You can't, without disabling the identity temporarily - and what if you are in a multiuser environment? If two people decide to re-use the old number at the same time, you could be back with teh same problem you are trying to use identity fields to avoid....

If you need a number which reflects a rows position in the number of records, then use the ROW_NUMBER function:

SQL

SELECT Id, Customer, date, Value,
       @@ROWCOUNT as 'Row Count',
       ROW_NUMBER() OVER (ORDER BY Id) AS 'Row Number'
  FROM Customers

That will vary as you insert and remove records, but the identity value can remain safe and unique.
