Lesotho TIN Format Checker
Check that a Lesotho Taxpayer Identification Number has the RSL format: nine digits, a hyphen and one digit.
What is a Lesotho TIN?
A Lesotho TIN (Taxpayer Identification Number) is the single number Revenue Services Lesotho — formerly the Lesotho Revenue Authority — allocates on registration for income tax, customs and excise, and VAT. The current format is 10 digits written 123456789-0, and a VAT invoice must show both the supplier’s and the buyer’s TIN.
Lesotho TIN format
Nine digits, a hyphen and a final digit.
final digit
Format example: 123456789-0, as used by RSL’s own portal (not a real taxpayer’s TIN).
- Hyphen: Enter the TIN with or without the hyphen; the checker displays it as RSL writes it.
- Older TINs: RSL’s registration form also has a box for older TINs of seven digits, a hyphen and one digit; the checker accepts that layout too.
- Not a TIN: The VAT registration number and the company registration number are different numbers.
- Privacy: Many TINs belong to individuals, such as employees and directors. Never enter another person’s TIN.
How to check a Lesotho TIN

Frequently Asked Questions
What is the format of a Lesotho TIN?
Ten digits, written as nine digits, a hyphen and one digit — for example 123456789-0, the format example Revenue Services Lesotho (RSL) uses. Older TINs used a shorter layout of seven digits, a hyphen and one digit.
Is the Lesotho TIN the same as the VAT number?
No. Every registered taxpayer gets a TIN; only VAT-registered vendors also get a VAT registration number. Both appear on the VAT registration certificate.
Does a Lesotho VAT invoice need the buyer’s TIN?
Yes. A VAT invoice must show the TIN of both the supplier and the recipient. Under the 2026 e-invoicing regulations, sellers in business-to-business and business-to-government sales must also ask for the buyer’s TIN and enter it in their billing system.
Can I look up a Lesotho TIN online?
We found no public TIN search on the RSL website; the RSL portals that take a TIN are logins for the taxpayer’s own account. The checker on this page confirms the format.
Is one TIN used for income tax, VAT and customs?
Yes. RSL allocates only one TIN for income tax, customs and excise, and VAT, and it must be quoted on all correspondence and tax forms.
Does the TIN have a check digit?
The last digit is written after a hyphen, but RSL publishes no check-digit rule, so a format check cannot tell a mistyped digit from a real one.
