If you have any questions or problems with the buyer reference at federal level, you can reach the responsible contact person by email via our contact form.
Please note that companies or invoice issuers do not generally need their own buyer reference, not even to implement the obligation to exchange invoices electronically between companies (B2B) that will apply from 1 January 2025. The Federal Ministry of Finance is responsible for legal questions regarding invoicing in the B2B sector.
