Learn everything about the TRON address format. A valid TRX address always starts with 'T', is exactly 34 characters, and uses Base58Check encoding for security.
Understanding the TRON address format is essential for anyone sending, receiving, or verifying transactions on the TRON network. An incorrectly formatted address will be rejected by wallets and explorers, protecting users from costly mistakes.
Every TRON wallet address shares the same structure: it begins with the capital letter "T", followed by 33 alphanumeric characters, for a total length of 34 characters. TRON uses Base58Check encoding, which is a format also used by Bitcoin and designed to minimize transcription errors by avoiding easily confused characters.
Base58Check encoding deliberately omits four characters that can be visually ambiguous: the number "0" (zero), the uppercase letter "O", the uppercase letter "I", and the lowercase letter "l". This means a valid TRON address will never contain any of these characters.
A valid TRON address looks like: TQn9Y2khEsLJW1ChVWFMSMeRDow5KKAXY. The famous USDT-TRC20 contract address is: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t. Notice that both begin with "T" and are exactly 34 characters long.
TRON mainnet addresses always start with "T". TRON testnet addresses follow the same format but operate on a separate network with test tokens that have no real value. Always verify you are on the correct network before sending real assets.
The leading "T" is a result of TRON's specific address prefix (0x41) combined with Base58Check encoding. This prefix is hardcoded into the TRON protocol and distinguishes TRON mainnet addresses from addresses on other networks.
