The 常用漢字 (Japanese Common Use Kanji) list does not include many kanji that native speakers can read and newspapers don't always follow the rule that they only should use characters from the list. In addition, you need to include the 人名用漢字 (Personal Name Use Kanji) in the list because basically all of those characters are also used in fairly common words.

Native speakers can probably recognise at least 3-4k kanji if not more but can probably only write around 2k from memory, depending on how well-read they are.

嘘 (lie) is the best example of an incredibly common word whose kanji form (which is used fairly often) is not in any official government list.
