Regex Editor & Tester

Validates Chilean vehicle license plates (patentes) line by line, supporting both the newer four-letter + two-digit format (e.g., ABCD-12, ABCD12) and the older two-letter + four-digit format (e.g., AB-1234, AB12-34). Hyphens between segments are optional in every position, so plates with or without separators match. Commonly used for form validation, toll systems, and transport data parsing.
