Hello People, I am having DJI Mavic Air! and for registration of my drone I need Ground Control Station (GCS) Serial Number and  I am not able to find it as for some people they told we can find it DJI Go app in the About Section But I can only find FLight Control Serial number and not able to find FCS!Let me know where can I find that number?

or Is FCS & GCS number are the same number?

I'm facing the same problem...Couldn't find the Ground Control Station (GCS) Serial Number.

GCS SN you will find under remote controller, near the QR code
FCS you will find under the battery on aircraft or on APP

Hi, thank you for your patience. Upon checking here, you can use the SN of your drone to register the drone to any local authorities. Thank you for your support!

Hello, The GCS on the back of my Mavic remote controller has got erased. What do I do to find it again? I couldn't find it in the DJI GO 4 app.
We need it along with the drone SN and FCC SN to register our drones on the government enlistment site.

FCS is the sr no of drone and GCS is the sr no of controller

Hi guys,

You can find the Flight Controller Serial number (FCS) here:
1) inside the drone, where you put the battery, beside the QR code (Air, 2, pro) or just under the battery flap (Mini)
2) on the DJI box of your drone where the S/N is show
3) on the dji go4/dji fly app, on the "about" menu ....Flight controller Serial number (the drone must be connected to the App)

Note: The FCS number is the same serial number you must use for the APR number (if requested)

You can find the Ground Control Station (GCS) here:
1) below the controller itself, beside the QR code

Hope could help

Hello I just activated my new Air2, and I have some problem about GCS code. I had firts get the one under the QR code on the back of the controller and it is 1WPBH5V0020076. Reading the QR code with a QR scanner I had the same result, so I used this one to register my drone to local autorities, but in the Fly App I found a completely different GCS code under Information Menu. It's reported as 396CH5M00405C3. Which one is the correct code?
TY in advance for help

Hi guys,

You can find the Flight Controller Serial number (FCS) here:

On the Digital sky registration platform, white entering the weight of the done, it returns saying invalid input. I entered 0.430 kgs. Why would that happen?

You just need to enter like 0.43

iN mAVIC MINI YOU CAN FIND INSIDE OF BATTERY FLAP OF DRONE

Hi, I have brought DJI Mavic Air before 4 years and need to re-register in another country. I need Pilot or Ground Station Station serial number which is scratched of from the remote control of my drone . What is another way to find Ground control station serial number in the dji app or some other place. I can only see last 5 digits of my serial numbers on the remote controler. Thnaks
