If the job posting lists a Bachelor's degree as part of the BASIC qualifications, then you'll almost certainly need one to be considered. There's a lot of HR/Legal crap that goes on behind the scenes with that kind of stuff, but at Amazon where I used to work (and my current, anonymous, company), it's a legal requirement for us to hire someone with a Bachelor's if the job posting has it listed in the basic qualifications. If it's listed in the PREFERRED qualifications section (or not listed at all), then it's not necessary. As far as I know, the degree is the only thing in the basic qualifications that actually legally required if it's listed. Other things like X years of experience in Y technology or whatever aren't legally binding.

Thanks for your response, I’m beginning to get more understanding about it
