If you change your bank account number or even your bank, you can have your Zoomit documents sent to the new account number. 

Inform each of your senders and ask them to send your Zoomit documents to the new account number from now on

You cannot do this in Zoomit itself. Use the traditional methods (helpdesk, customer services, etc.) to contact your senders. This action can not be done by your bank

Attention: Do this before closing your old account. Otherwise, you will continue to receive documents on your old account number while you have no access anymore.

Attention: Documents already received in Zoomit cannot be transferred to a new account number. Remember to store previously received documents on your PC or another carrier. See our help page Save a document.  As soon as your old account is closed, your documents are not available anymore.
