T20I kit
 The Guernsey cricket team is the team that represents the Bailiwick of Guernsey, a Crown dependency in international cricket. They became a member in 2005 and an associate member of the International Cricket Council (ICC) in 2008.
 In April 2018, the ICC decided to grant full Twenty20 International (T20I) status to all its members. Therefore, all Twenty20 matches played between Guernsey and other ICC members after 1 January 2019 have the full T20I status. 
Guernsey played their first T20I against Jersey on 31 May 2019.
 Guernsey has a long rivalry with the neighbouring Channel Island of Jersey, playing an annual encounter against each other known as the inter-insular match since 1950. Guernsey had a run of ten consecutive defeats from 1992 to 2001.
 They made their debut at the European Championship in 2006, and finished in 5th place in Division Two, the tournament being won by Norway. Since then they have won promotion to the T20 Championship Division One.
 International matches are being played by Guernsey outside the above two events also, with matches against Bermuda and Namibia in 2005, and more matches against Bermuda in 2006. Games against France and a tour of Canada were planned for 2007.
 Guernsey placed second at the 2009 Global Division Seven tournament, advancing to Division Six. In Division Six Guernsey finished 4th and therefore remained in Division Six. They came first in the 2011 Division Six tournament, advancing to 2012 ICC World Cricket League Division Five. However, they came third in the Division Five tournament, remaining in the division, before coming 5th and being relegated to Division Six for the 2015 season, winning immediate promotion puts them back in Division Five, where in 2016 they came 3rd, remaining in Division Five.
 Guernsey is ranked 31st in the World and 7th in Europe in the World Cricket League (21 May 2016).
 In September 2018, Guernsey qualified from Group C of the 2018–19 ICC T20 World Cup Europe Qualifier to the Regional Finals of the tournament.

 Performance by Guernsey's cricketers in World Cricket League matches
  
 Guernsey joined Division 2 of the Sussex Cricket League in 2016 after Sussex clubs voted unanimously to allow the island to join the competition, playing as the Guernsey Sarnians.  Guernsey Sarnians cannot be promoted or relegated as they will play less games. Each league team plays ONE match against the Guernsey Sarnians XI. The points from these matches are included in team totals, and the Guernsey Sarnians XI's points are factored (by adjustment of bonus points) to show their relative League position.
