I have an app that needs to be downloaded to specific people who have an Iphone. I want to dive them a specific code to download the app. I do not want to have anyone download the app from the app store. I would appreciate any advise
distributing app by coupon
You could look into the enterprise program and distribute it as if you were distributing it only to employees to your company.

And TestFlight.....
>I do not want to have anyone download the app from the app store.
Unless you're talking about testers and ad-hoc, there is nothing anyone here can do in that case. Apple has no authorized 'coupon' redemption scheme, especially one that avoids the store.
Good luck.
