When there is a word in front of a number that tells what the number is representing, the word is capped with five exceptions: page, line, paragraph, verse, size. The number is always in a figure.
...from Chapter 5...
...is Exhibit 4...
...to Section 15...
...on page 4...
...through line 15...
...to paragraph 3...
If the word number is said, it should be in the form of "No."
...sat is Seat No. 3...
...has License No. 1543...
