FAA's current wait time to determine if a requested rare or short N-Number is available is 180 to 240 days. Even if the FAA system accepts your N-Number request, more likely than not, the number is unavailable. The Airnautix platform allows you to easily browse a wide selection of available registration numbers and choose the perfect one for your aircraft in just a few clicks. All Airnautix N-Numbers are guaranteed available and ready to transfer.
