In the US, the facts in a phone book (names, numbers, addresses) are not copyrightable and neither is the collection. However, see the bit at the end about compilations.
I wonder whether "fake facts" (bogus names, numbers, addresses) are copyrightable. If they are, they can be used to give copyright protection to a collection even when the bulk of the collection isn't copyrightable.
Those fake facts are a thing and have a name [0], they are placed into phonebooks, dictionaries, encyclopedias etc. to detect copyright violations (i.e. somebody else stealing your compilation).

This has, unfortunately, been upheld on occasion. True damages from copying such false entries would be nonexistent, naturally, but statutory damages are blind to such trivialities as justice or proportionality.
Morally speaking, anything presented as fact (including entries in a phone book or notations on a map) should be treated as fact and thus not copyrightable. Something along the lines of estoppel should prevent one from claiming that they are providing a database of facts and then suing the recipient for reproducing copyrightable "creative elements" which don't belong there. Also, selling someone a database of "facts" with deliberate fictitious entries mixed in which are not specifically labeled as such should be classified as fraud and open the publisher up to liability should anyone suffer the slightest harm due to the false entries.
