When you use the compact and repair tool, the Auto Number in a table will be reset to one greater than the largest existing AutoNumber value. For example, consider a table with an AutoNumber field that has 10 rows with autonumbered values from 1 to 10. If you delete rows 6, 9, and 10, and then compact and repair the database, the AutoNumber seed will be reset to 9 (1 greater than the maximum AutoNumber value in the table, which in this example is 8). If the table has no data in it, the AutoNumber will be reset to 1.
Autonumber
Automatically stores a number that is one greater than the last number used. It is used to identify a record by acting as a Primary Key. A Primary Key is unique and cannot be left blank. Even if a number is deleted, that number will never be used again, ensuring that each record can be uniquely identified. You do not have to enter the value. It will automatically enter itself. You also cannot change it.

Autonumber will automatically increment whenever a new record is inserted. The Number data type is just what it says: it's just a number. It doesn't increment automatically. It's just a column that can ONLY take integers that you insert into it.
