Depends on if you want a *true* number, or a text number.

For Text, precede the entry with an apostrophe ( ' ),
OR, pre-format the cell as text.

For true numbers, custom format the cell with the number of digits you're
using:

00000

How do you make the first number in a string of numbers a zero and keep it
there?
