Which network is 077 in Sri Lanka?

077 is a Dialog Axiata prefix. Along with 076 and 074, it is one of Dialog's allocated 07X mobile ranges under the TRCSL numbering plan. Any number that normalises to 077XXXXXXX belongs to Dialog by original allocation.

Is 072 Dialog or Hutch?

072 is Hutch, not Dialog. It was originally an Etisalat prefix; after Hutchison Telecom acquired Etisalat Lanka in 2018, the 072 and 078 ranges became Hutch numbers. So a 072 number is on the Hutch network.

What network uses 075 in Sri Lanka?

075 is Dialog. The range was originally allocated to Airtel Lanka, which amalgamated into Dialog Axiata on 30 August 2024 with Dialog as the surviving entity; Dialog is now the licensee of the Airtel brand, so a 075 number sits on the Dialog network even where it is sold as Airtel. Dialog's other consumer prefixes are 074, 076 and 077.

How do I know if a Sri Lankan number is Dialog or Mobitel?

Check the first three digits. 070 and 071 are SLT-Mobitel; 074, 076 and 077 are Dialog. Paste the number above and the tool reads the prefix for you, ignoring spaces, dashes and the +94 country code.

Can a Sri Lankan mobile prefix change with number portability?

Once Mobile Number Portability (MNP) goes live, yes — a subscriber could keep their number, including the prefix, while switching to a different network. MNP is licensed but not yet operational (targeted around late 2026), so today the prefix still reliably identifies the operator.

What are all the mobile prefixes in Sri Lanka?

The allocated 07X mobile prefixes are: 070 and 071 (SLT-Mobitel), 072 and 078 (Hutch), and 074, 075, 076 and 077 (Dialog — 075 being the former Airtel range). Codes such as 073 and 079 are inside the mobile range but are not currently assigned to any operator. Sri Lanka has three mobile networks, not four: Airtel is a Dialog-licensed brand, not a separate operator.

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

Drop the leading 0 and add the +94 country code. For example, 077 123 4567 becomes +94 77 123 4567. The tool shows both the local and +94 forms with copy buttons once you enter a valid number.

Does this tool detect a fixed-line or landline number?

It recognises that a number is not a mobile and says so instead of guessing a network. Fixed-line numbers use geographic area codes such as 011 (Colombo) or 081 (Kandy) rather than 07X. To find the city and district behind a landline number, use the Sri Lanka Telephone Area Code Finder.

Does this tool tell me who owns a number?

No. It identifies only the network an original prefix was allocated to — never the subscriber. Reverse lookup of a Sri Lankan mobile owner is not publicly available and would breach privacy, so it is deliberately out of scope.

Is this an official TRCSL tool?

No — it is a free independent tool built on the public TRCSL Sri Lanka Numbering Plan and cross-checked against Wikipedia's per-prefix table. The regulator, the TRCSL, is the authority that allocates all numbering resources; sources are linked below.

Sri Lanka Mobile Number Prefixes — 07X Operator Code List

Every 07X mobile prefix TRCSL has allocated, and the operator it went to: 070 and 071 to SLT-Mobitel, 072 and 078 to Hutch, 074 to 077 to Dialog. Paste a number and it is matched against the same table, with clean local and +94 dialing formats. Sri Lanka has three mobile networks — Airtel is a brand Dialog is licensed to use, not a fourth operator. For the question “which network is 070, 071, 074, 075?” in more depth, including landline area codes, see the Sri Lanka phone number lookup. No signup, no ads, sources cited below.

This shows the prefix's original network

Mobile Number Portability (MNP) is licensed in Sri Lanka but not yet live (targeted around late 2026, repeatedly deferred). Until it goes live, the prefix reliably identifies the operator. Once MNP is live, a number could keep its prefix while running on a different network, so treat this as the original TRCSL allocation, not a live SIM check.

Allocations from the TRCSL Sri Lanka Numbering Plan, cross-checked with Wikipedia. Landline numbers (e.g. 011 for Colombo) are area codes, not 07X mobile prefixes, and are out of scope for this tool.

How it works

Every Sri Lankan phone number is assigned by the Telecommunications Regulatory Commission of Sri Lanka (TRCSL) under a 10-digit Open Numbering System. Mobile numbers all sit in the 07X range, where the first three digits are a fixed operator code. Because Mobile Number Portability is not yet live, that code still reliably tells you which network a number belongs to. The tool is a pure prefix lookup — no arithmetic, no API, and nothing leaves your browser.

Normalise the input. Spaces, dashes and brackets are stripped. A leading +94, 0094 or bare 94 is converted to a single leading 0, and a 9-digit 7XXXXXXXX gets its 0 restored.
Validate length and range. The result must match ^07\d{8}$ — exactly 10 digits starting with 07. Anything shorter, longer, or not starting with 07 (a landline like 011, for instance) is rejected with a specific reason.
Extract the operator code. The first three digits (07X) are the operator code allocated by TRCSL.
Look up the operator in the static allocation table below. Prefixes inside 07X that TRCSL has not assigned (073, 079) are flagged as unassigned rather than guessed.

The allocation table is taken from the TRCSL Sri Lanka Numbering Plan and cross-checked against the Wikipedia “Telephone numbers in Sri Lanka” table:

070 → SLT-Mobitel
071 → SLT-Mobitel
072 → Hutch (previously Etisalat)
074 → Dialog
075 → Dialog (originally Airtel Lanka, which amalgamated into Dialog Axiata on 30 August 2024; Dialog is the licensee of the Airtel brand)
076 → Dialog
077 → Dialog
078 → Hutch (previously Etisalat / Lanka Cellular)

As a correctness check, the tool resolves each valid number two ways — an O(1) prefix map and an independent linear scan of the same table — and both must agree before an operator is shown. The result also carries a dated LAST_VERIFIED marker (2026-09-22) so you know when the ranges were last checked against the source.

Worked examples

Input

0771234567

Normalise: no separators, already 10 digits → 0771234567
Validate: matches ^07\d{8}$ → valid mobile
Operator code: first three digits → 077
Look up 077 → Dialog
Local: 077 123 4567 · International: +94 77 123 4567

Input

+94 72 123 4567

Normalise: strip spaces → +94721234567
Country code: +94 → leading 0 → 0721234567
Validate: 10 digits, starts with 07 → valid mobile
Operator code: 072 → Hutch (previously Etisalat)
Local: 072 123 4567 · International: +94 72 123 4567

Input

0791234567

Normalise: already 10 digits → 0791234567
Validate: matches ^07\d{8}$ → passes the shape test
Operator code: 079
Look up 079 → not in the TRCSL allocation table
Result: unassigned Sri Lankan mobile prefix — no operator returned

Input

0112345678

Normalise: already 10 digits → 0112345678
Validate: does not match ^07\d{8}$ (starts with 01)
011 is the Colombo landline area code, not a 07X mobile
Result: not a Sri Lankan mobile number
