Identity document
Other forms of officially accepted identification include the driver's license and the birth certificate. However, these are accepted only in limited circumstances and cannot take the place of the ID Card in most cases. The ID Card is mandatory for dealing with government institutions, banks or currency exchange shops. A valid passport may also be accepted, but usually only for foreigners.
Identity document
The following documents are generally considered valid (varying a little, since no law lists them): Nordic driving licence, passport (often only from EU and EFTA), national ID card from EU, Norwegian ID card from banks and some more. 
There is no ID card for anyone except bank ID card (normally printed on the reverse of a credit card). To get a bank ID card either a Nordic passport or another passport together with Norwegian residence and work permit is needed.
