The European Free Trade Association (EFTA) is founded by Austria, Denmark, Norway, Portugal, Sweden, Switzerland and the United Kingdom, to promote closer economic cooperation and free trade in Europe.

In 1962, Norway applied for membership in the European Economic Community (EEC) with fellow EFTA members Ireland, Denmark, and the United Kingdom having applied to join the previous year. When France rebuffed the United Kingdom's application the following year, accession negotiations with Norway and the other countries were also suspended because of the strong economic ties between them. This happened again in 1967.[17]
Norway completed its negotiations for the terms to govern a Norwegian membership in the EEC on 22 January 1972. Following an overwhelming parliamentary majority in favour of joining the EEC in early 1972, the government decided to put the question to a popular
referendum, scheduled for September 24 and 25.
[18] The result was that 53.5% voted against membership and 46.5% for it.
[17] The
Norwegian Labour Party government led by
Trygve Bratteli resigned over the outcome of the referendum, and a coalition government led by
Lars Korvald took over.
[19]
Norway entered into a trade agreement with the Community following the outcome of the referendum. That trade agreement remained in force until Norway joined the
European Economic Area on 1 January 1994.
[20]
On 28 November 1994, a second referendum was held, narrowing the margin but yielding the same result: 52.2% opposed membership and 47.8% in favour, with a turn-out of 88.6%.
[21] There are currently no plans to resume their current application, which is currently frozen.
Norway was an associate member of the
Western European Union until the organisation terminated in 2011.
Edit.
More bollocks to correct. Norway was never in the EEC.

You must be confusing it with the Western European Union.
