• Eingetragenes Einzelunternehmen (e.U.): Sole trader registered in Commercial Register (Firmenbuch).

• GmbH / FlexCo / AG: Incorporated companies. Requires Firmenbuchauszug and verification of all UBOs holding >25% shares.

• OG / KG / Verein: Partnerships or registered non-profit associations (Verein with ZVR number).

2. Single vs. Multi-Person Verification Rules

• Einzelunternehmen: 1 person needed (yourself). Passport/ID + Meldezettel / bank statement (< 3-6 months).

• GmbH / Corporate: Under EU 5th AML directives, Stripe requires identifying and verifying the Account Representative AND all Ultimate Beneficial Owners (UBOs) holding >25% of company shares or serving as co-directors (Geschäftsführer).
