National numbers in Iceland are seven digits long and generally written in the form xxx xxxx or xxx-xxxx and the E.123 format specifies +354 xxx xxxx from abroad since the country code is +354.
There are no area codes in this closed numbering plan and the international call prefix is 00. Numbers of mobile phones tend to begin with either 6xx xxxx, 7xx xxxx or 8xx xxxx, while land line numbers start with 5xx xxxx (in Reykjavík) or 4xx xxxx (the country side).
