HTTP Status Code Lookup
Look up any HTTP status code and get an accurate description of what it means, organized by 1xx-5xx category.
Search or browse below for any HTTP status code to see an accurate, practical explanation of what it means.
This is a reference lookup, not a live checker - use the Website Status Checker or HTTP Status Checker to see the actual status code a live URL currently returns.
What Are HTTP Status Codes?
An HTTP status code is a three-digit number a server sends back with every response, indicating what happened to the request. The first digit identifies the general category: 1xx informational, 2xx success, 3xx redirection, 4xx client error, and 5xx server error.
Why Use This Tool?
Useful when debugging an API integration or web request and you encounter a status code whose exact meaning you want to confirm - for example, the difference between a 401 and a 403, or a 301 and a 302.
How to Use the HTTP Status Code Lookup
- Type a status code or keyword into the search box, or browse by category (1xx-5xx).
- Select a code to read its description and typical use case.
