"Service unavailable" when attempting to add a United States (US) bank account

If you are receiving the "Service unavailable"-error when adding a bank account for United States (US) domestic wire funding, you are either entering an ACH routing number instead of a wire routing number, or have reached the limit of two bank accounts.

Ensure that you are entering a wire routing number and not an ACH routing number when adding a US bank account, and contact support if you need to remove one or more of your current bank accounts.

Kraken does not currently support ACH bank transfers.
