Lambert, <<An AutoNumber field is supposed to uniquely identify a specific row in a table. That's all.>> I was just about to mention that, but you beat me to it<g>. The minute someone says they want to start at a specific value, you have to question why they are using an autonumber at all. Much better to assign your own keys if you need that.

An AutoNumber field is supposed to uniquely identify a specific row in a table. That's all. The user's need not ever see or know the value of such an AutoNumber field, it's used by the database to link related tables together. If the value of an AutoNumber field is important to a user then it is being given some other meaning, and that's only going to cause problems down the line. In effect you are storing two pieces of information in one field, and that's contrary to the normalization principals we should all at least be aware of. Even Microsoft seem to have woken up to this as A2K+ no longer reset AutoNumber's on compacting (thanks for testing that John). Just my 2 cents.
