Vehicle registration plates of East Timor are Australian standard 372 mm × 134 mm, and use Australian stamping dies.

[1] Vehicle registration numbers consist of five digits, and display the letters TL or TLS, short for Timor Lorosae, the name for East Timor in Tetum (or Timor-Leste, the name of the country in Portuguese).

Government vehicles have a similar format, but with four digits and the letter 'G'.

When the country was a Portuguese colony, known as Portuguese Timor, vehicle registrations followed the same format to those used in Portugal, and other colonies, using the prefix T (for Timor) or alternatively TP for Timor Português or Portuguese Timor in Portuguese in white letters on a black background.

As a result, the letters DF were used for registrations in East Timor.
