33 of the 192 code points in the Dingbats block are considered emoji.
All of the 80 code points in the Emoticons block are considered emoji.
83 of the 256 code points in the Miscellaneous Symbols block are considered emoji.
637 of the 768 code points in the Miscellaneous Symbols and Pictographs block are considered emoji.
242 of the 256 code points in the Supplemental Symbols and Pictographs block are considered emoji.

Some vendors, most notably Microsoft, Samsung and HTC, add emoji presentation to some other existing Unicode characters or coin their own ZWJ sequences.
Microsoft displayed all Mahjong tiles (U+1F000‥2B, not just U+1F004🀄MAHJONG TILE RED DRAGON) and alternative card suits (U+2661♡WHITE HEART SUIT, U+2662♢WHITE DIAMOND SUIT, U+2664♤WHITE SPADE SUIT, U+2667♧WHITE CLUB SUIT) as emoji. They also supported additional pencils (U+270E✎LOWER RIGHT PENCIL, U+2710✐UPPER RIGHT PENCIL) and a heart-shaped bullet (U+2765❥ROTATED HEAVY BLACK HEART BULLET).
While only U+261D☝WHITE UP POINTING INDEX is officially an emoji, Microsoft and Samsung add the other three directions as well (U+261C☜WHITE LEFT POINTING INDEX, U+261E☞WHITE RIGHT POINTING INDEX, U+261F☟WHITE DOWN POINTING INDEX). Microsoft no longer supports these emojis now.
Both vendors pair the standard checked ballot box emoji U+2611☑BALLOT BOX WITH CHECK with its crossed variant U+2612☒BALLOT BOX WITH X, but only Samsung also has the empty ballot box U+2610☐BALLOT BOX.
Samsung almost completely covers the rest of the Miscellaneous Symbols block (U+2600‥FF) as emoji, which includes Chess pieces, game die faces, some traffic sign as well as genealogical and astronomical symbols for instance.
