Frequently Asked Questions

What do the status code categories mean?

Codes are grouped by first digit: 1xx informational, 2xx success, 3xx redirection, 4xx client errors, and 5xx server errors. The category tells you at a glance who is responsible for the response.

What's the difference between 301 and 302?

301 is a permanent redirect that tells clients and search engines the resource moved for good, while 302 is temporary. Using the right one matters for SEO and caching.

Is HTTP Status Code Lookup free to use?

Yes. HTTP Status Code Lookup is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use HTTP Status Code Lookup?

Absolutely. HTTP Status Code Lookup runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
