Sorry for the delay.
You should have received an email regarding your PE license number if you were among a small number who had previously applied through FBPE and took and passed the October 2020 exam.
Most October 2020 exam passers applied directly with NCEES to take the exam. You will not receive a Florida PE number until you have completed and submitted an application with FBPE and paid the fee. (Just remember, you can not apply for your Florida PE license until you have met Florida's requirements, including having the required engineering experience.)
For more information, please see:

Once you have applied and your application is deemed complete and you have completed the Florida Laws and Rules Study Guide (you'll get information about this once you've completed your application), it goes through the Board approval process. If approved, you should receive your PE number in four to six weeks.
