How to dial a number in Liechtenstein from anywhere: the dialling helper.

Test a pattern

Tick the line types you accept, copy the combined pattern, and paste numbers to see which range each one falls in. Numbers are reduced to their national digits first (no spaces, no +423, no trunk prefix 0); nothing leaves your browser.

^(?:(?:6(?:(?:4[5-9]|5\d)\d|6(?:[024-68]\d|1[01]|3[7-9]|7[02]))\d|7(?:[37-9]\d|42|56))\d{4}|(?:2(?:01|1[27]|2[024]|3\d|6[02-578]|9[06])|3(?:[24]0|33|7[0135-7]|8[048]|9[0269]))\d{4})$

Walk the prefixes

Type the first digits of a number in national form, or tap them: the operators holding blocks under those digits, then the block a full prefix falls in. 14 blocks held by 9 operators are on record.

Cheat sheet

Line types and their regular expressions

Match each pattern against the national significant number: digits only, without the trunk prefix 0 and without +423. The patterns follow the national numbering plan and are anchored here.

^(?:(?:6(?:(?:4[5-9]|5\d)\d|6(?:[024-68]\d|1[01]|3[7-9]|7[02]))\d|7(?:[37-9]\d|42|56))\d{4})$

^(?:(?:2(?:01|1[27]|2[024]|3\d|6[02-578]|9[06])|3(?:[24]0|33|7[0135-7]|8[048]|9[0269]))\d{4})$

^(?:8002[28]\d\d|80(?:05\d|9)\d{4})$

^(?:90(?:02[258]|1(?:23|3[14])|66[136])\d\d)$

^(?:870(?:28|87)\d\d)$

^(?:697(?:42|56|[78]\d)\d{4})$

Carrier prefix blocks

The operator each prefix block was allocated to, in national form, from the published allocation records for +423.

Questions developers ask

How many digits does a phone number in Liechtenstein have?

Mobile numbers have 7 or 9 national digits. Fixed line numbers have 7 national digits. That is the national number, without the country code +423 and without the trunk prefix 0.

What is the country code for Liechtenstein?

+423. From abroad, dial your own exit code, then 423, then the national number without its trunk prefix 0. From inside Liechtenstein, the exit code for international calls is 00.

Which prefixes are mobile numbers in Liechtenstein?

Mobile numbers start with 6 or 7 in national form; the mobile regular expression on this page gives the exact ranges (example: 660 234 567). The carrier table shows which prefix blocks were allocated to which operator.

Can a mobile number in Liechtenstein be ported to another carrier?

Not on record. The plan data this page is built from does not list mobile number portability for Liechtenstein, so the carrier a prefix was allocated to is likely, not certainly, the carrier serving the number. Only a live carrier lookup (an HLR or MNP query) confirms it.
