tried to reply but your PM box is full. Not sure why they'd need a tax id number to replicate an FO, but you should be able to give then your EIN or FEIN number you aquired with the IRS when you applied for your business license. If you haveen't already done that, you can request just an EIN. Try that. If that doesn't work. You might be out of luck. Just out of curiousity, which manufacturer did you go to and what minimum did you have to purchase in order to have your fragrance replicated?
