The capacity at the UCD Bowl has been increased due to the unprecedented demand for tickets for the Women's Rugby World Cup.
Defending champions England will get the tournament underway at the UCD Bowl on Wednesday, August 9 when they face Spain on Pool B before New Zealand take on Wales in the opening game of Pool A at 2.45pm.
Hosts Ireland begin their campaign on the same day when they welcome Australia to the UCD Bowl at 7pm with France and Japan's clash at Billings Park the final game of the day.
The pool games will take place across two pitches in University College Dublin - the UCD Bowl and Billings Park - on August 9, 13 and 17 with the top four teams progressing to the semi-finals at Kingspan Stadium in Belfast on Tuesday, August 22.
With all three match days sold out at the UCD Bowl, organisers have taken the decision to increase the capacity to over 16,000, while the capacity at Billings Park is under review.
"When we marked 100 days to go, we advised people to get their tickets fast, and sure enough people moved quick. Having sold out the Bowl on all days, and Billings Park on two match days, we revisited our plans to see how we can meet the ongoing demand," Tournament Director of Women's Rugby World Cup 2017 Garrett Tubridy said.
"We are building additional capacity at the Bowl to meet that demand and those tickets are being released to general sale today. It's great to see that the tournament is capturing the imagination of the public and this is being reflected in demand for tickets. We are still looking at Billings Park but will have more news on that in the coming days.
"As expected, demand from Ireland is particularly strong, and those who are not lucky, or quick enough, to secure a ticket for one of Ireland's pool games can buy tickets for the semi-finals day and finals days at Kinspan Stadium where Ireland will play each day - either in one of the marquee matches or their ranking match, depending on where they rank after the pool stages."
