HTTP Status Code Lookup

Search the full list of HTTP response codes by number or phrase and read what each one actually means.

How it works

  • Every standard code from 100 to 511 is included, grouped by class (1xx–5xx).
  • Search matches the number, the reason phrase and the description, so “rate limit” finds 429.
  • Each entry lists what the code means and the situation it is meant for.
