Sri Lanka Phone Number Checker and Formatter - +94, 07X and Area Codes

Sri Lanka's numbering plan, published by the Telecommunications Regulatory Commission (TRC), uses 10-digit national numbers that start with the trunk prefix 0. Dialled from abroad, the 0 is dropped and +94 is put in front, so there are nine digits after +94. Mobile numbers are in the 07 range. A landline number is a three-digit area code beginning with 0, such as 011 for Colombo, then a seven-digit subscriber number.

The checker strips spaces, hyphens, dots and brackets, then reads the number as local (0...), international (+94... or 0094...) or international without the plus sign (94...). A 0 written after +94, as in +94 (0) 71 234 5678, is dropped. Nine digits with no leading 0 are read as a local number that lost its 0. Seven digits alone are refused, because the area code is missing.

A landline number is valid only if its area code is in the TRC table, which is shown below. The plan's text mentions 33 local areas but its table lists 29 codes, and this tool uses the table. The area name is the town the table gives for that code; a code can serve nearby places too, so treat it as a guide. An unlisted code is reported as not recognised, which can mean a typing mistake or a newer allocation. Special-service numbers such as short codes and freephone numbers are not checked.

The tool does not name the company behind a mobile number. The plan reserves the whole 07 range for mobile services and does not tie a prefix to a company. The regulator has been preparing mobile number portability, which lets people keep a number when they change company. A prefix is therefore not proof of who runs a number. The check is also about shape only: a valid result does not mean the number is in service.
