Regex Tester & Validator

This regular expression is designed to match standard English street addresses. It successfully captures locations starting with numbers or a pound sign (like '123 Main St' or '#4 Oak Ave'), as well as those starting with alphabetic characters (like 'South First St'). The 'gim' flags ensure it performs a global, case-insensitive, and multiline search, making it highly useful for parsing multi-line text documents to extract or validate address lines.
