The ISF organises several tournaments including the 6-a-Side World Championship (for national teams), 6-a-Side Socca Champions League and 7-a-Side Master’s League (for club teams) and continental championships like the 6-a-Side European Championship, and regional tournaments such as the Socca Americup. These events take place in various locations around the world.

ISF football follows specific rules adapted for small-sided formats (5-8 players). Key differences from traditional football include smaller pitch sizes, shorter match durations (typically two 15-minute halves), rolling substitutions, and modified offside rules. The complete rulebook is available in the Socca Rules section of our website.

See Official ISF Rules 2026

Players are selected directly by their national association, as long as the country is an ISF member. Each association manages its own selection process, so interested players should contact their national body for further information.

Any national-level organisation that runs 5, 6, or 7-a-side football leagues can apply to join the ISF.

To join, please visit the ISF Membership section of our website to purchase your country’s membership. Membership is offered across three tiers and is allocated on a first-come, first-served basis for the annual membership period.

Membership is available for all formats, in three packages: Bronze, Silver, and Gold.

Upon successful purchase, your organisation will become the exclusive national operator of your countries team for ISF competitions relevant to your 5-, 6-, and/or 7-a-side membership.

Yes. Subject to availability, an organisation may purchase multiple ISF memberships (5-, 6-, and 7-a-side) for the same country in a single membership year.

ISF national team rights are granted for on a annual purchase basis for 5, 6, or 7-a-side competitions.

Once a country’s membership for a specific category has been purchased for the year, that organisation holds exclusive rights to represent the country in ISF competitions for that category. During this period, no other organisation may enter teams, act on behalf of the country, or hold a membership for the same category. Any interested parties must wait until the following membership year to purchase that category if it becomes available.

However, if a country’s membership has been purchased for one category (E.g., 5-a-side), any remaining categories (such as 6- or 7-a-side) that have not been purchased remain available to buy. These categories are not reserved or restricted unless they have been officially purchased and paid for.

To enter an ISF tournament, organisations must hold an ISF Membership, which is achieved by paying the annual membership fee through the ISF website. Additionally, participation fees are required and may differ based on the tournament.

Yes, LED boards will be available to purchase in advance via the ISF Shop, after completing the sign up for the relevant tournament, and paying your entry fee. This will allow you to provide your sponsor to appear on the board, where we will provide the correct specification. Conditions will apply and this option will be available in three different formats.

Apart from the prestige of being able to call your team ‘World Champions’ or ‘European Champions’ (if you are a country) or ‘the best 6-a-side team in the World’ (if you are a club), we also offer a range of prizes, gifts or cash awards to team that finish in the later stages and win each event. Your team will also receive significant worldwide media coverage.
