Ne question what is an activation code on Netflix?

If I get netflix now, do you have to activate the device first? With a code?

Get new cell phone a few months later. Have read that you have to activate new devices with such a code?

I heard that many didn't get an activation code. When asked to activate the device?

How do you get such a code

You can get it by SMS or email.

OK thanks

You can have it sent by SMS or email. Is a kind of security so that third parties have less chances to do something
