Slovenia numbering plan & how to dial
Dialing into Slovenia means working with an open numbering plan under country code +386: a 2-digit prefix plus a 7-digit subscriber number, 9 digits total. Locally, numbers usually carry a leading "0" that gets dropped when calling Slovenia from outside the country.
With 89% internet penetration, Slovenia is covered by 3 major carriers — Telekom Slovenije, A1 Slovenia, T-2. VoIP is permitted and regulated by AKOS (Agency for Communication Networks and Services). IVR prompts, SMS copy, and business hours here should account for the local language (Slovenian) and currency (EUR).
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 Slovenia from the US requires the 011 exit code ahead of +386 — skip it and the call won't connect.
Keeping the national trunk "0"
That leading 0 on a Slovenia number is for domestic calls only; leave it out when dialing in after +386.
Ignoring the time difference
Slovenia runs on UTC+1. Check local hours before dialing so calls don't land outside business time.
Permitted — AKOS regulated
Regulated by AKOS (Agency for Communication Networks and Services)
- VoIP operators must notify AKOS under the Electronic Communications Act (ZEKom-2).
- Emergency service access (112) is compulsory for all VoIP providers serving Slovenian subscribers.
- GDPR is enforced by the Information Commissioner for all electronic communications providers in Slovenia.

FAQ
Calling Slovenia — frequently asked questions
Twiching rates to Slovenia start at $0.011/min, and calls back from Slovenia to the US start at $0.009/min. Both directions are billed per second rather than rounded up to the nearest minute, on Tier-1 routes throughout.
A full national Slovenia number is 9 digits after the +386 country code — a 2-digit area or mobile prefix plus a 7-digit subscriber number. Getting this length right matters: too few or too many digits and the call simply won't connect.
Yes — Slovenia numbers are often written with a leading domestic "0" that's dropped when dialing in from abroad. Keeping that 0 on an international call is a common reason calls to Slovenia fail to connect.
Calling Slovenia means dialing 011, then +386, instead of the domestic US format — plus accounting for the UTC+1 time difference. Domestic US calls skip both the exit code and the international country code entirely.
The subscriber portion of a Slovenia number is 7 digits, after the country code and area/mobile prefix. That's the part that identifies the specific line once the call has been routed to the right network.
Telekom Slovenije is among the largest networks in Slovenia, and Twiching interconnects directly with it for Tier-1 delivery. Direct interconnects like this are what keep call quality and answer rates consistent instead of relying on lower-tier transit.
