For those people in the US, the FAA now requires your FAA registration number to be marked somewhere on the outside of your drone (see more details here). Since the drone is exposed to the elements, it would be best to use some type of marking method that is weatherproof.
To provide you with a better way to mark your drones, I recently added weatherproof FAA registration decals to my store here. These decals are available in various colors and sizes. You can pick the sizes and quantity of each size that’ll work best for you.

These decals come with alcohol pads to ensure a clean install surface, are easy to apply using the included instructions, and will arrive in a strong, rigid paperboard mailer to ensure they aren't damaged during shipping.
Your decals will be created, packaged, and shipped within one business day from the time you place your order. Orders are shipped via USPS first class mail in a strong, rigid paperboard mailer. USPS does not pick up mail on Sunday, so no orders will be shipped on Sundays.
