The Polish TV content rating system consists of five different tiers, meant to symbolize the minimum age-appropriateness for a TV program.
Green smile face: 0+. This means that content with this rating is suitable for viewing by all age groups. There is nothing unsuitable for children in the program. This does not mean a children's TV program. Equivalent to TV-Y and TV-G.
Yellow 12: 12+. Content with this rating is unsuitable for pre-teenagers. Some coarser swear words than are allowed on 7 may appear, as well as some sexual content. Equivalent to hard TV-PG or soft TV-14.
Orange 16: 16+. Content with this rating is unsuitable for some younger teenagers. Sexual swear words (such as f**k, sh*t, etc.) are allowed, as well as other bad material. This rating can only air from 8 PM until 6 AM. Equivalent to medium or hard TV-14 or soft TV-MA.
Red key 18+. Content with this rating is designed exclusively for adults. This is often used to brand softcore pornography. This rating can only air from 11 PM until 6 AM. Equivalent to hard TV-MA.
