Sri Lanka numbering plan & how to dial
Sri Lanka uses an open numbering plan under country code +94. After the country code, a 2-digit area or mobile prefix is followed by a 7-digit subscriber number, giving a 9-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Sri Lanka from abroad.
Sri Lanka has 54% internet penetration and is served by 3 major mobile networks (Dialog Axiata, Mobitel, Hutch). VoIP is permitted and regulated by Telecommunications Regulatory Commission of Sri Lanka (TRCSL). The local currency is LKR and the primary language is Sinhala, Tamil, which shape IVR prompts, SMS content, and business-hours handling.
Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized effect on answer rates.
Skipping the exit code
From the US you must dial 011 before the +94 country code to reach Sri Lanka.
Keeping the national trunk "0"
That leading 0 on a Sri Lanka number is for domestic calls only; leave it out when dialing in after +94.
Ignoring the time difference
Before dialing Sri Lanka, check the local clock — it runs on UTC+5:30, and off-hours calls tend to go unanswered.

FAQ
Calling Sri Lanka — frequently asked questions
Yes — Sri Lanka is one of 191+ countries in Twiching's directory, with virtual numbers, SIP termination, and Tier-1 routing available. It's part of the same platform used to manage numbers across every other country in the directory.
Colombo is the capital of Sri Lanka. A local +94 number is recognisable to callers there and nationwide, which is part of why presenting local caller ID tends to improve answer rates across the whole country, not just the capital.
No license restriction beyond standard regulation — Telecommunications Regulatory Commission of Sri Lanka (TRCSL) permits VoIP in Sri Lanka for compliant operators. That keeps setup straightforward for a Twiching customer looking to call or text into the country.
The two most common slip-ups are forgetting the 011 exit code before +94, and keeping a domestic leading "0" that should be dropped. Both mistakes result in the call failing to connect rather than reaching the wrong number.
Telecommunications Regulatory Commission of Sri Lanka (TRCSL) is the regulator for Sri Lanka. Twiching routes calls in line with its rules for compliant, licensed termination, rather than relying on unlicensed grey routes that can be blocked or degraded.
Dialog Axiata is among the largest networks in Sri Lanka, 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.
