How many devices can I have on my Netflix Free Trial?

I read online I could have up to 6 devices on my Netflix account, but Im still on my Free Trial and Im not quite sure if I read it correct but when I was registering for my Free Trial it said I could have up to 3 devices, now from what I read online I could have 6 but I didn't read anything about how many I could have on my Free Trial.. Can I have up to 6 or is the Free Trial only 3 devices.
