There are exceptions. I use the AutoNumber field for our IS Request Ticket Numbers. Started it at 1000. (Just so we didn't have ticket 1, 2, etc.). There is no 'real' importance to the ticket number, other then to refer to an exact ticket. Most of the time, we are saying 'That ticket that so and so put in.....'. But if I email Mark about a particular request, I may say Request #xyzm . Where could a problem develop with that? They don't have to be entirely sequential, they have no other meaning then being the identifier for the requests they represent, which is the same purpose they have within the database itself. I have a good reason for changing a starting AutoNumber, however. Just built our online Shopping Cart. It interacts with AuthorizedNet, for credit card purchases. AuthorizedNet requires a number that cannot be repeated from one cart to the next. So, i use the CartID which represents each shopping cart. After testing, I cleaned up the live database, which removed the test carts, and compacted the database. That reset the Autonumber, so I had to bump it back up, into a range which hadn't been used yet, otherwise AuthorizedNet would have refused the transactions.

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.
