Mail from 3F?

If you live with your employer and you do not want to receive mail from 3F, then please contact us and we will try to help you. We can create a contact address elsewhere.

Paying membership to 3F-BJMF without a Danish bank account?

If you do not have an account in a Danish bank and you want to avoid additional costs for making international transfers, contact BJMF and you will be registered in the card payment system. From then on, each time your invoice is generated, you will receive an email with a unique link to the encrypted card payment page. No extra costs, fast and easy.

No CPR number?

If you have not received a cpr.nr, you can not sign up to 3F. But if you work in the construction industry, 3F BJMF will do whatever we can to help you get a cpr.nr.  When or if we are successful, we will back date your membership and the membership dues to the day you first came to BJMF.
