How do I fill in my bank account information correctly?

Whichever bank you have, you should only enter four digits as the routing number. If you have Swedbank, for example, omit the fifth digit altogether. Then fill in the account number as usual without spaces, dots or dashes. If you have a Nordea personal account, your routing number is 3300, and you fill in the account number according to YYMMDDXXXX.
