Sequential Order Numbers

How Order Numbers Are Stored
It’s important to know why all of these IDs are out of order in the first place. WordPress saves everything as a post. Pages are posts, media files are posts, products are posts, orders are posts and posts are posts. This makes it really easy for SearchBar Marketing to interact with the database since everything uses a similar format. All the posts (media, pages, posts, etc) use the same database table and because of that they can’t share the same ID.
