It is necessary to have a collateral account at the Deutsche Bundesbank to be able to use MACCs.

If such an account has already been set up, there are only a few steps that need to be taken to be able to submit credit claims using the MACCs application:

1. the completed contact form needs to be sent by email to the support team credit claims;
2. all required participation documents must be signed with a legally binding signature and submitted by post;
3. the mandatory customer test needs to be carried out following registration in the MACCs test environment;
4. the MACCs users need to be registered in the Deutsche Bundesbank’s ExtraNet;
5. the registration needs to be approved by the Deutsche Bundesbank. 

Further information on registering for ExtraNet can be found under the menu item “User management”.
