Offices in your city, with the visit rules for each
Each fund runs its own branches, and visits are often by appointment, sometimes only by phone or video call. For each office you can see which fund it belongs to, how it receives new members and what to have ready before you call.

If you also work across borders, ask whether a special rule or exemption applies to you.
Use the current individual affiliation declaration. Prepare national-register and contact details, activity start date, activity description, enterprise number where applicable, and information about other work or benefits. Confirm supporting documents and submission arrangements with the fund; downloading the form is not affiliation.
