About this Tool
Use this free Bitcoin Address Validator to check whether a Bitcoin address is formatted correctly. It can help detect invalid characters, wrong length, unsupported prefixes, malformed Base58 or Bech32 values, and checksum issues where locally supported. The validation runs directly in your browser and does not contact the blockchain, look up balances, or verify every address type cryptographically.
