Question

What is used to provide page number and date information

Answer 1

The "Number" data type is used to provide page number.

The "Date and Time" data type is used to provide date.

Answer 2

your document already has a text header or footer (such as a running head or chapter name) and you want to add page numbers, you'll need to use Quick Parts tool with field codes. If you try to add page numbers to an existing header or footer by using Insert > Page Number, your existing text will be replaced by page numbers.

If you're not using a text header or footer, go to Add page numbers to learn how to quickly add page numbers to your document.

Note: If you're using your browser to edit a document in Word Online, see Add page numbers to headers or footers in Word Online, later in this article.
