It is used by the Sri Lanka Inland Revenue Department (IRD) to identify taxpayers and their tax liabilities. The TIN number is an essential requirement for individuals and businesses that earn income in Sri Lanka and are subject to taxation.

The TIN number is a 9-digit alphanumeric code that is unique to each taxpayer. The first two digits of the TIN number indicate the region where the taxpayer is registered. The next two digits indicate the type of taxpayer (individual or business), while the last six digits are a sequential number assigned to each taxpayer.
