Membership

Biënto’s club year runs from 1 January to December 31. The membership fee is dependent on the member’s age.

Membership fee

As soon as we have received your membership fee, you will be registered at the KNBSB (Royal Netherlands Baseball and Softball Federation) and be issued a membership number. Once you are registered at the Federation, you will be covered under their liability insurance. Without membership number issued by the Federation, you are ineligible to participate in competitions. The Federation fee depends on your age and is included in your Biënto membership fee.
