As a general rule, the deposit guarantee applies to all institutions that are members of the FGDR, including those operating as on-line banks. Banks increasingly offer remote banking services.
Contact your bank to find out whether the online services offered to you are provided under a trademark created within a banking institution working under another trademark, and which one. In fact, the benefit of the deposit guarantee scheme of up to €100,000 per customer, per institution applies only once within the same banking institution operating under several trademarks. To verify your coverage under the deposit guarantee scheme, check the bank code number shown on your bank account identification document.
All accounts with the same "bank code" are added together under the €100,000 ceiling since they are held by the same banking institution.
