How to get FEI number from FDA?

Could you please elaborate on the process of obtaining an FEI number from the FDA? I understand that FEI stands for Facility Establishment Identifier, but I'm unsure of the specific steps involved in acquiring one. Is there a form that needs to be filled out? Are there any fees associated with the application? Additionally, how long does the process typically take, and what happens if my application is denied? I'd appreciate any guidance you can provide on this matter.
