Manual:Page ID
For user documentation, see Help:Page ID.
A page ID, sometimes article ID (if the page represents an article), is a number that belongs to a wiki page and is unique within the scope of the wiki. It is automatically generated when a page is created and stored in the page_id field of the page table.
General features
[edit]- New page IDs are incrementally generated.
- A page ID is preserved across page moves, making it more reliable and stable as a page identifier than a page title.
- 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.
- It does not identify page revisions, which come with numerical IDs of their own.
- There are various ways users can retrieve a page ID on the wiki. See Help:Page ID.
- If the retrieved page ID is 0, it means the page does not exist.
- Certain service pages that cannot be edited, such as special pages and API pages, do not come with page IDs.
