Iceland phone number validator
How the phone number format works
- Format
- Iceland phone number in national or international (+354) format
- Example
- +3546111234
Things to watch for
- Accepts national or international (E.164, e.g. +354...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$An Icelandic phone number is 7 digits, with no area code and no trunk prefix — one of the shortest, simplest numbering plans in Europe. Mobile numbers typically start with 6, 7, or 8 (611 1234); geographic numbers start with 4 or 5 (555 1234). Converting to international form is pure addition: +354 goes in front of the same 7 digits, nothing dropped or rearranged, because Iceland never adopted a trunk zero to begin with.
How this validator works
Type the 7 digits alone (6111234) or with the country code (+3546111234); this tool checks the length and leading-digit range against Iceland’s real numbering plan using Google’s libphonenumber, entirely in your browser. Because there’s no trunk prefix to strip, the most common error isn’t a leftover 0 after +354 — it’s simply the wrong digit count, since Iceland’s population is small enough that 7 digits comfortably covers the whole country with no regional splitting.
What a pass doesn’t tell you
A pass confirms the 7 digits match a valid Icelandic mobile or geographic pattern — it doesn’t confirm the SIM is active or the landline connected. A correctly-shaped number is not proof it currently reaches anyone.
Scope: useful for catching a missing digit, an extra digit, or a wrongly-added 0 before an Icelandic number reaches a form or SMS gateway — not a substitute for a real lookup or verification service.

phone number FAQ
How many digits does an Icelandic phone number have?
Exactly 7, for both mobile and landline, with no area code and no trunk prefix at all — the international form is simply +354 followed by those same 7 digits, nothing added or stripped.
How can I tell an Icelandic mobile number from a landline?
By the first digit: mobile numbers typically start with 6, 7, or 8, while geographic (landline) numbers start with 4 or 5 — both are 7 digits total, so the leading digit distinguishes them, not the length.
Does a valid Icelandic number check mean it belongs to someone right now?
No. It only confirms the 7 digits match a real Icelandic numbering pattern under Fjarskiptastofa's plan — it can't confirm the SIM or line is currently active, which needs a carrier lookup this free tool doesn't perform.
