Group INFINITE has been known to sell out of all their concerts and this encore concert is no different.

On January 16, ticket sales for their world tour encore concert in Seoul began and immediately sold out, causing the server to crash.

All seats sold out and revealed the group's immense popularity.

Woollim Entertainment commented today, "INFINITE's world tour encore concert in Seoul has sold out of all 20,000 seats. We thank all the fans for their amazing support. We were able to create a more upgraded and fun performance this time around. We hope the fans enjoy it as much as we do."

CJ E&M commented, "We were able to see just how INFINITE has grown through their world tour. This concert will truly showcase how global they have become."

They held their first concert in 2012 and continued with a second concert, a small season concert and now their world tour.

Their world tour started back in August and visited 15 countries and 21 cities.

Their encore concert will be on February 28 and March 1 in Seoul.
