HTTP Status Code Reference Generator
Used by developers, writers, and creators worldwide.
An HTTP status code reference generator returns a random status code together with its correct name and a clear explanation of what it means. There are dozens of status codes, and while everyone knows 404, plenty of others — 422, 502, 304 — get confused or misused, leading to APIs that report the wrong thing. This tool pairs each code with an accurate description, drawn from a curated set, so the meaning always matches the number. Choose a class or leave it on any, and generate a code to learn or to look up. It is ideal for learning HTTP, designing APIs, debugging responses, and quizzing yourself. Because every code here is bound to its real meaning, you can trust the pairing while you study. The codes group into families: 2xx success, 3xx redirects, 4xx client errors, and 5xx server errors.

FAQ
what do the status code classes mean
The first digit groups codes into families: 2xx means success, 3xx means redirection, 4xx means a client error like a bad or unauthorised request, and 5xx means a server error. Knowing the family tells you who is at fault at a glance.
are the descriptions accurate
Yes. Each code is paired with a description of what it actually signifies, so the number and its meaning always match. They are written in plain language to be useful for both learning and quick reference while designing an API.
what is the difference between 401 and 403
401 Unauthorized means authentication is missing or has failed — the server does not know who you are. 403 Forbidden means you are authenticated but not allowed to access the resource. In short: 401 is "who are you", 403 is "you may not".
