Timor-Leste IBAN validator

A Timor-Leste IBAN is 23 characters, entirely numeric: “TL”, two check digits, a 3-digit bank code, a 14-digit account number, and 2 national check digits at the end. Unlike several other short all-numeric IBANs covered here — Burundi, Djibouti, and São Tomé and Príncipe all split a separate branch code out from the bank code — Timor-Leste folds branch information into that single 3-digit bank code, going straight from bank identifier to a long 14-digit account number with nothing in between. Timor-Leste is one of Asia’s youngest sovereign nations, having restored its independence in 2002, and its economy runs on the US dollar as official currency rather than a currency of its own — a detail that shapes the banking infrastructure this IBAN format sits on top of. The Central Bank of Timor-Leste (Banco Central de Timor-Leste) oversees the domestic system.

How this validator works

This tool checks the “TL” prefix and confirms all 21 remaining characters are digits, split into a 3-digit bank code, 14-digit account number, and 2 national check digits, then runs the mod-97 checksum (ISO 7064) — entirely in your browser, nothing sent to a server.

What a pass doesn’t tell you

A pass confirms the 23 digits are correctly structured and internally consistent — not that the account is open or belongs to whoever you expect. This tool does no lookup against the Central Bank of Timor-Leste or any commercial bank there. If a Timor-Leste IBAN fails, check the trailing 2 national check digits first, then work backward through the 14-digit account number in groups of four or five.

Scope: Timor-Leste IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Use it to catch a typo before a transfer fails.
