What is the area code for Colombo, Sri Lanka?

Colombo's landline area code is 011, dialled as 0 + 11 inside Sri Lanka. From abroad you drop the trunk 0 and dial +94 11, so a Colombo number written 011 234 5678 becomes +94 11 234 5678 internationally.

How many digits is a Sri Lankan phone number?

A Sri Lankan number is 10 digits when dialled domestically: the trunk 0, a 2-digit area code, and a 7-digit subscriber number (0 + AA + nnnnnnn). Internationally it is written +94 followed by the 9-digit national number, with the trunk 0 removed.

How do I write a Sri Lankan phone number in international format?

Drop the leading 0 and add +94. So the landline 045 222 3344 in Ratnapura becomes +94 45 222 3344, or +94452223344 in compact E.164 form. The same rule applies to mobiles: 077 123 4567 becomes +94 77 123 4567.

What does +94 mean and how do I dial a Sri Lankan landline from abroad?

+94 is Sri Lanka's ITU country calling code. To call a Sri Lankan landline from another country, dial your international access prefix (00 or +), then 94, then the area code without its 0, then the number, for example +94 81 234 5678 reaches a Kandy line.

Which city uses the 081, 091, or 021 area code?

081 is Kandy (Central Province), 091 is Galle (Southern Province), and 021 is Jaffna (Northern Province). Each geographic code covers the main city and nearby towns dialled on the same exchange, 081 also serves Peradeniya, Katugastota, and Gampola.

Are Sri Lankan area codes two or three digits?

The area code itself is two digits (11 for Colombo, 81 for Kandy). It is dialled as three digits domestically because the national trunk prefix 0 is placed in front, so you see 011 or 081. Internationally the 0 is dropped, leaving +94 11 or +94 81.

Why doesn't a 07X mobile number have an area code?

Numbers starting 070 to 078 are mobile, not geographic. A mobile number isn't tied to a fixed location, and because Sri Lanka has mobile number portability, a 07X prefix no longer reliably identifies the operator either. This finder flags mobile numbers instead of inventing a region.

Where do these area codes come from and how current are they?

Every code is reconciled against the TRCSL National Numbering Plan and the Sri Lanka Telecom regional dialling directory. The 29 geographic codes here were last verified on 2026-07-08. Any code that could not be confirmed against those sources was left out rather than guessed.

Area codes follow the TRCSL National Numbering Plan, cross-checked against the SLT regional dialling directory. International formatting follows ITU-T E.164. Reconciled on 2026-07-08. A code missing or wrong? Email [email protected].

How it works

Sri Lanka uses a 10-digit open numbering plan published by the Telecommunications Regulatory Commission of Sri Lanka (TRCSL). A geographic (landline) number is made of three parts dialled back to back:

The national trunk prefix 0, dialled before any domestic call.
A 2-digit area code (AA) that identifies the region, 11 for Colombo, 81 for Kandy, 91 for Galle.
A 7-digit subscriber number (nnnnnnn) assigned by the exchange.

Put together, a domestic number is 0 AA nnnnnnn, exactly 10 digits, for example 081 234 5678. To convert to international form the finder follows ITU-T Recommendation E.164: drop the national trunk 0, prepend the country code +94, and keep the remaining 9-digit national significant number. So 081 234 5678 becomes +94 81 234 5678 and, compacted to E.164, +94812345678.

When you type letters, the tool runs a place-to-code lookup across a curated table of city names, districts, nearby towns, and common spelling variants, with a small fuzzy tolerance so galla still finds Galle. When you type digits, it strips spaces, hyphens, brackets, and any +94, 0094, or trunk 0, then reads the first two digits of the national number as the area code. Numbers in the 07Xrange are recognised as mobile, which, under Sri Lanka's number portability, map to no fixed region, and short codes such as 1919 are flagged as out of scope. This is a pure table lookup and string transformation: no estimates, and no data leaves your browser.

Each geographic code in the table is reconciled against the TRCSL numbering plan and the Sri Lanka Telecom regional dialling directory. Where a code could not be confirmed against both, it was omitted rather than guessed.

Worked examples

Place lookup, Colombo

Colombo

Query is letters → place-to-code lookup.
Match: Colombo → area code 11.
Domestic dial code: 0 + 11 = 011.
International code: +94 11.
A sample line 011 234 5678 → +94 11 234 5678 → E.164 +94112345678.
Digit check: 0 (1) + 11 (2) + 2345678 (7) = 10 national digits. ✓

Reverse number lookup, Ratnapura freelancer

045 222 3344

Query is digits → number lookup.
Strip trunk 0 → national number 45 222 3344 (9 digits).
First two digits 45 → Ratnapura (Sabaragamuwa Province).
Local: 045 222 3344.
International: +94 45 222 3344 → E.164 +94452223344.
This is the form to put on an Upwork or invoice contact field. ✓

Edge case, mobile number rejected

077 123 4567

Strip trunk 0 → national number 771234567.
First digit is 7 → this is the 07X mobile range.
Mobile numbers aren't tied to a region, so no district is invented.
Because of number portability, the 07X prefix no longer names the operator either.
Result: “This is a mobile number, not a landline area code.” ✓
