Over 70,000 tickets have already been sold for the Millennium Stadium fixture and with an in-form Wales facing Ireland this weekend, the WRU are expecting tickets to sell-out.
Supporters in Wales have shown their appetite for international rugby is as strong as ever, with the WRU announcing before Christmas of a sell-out for Wales' finale clash against France at the Millennium Stadium.
While tickets are still available for Wales against Scotland and the clash with Italy on Saturday, 10 March, fans are advised to get their tickets now to avoid disappointment.
Tickets are available online at wru.co.uk and ticketlineuk.com or from the telephone hotline 02920 230130.
"It would be great to think we will be playing in front of three packed out full houses at the Millennium Stadium for those home fixtures, so hopefully the fans will react positively to the news that tickets are still available," said Jenkins.
"We have the Ireland game on Sunday as our sole focus at the moment, but a full house in Cardiff the following week is certainly something to look forward to."
