AutoNumber
AutoNumber
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 in Access is a special data type that, starting at 1, automatically adds a number for each line you add... For example... Say you were entering guests that were coming into a hotel. You would write John Smith into the name field, and the autonumber field would automatically add the number 1 to it. The next record would automatically add 2 into the field. So it would look like 1 John Smith 2 Katy Jones This makes it a more efficient way to write lists. The Autonumber field will not let you change the value, even if other records are removed, so ensuring that each record retains its own number.
Automatically stores a number that is one greater than the last number used.
The difference between the greatest and least number is the range.
