In Sweden, the area codes are, including the leading 0, two, three or four digits long, with larger towns and cities having shorter area codes permitting a larger number of telephone numbers in the eight to ten digits used (including the leading '0').

The longest subscriber numbers have eight digits (only in the Stockholm area).

The first automatic telephony in Sweden was operating in 1924 within a small area in Stockholm.

Area codes were introduced around 1935 for usage in automatic national telephony.

According to the postal and telecommunication services supervising authority Post- och Telestyrelsen, it seems possible that Sweden will adopt a closed numbering plan in the future.
