HTTP Status Code Lookup
HTTP Status Codes
How the status code lookup works
Step 1
Type a code or keyword
Enter a status code such as 404, or a keyword such as "not found" or "server error".
Step 2
Browse matching results
The list filters instantly to show any status codes whose number or name matches your search.
Step 3
Use the reference
Read the code and its standard meaning to help debug an API response, redirect or server error.
Frequently asked questions
Which status codes are included?
The lookup covers the most commonly encountered HTTP status codes across the 2xx, 3xx, 4xx and 5xx ranges, such as 200, 301, 404, 429 and 500.
Does this check the status of a live URL?
No. This is a static reference of what each status code means; it does not send any requests to check a website.
Can I use this offline?
Once the page is loaded, the lookup runs entirely in your browser with no server round-trip needed to search.
