GAA Sliotar Information

The 2026 List of Approved Smart and Match Sliotar Licensees (subject to change) can be downloaded at the bottom of this page.

GAA Smart Sliotar

A chip is embedded in the core of each Smart Sliotar which can be read by the Foireann app on a mobile phone and is used for sliotar verification purposes primarily in Senior, U20 and Minor (U17) Inter-County Official Games.

The GAA Smart Sliotar project aims to ensure that approved Sliotar Licensees adhere to the Sliotar specifications set out in the GAA Official Guide and that approved sliotars perform on a consistent basis.

In an effective regulatory context, the Association seeks to address illegal use of the official GAA logo and to ensure ethical production and supply chain practices as determined by the World Federation of the Sports Goods Industry (WFSGI).

The Smart Sliotar was used initially in the 2022 U20 Hurling Championships and has been used consistently since the 2023 Allianz Hurling Leagues and All-Ireland Senior Championships.

GAA Match Sliotar

Match Sliotars are all other sliotars, other than Smart Sliotars, which are produced by GAA Licensees, meet GAA specifications and can be used in official games.

Please note that all Match Sliotar licensees have begun the phasing-out process of the production of white-coloured sliotars and commenced the production of Fluorescent Yellow/High-Vis sliotars instead.

It is the recommendation of the GAA’s Sliotar, Hurley and Helmet Work Group, having conducted significant research into the matter in terms of optimal performance, visibility and contrast, that commencing on January 1st, 2024, all hurling games at all levels from Minor (U17) and above, should use a Fluorescent Yellow/High-Vis sliotar from a GAA Sliotar Licensee.
