Whole number? Floating point? Negatives?

If you can cope with a whoe number or fixed point number, consider using a
field of type Decimal, with the Precision property set to 16.

You don't seem to be really talking about a "Number" field.
For instance, in the Table Design view of a table if you choose type
"Number", then the largest integer type available (shown in the bottom
section) is Long Integer which has the range
-2147483648..214 7483647. That is, less than 16 digits.

You probably want a "Text" field, of maximum length 16 characters.
Set up a text field with Field Size 16, and an Input Mask of
999999999999999 9 so that users can only enter digits
