Number format / field size

K

I want to set a Primary key with 16 digits - 4 groups of 4 numbers with
spaces between - which I can use in a calculated field to increment.

I have tried every permutation I can think of, can anyone help please?

Use 4 separate fields, put contraints so that none of them can exceed 9999,
and concatenate them into a single field in a calculated field in a query.
Use the query wherever you would otherwise have used the table.
