Region Code

I really hope that someone can help me here?
I live in US and recently purchased the LG TV, year of manufacture is 2015, Model 55UF6800 with WEBOS 2.0.
The default Region code I have now is 22282 (US).
I’d like to change the Region on this TV from US to Russia.
By using Samsung tablet, I was able to get to the Service Menu, where I can change the Region code; however, I don’t know which code is associated with Russia.
I was checking different forums and everyone suggests the 4-digit code for Russia.
All of the Regions on this TV are associated with the 5-digits codes. Can anyone help me with identifying the 5-digit Region code for Russia?
