Help:Page ID

For developer-oriented information, see Manual:Page ID .

The page ID, sometimes article ID (if the page represents an article), is a number that is unique within the scope of the wiki and identifies a wiki page.

General features edit

  • A page ID is generally more stable, and often shorter, than a page title. Consequently, URLs based on page IDs may be more useful as persistent identifiers than canonical URLs based on page titles. See #How to access a page by page ID below.
  • A page ID does not change when a page is moved.
  • If a page is deleted, its historical page ID persists in the archive table. If the page is restored, it attempts to reclaim its old page ID. This was not yet the case in MediaWiki 1.27 and before.
  • Special pages do not come with page IDs.
