19-digit Ukash voucher code. The shopkeeper
can replace the voucher immediately if it has been issued
incorrectly. However, if you leave the shop vouchers will only be
replaced using the Ukash Consumer Voucher Replacement process
(
see Ukash FAQs).
