Liechtenstein numbering plan & how to dial
Under country code +423, Liechtenstein runs a closed numbering plan — just a 7-digit subscriber number after the country code, no area code required.
3 major networks cover Liechtenstein (Telecom Liechtenstein, FL1, Salt (roaming)), against 98% internet penetration. VoIP is permitted and regulated by AK (Office of Communications, Amt für Kommunikation). Because German is the primary language and CHF the local currency, both should inform IVR scripts, SMS content, and support hours.
Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and cross-border VoIP is widely supported across the region.
Skipping the exit code
Reaching Liechtenstein from the US requires the 011 exit code ahead of +423 — skip it and the call won't connect.
Adding an area code that doesn't exist
Liechtenstein uses a closed plan — dial the +423 country code then the 7-digit subscriber number directly, with no area code.
Ignoring the time difference
UTC+1 governs local business hours in Liechtenstein; confirm the time there before placing the call.
Permitted — AK regulated
Regulated by AK (Office of Communications, Amt für Kommunikation)
- VoIP services are regulated by the AK under the Liechtenstein Communications Act aligned with EEA rules.
- Emergency service access (112) is mandatory for all VoIP operators serving Liechtenstein subscribers.
- As an EEA member, Liechtenstein applies GDPR through the Data Protection Act (DSG).

FAQ
Calling Liechtenstein — frequently asked questions
Liechtenstein is in Europe. Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and cross-border VoIP is widely supported across the region.
Liechtenstein's ISO 3166-1 alpha-2 code is LI, distinct from its dialing code (+423). The ISO code is used in things like domain names and shipping forms, while the dialing code is what actually routes a phone call.
German is the primary language in Liechtenstein — IVR prompts, SMS copy, and support scripts should be written in it for the best response rates. Getting the greeting and menu options right in the local language is often the difference between a caller staying on the line or hanging up.
Liechtenstein uses a closed plan: a single 7-digit subscriber number directly after the country code, with no separate prefix layer. Every number in the country is the same total length as a result.
Liechtenstein's local currency is CHF, which is worth factoring into any pricing or invoicing shown to customers there. Twiching's own per-minute rates to and from Liechtenstein are quoted in USD regardless of the local currency.
The major networks in Liechtenstein are Telecom Liechtenstein, FL1, Salt (roaming). Twiching interconnects with Tier-1 carriers for direct delivery to these networks, rather than routing through cheaper wholesale transit that can degrade call quality.
