Check one or many response codes against a curated reference covering standard, WebDAV, and frequently encountered statuses.

How to use

  1. Enter three-digit codes separated by spaces, commas, or lines.
  2. Read each official-style reason phrase and explanation.
  3. Use unmatched-code notices for extension or custom statuses.

Common questions
Does this query a live service?

No. It uses a built-in reference table, so results remain available offline.

Why is my code not listed?

Some codes are proprietary, obsolete, or outside the compact reference; the tool labels those as unlisted.
