A HTTP status code is a three-digit number that states how a request for a given webpage or file was handled. A code may signify that the request worked (e.g. 200) or that it was missing (404) or there was an error (500).

There are a huge number of HTTP status codes, but the first digit of each will tell you whether it was successful or not:

  • 2xx – any code beginning with 2 was successful in some way. The most common response is 200, meaning everything was OK.

  • 3xx – any code beginning with 3 was redirected somewhere else. Common examples include 301 (Moved Permanently) and 302 (Moved Temporarily).

  • 4xx – any code beginning with 4 signifies an error in the request itself, called a “client error”. Common examples include 404 (Not Found) and 403 (Forbidden).

  • 5xx –any code beginning with 5 signifies that an error occurred processing the request, called a “server error”. The most common example is 500, meaning that an unspecified error occurred.
