Tuvalu
Tuvalu issues a Taxpayer Identification Number (TIN) for tax and business-registration administration, including registered businesses and business taxpayers. Public sources reviewed do not disclose a reliable public validation format or check-digit algorithm.
TIN status
No separate local TIN format is published for validation.
- 1 The TIN appears on Tuvalu business, revenue, and customs registration material and is referenced in consumption-tax rules.
- 2 Publicly reviewed sources support one general TIN rather than separate materially distinct TIN types for business registration, consumption tax, customs, or ASYTIN.
