HTTP status codes are three-digit responses from web servers that indicate whether a specific HTTP request has been successfully completed. Our HTTP status code checker provides a comprehensive reference with search functionality to help developers quickly understand server responses.

What are HTTP Status Codes?

HTTP status codes are standardized codes sent by web servers in response to client requests. They are grouped into five classes based on the first digit, indicating the type of response.

Status Code Categories

• 1xx Informational: Request received, continuing process
• 2xx Success: Request successfully received, understood, and accepted
• 3xx Redirection: Further action needed to complete the request
• 4xx Client Error: Request contains bad syntax or cannot be fulfilled
• 5xx Server Error: Server failed to fulfill an apparently valid request

Common Status Codes

The most frequently encountered status codes include 200 (OK), 301 (Moved Permanently), 302 (Found), 400 (Bad Request), 401 (Unauthorized), 403 (Forbidden), 404 (Not Found), 500 (Internal Server Error), and 503 (Service Unavailable).
