    • The Registry will send a replacement certificate to the registered owner's mailing address or to another mailing address if requested in writing by the registered owner
  • The registered owner may request a temporary Certificate of Aircraft Registration pending receipt of a replacement certificate
    • The Registry issues a temporary Certificate of Aircraft Registration in the form of a fax that must be carried in the aircraft until receipt of the replacement certificate

UAS Registration:

  • A person operating a civil small unmanned aircraft system (weighing above 0.55 grams) for purposes of flight must comply with the provisions of 91.203(a)(2) of this chapter
  • FAR 91.203(a)(2) states: "An effective U.S. registration certificate issued to its owner or, for operation within the United States, the second copy of the Aircraft registration Application as provided for in 47.31(c), a Certificate of Aircraft registration as provided in part 48, or a registration certification issued under the laws of a foreign country"
  • A UAS registration certificate is therefore required
  • The FAA provides guidance on how to register your drone
  • Nearly all UAS flown in the NAS are required to be registered in the FAA aircraft registration database
  • UAS weighing 55 pounds MGOW or more must be registered under 14 CFR Part 47, Aircraft Registration, detailed above
  • UAS less than 55 pounds may be registered under the FAA's newer 14 CFR Part 48 online system:
  • Part 47 UAS Registration:

    • For those UAS, which do not meet the weight stipulations for registration under 14 CFR Part 48, registration is accomplished under Part 47
      • Additional information on registering UAS under part 47 can be found at:
    • Part 47 registration will result in an "N"-number like those assigned to manned aircraft
  • Part 48 UAS Registration:

    • For most operators of sUAS (those UAS weighing less than 55 pounds MGOW), registration under 14 CFR Part 48, Registration and Marking Requirements for Small UA, will be most expedient and the least expensive
    • 14 CFR Part 48 registrants are those UAS flyers operating under either of the following statutes:
      • Part 107: Under the provisions of Part 107, all UAS must be registered regardless of weight. Operations under Part 107 are generally those involving commerce, but can be for recreation as well
      • Recreational Flyers: UAS that are flown exclusively for recreational purposes must be registered if they weigh 0.55 pounds (250 grams) or more
    • If you are not sure what kind of a drone flyer you are, refer to the FAA's User Identification Tool at:, or visit the FAA Getting Started webpage at:
    • Registrations cannot be transferred between 14 CFR Part 107 UAS and 49 USC 44809 UAS
  • How to Register a UAS Under Part 48:

    • To register a UAS online under Part 48, refer to the FAA's DroneZone website. When registering a UAS online under Part 48, you will need to select registration in either Part 107 or the exception for recreational flyers
    • Registration fees for Part 107 registration are per sUAS, and the registration is valid for three years. Each Part 107 registered sUAS will receive a different number. Recreational flyer registration fees are per UAS and valid for three years, but the same registration number can be applied to any UAS in the registrant's ownership. The recreational flyer will receive one registration number that can be used for all UAS flown by that person. In order to register, a person must be 13 years of age or older and be a U.S. citizen or legal permanent resident. If the owner is less than 13 years of age, another person 13 years of age or older must register the UAS and that person must be a U.S. citizen or legal permanent resident
    • An FAA registration certificate will be issued after UAS registration. The registration certificate (either paper copy or digital copy) must be available for inspection during all flight operations. If an individual other than the registered owner operates a UAS, the registration certificate (either paper copy or digital copy) must also be available for inspection during all flight operations. Federal law requires registered UAS operators, if asked, to show their certificate of registration to any federal, state, or local law enforcement officer. Failure to register a UAS that requires registration may result in regulatory and criminal penalties. The FAA may assess civil penalties up to $27,500. NOTE-The FAA's DroneZone website may be viewed at:
  • Labeling a UAS with a registration number:

    • All UAS requiring registration must be marked with a registration number before being flown. The UAS registration number can be applied to the aircraft by engraving, a permanent label, or written on with a permanent marker
    • Owners must then label all model aircraft with their assigned registration number on the exterior of their aircraft so that the registration can be clearly seen and read from a reasonable distance

Registration Certification Knowledge Quiz:


  • The FAA registration database can be found at
  • The procedures for aircraft registration and issuance of registration numbers are contained in 14 CFR part 47, Aircraft Registration (part 47)
    • Keep in mind however, that registration of an aircraft is NOT a function of airworthiness certification but rather a prerequisite for issuance
    • Rather, the FAA must ensure that an aircraft presented for airworthiness certification is properly registered
  • Specific instructions on how to register an aircraft can be found on the FAA's Aircraft Registry page
  • In the United States, the registration number is often referred to as the N-Number given the letter "N" which precedes the alphanumeric registration identifier
  • Registration (and even accident history) can be found at
  • Definitions for terms discussed here can be found in FAR 47.2, 47.5, and 47.7
  • For information regarding registering aircraft previously registered in the United States, see FAR 47.35
  • As part of modernization, the FAA will transition services such as registration and certification to a web-based system, via the CARES initiative
  • Note also, a change (sale) to the aircraft registration certificate carries special responsibilities if the aircraft is equipped with a 406 MHz ELT
  • Pilots may request specific N-numbers in accordance with FAA guidance
