TIP
If you use only five-digit ZIP codes, the Number data type is fine. But by setting
it to Short Text, you can enter ZIP+4 codes or the letter-number postal codes used in
Canada and some other countries.
Now let's change some of the properties for the PostalCode field.

TIP
Sometimes changing the field properties of a table that already contains data
can produce unanticipated results. If you make a change to a field property that
might cause data to be lost (for example, if you make the Field Size property smaller
than one of the field's existing values), Access warns you of this problem when you
attempt to save the table. For more information, see Chapter 6, “Maintain data
integrity.”
