FAQ

Should I use the registered company name or trading name?

Use the full registered legal name as it appears in official business registers. Trading names should be included in additional seller name fields if needed.

What about company suffixes like GmbH, AG, or UG?

Include the complete legal form (GmbH, AG, UG, etc.) as it is part of the official registered name and required for legal identification.

Can I abbreviate the seller name if it is very long?

The seller name should not be abbreviated as it serves legal identification purposes. If the name exceeds character limits, consider using the additional seller name fields.
