HTTP Status Code Lookup
Quickly look up the meaning of a single HTTP status code.
One code, explained fast
When a request returns a status you do not immediately recognise, you just want to know what it means without scrolling a full list. This looks up a single HTTP status code and tells you its meaning and typical cause, so you can diagnose a response quickly and move on.
Enter a status code and see what it means.
Reading the code's family
The most useful instinct with any status code is to read its first digit, which tells you the category before the specific meaning. A 2xx succeeded, a 3xx redirected, a 4xx means the request was at fault and a 5xx means the server failed — so the family alone points you at whether the problem is in what you sent or on the server side. From there the specific code narrows it down: a 404 for something missing, a 429 for too many requests, a 503 for a server temporarily unavailable. Looking up the exact code confirms the detail.
HTTP Status Code Lookup FAQ
What does the first digit of a status code tell me?
The category: 2xx success, 3xx redirect, 4xx a client-side request problem, 5xx a server failure — which points you at where the fault is.
What is a 429?
Too many requests — you have hit a rate limit and should slow down before retrying.
