One thing you may hear a lot in Korea is the expression "주시기 발압니다." especially at the end of announcements and official statements. That's a very polite way of saying, "Please know this information."
So, as others have said, 주시다 is the most polite form. However, from my understanding, "give" is a receiving action in Korean for the most part. If you want to "give" someone something (let's say "help"), then you would say:
도와 드릴까요? Can I help you?
도와 주세요. Please help me.
