The parts with a name here are: Bank code, account number, national check digits. The bank decides the bank code and the account number; you never have to work them out yourself. The layout code TL2!n3!n14!n2!n is how the registry writes this: a number, then n for digits, a for capital letters or c for letters or digits.

How to check an IBAN of Timor-Leste

  1. Count the characters without spaces. There must be exactly 23.
  2. The first two must be TL, and the next two must be digits.
  3. After those four, the rest must follow the layout: 3 digits, then 14 digits, then 2 digits.
  4. Run the check-digit test. The IBAN checker does all four steps for you and shows which one fails.

Writing it down

On paper, an IBAN is written in groups of four characters with spaces, as in the example above, so that it is easier to read and compare. In online banking and in files it is entered without spaces. Both forms are the same IBAN. Letters are always capitals.

How it compares

At 23 characters, it sits between the shortest IBAN in the registry (Norway, 15 characters) and the longest (Russia, 33 characters). The same length is used by Gibraltar, Iraq, Israel, Oman, Somalia, United Arab Emirates, each with its own layout. After the country code it has digits only.
