Whose vs Who’s: Which One Do You Need?
Whose shows possession. Who’s is who is or who has.
Whose turn is it? Who’s next?
The test that settles it
Expand the apostrophe to who is. If the sentence still works, it is who’s.
“___ bag is this” → who is bag fails, so whose.
“___ calling” → who is calling works, so who’s.
The apostrophe marks a missing letter, never ownership. Possessive pronouns — his, hers, its, theirs, whose — never take one.
Whose: belonging to whom
The possessive form of who, used both in questions and to join clauses. It works for things as well as people.
Whose idea was that?
The writer whose book we read.
A town whose name I forget.
Could you answer with mine or his? Then whose.
Who’s: who is, or who has
A contraction covering two expansions. The apostrophe replaces the missing letters, exactly as in it’s.
Who’s at the door?
Who’s got the tickets?
Tell me who’s coming.
Expand to who is or who has. If either reads, who’s.

The exceptions
Some writers avoid a house whose roof leaks on the grounds that whose should apply only to people. There is no such rule — English has no other single word for the job, and the alternative, of which, is clumsy.
Its and whose are possessives without apostrophes; it’s and who’s are contractions with them. Learning one pair teaches the other.
Where people get it wrong

| a company who’s profits fell | a company whose profits fell | Possession. |
| Whose got the key? | Who’s got the key? | Who has. |

Frequently asked
Why does the possessive have no apostrophe?
Because possessive pronouns never take one. The apostrophe in English marks either a missing letter or a possessive noun — not a possessive pronoun.
Can who’s mean who has?
Yes, when has is an auxiliary: who’s seen it? Not when it means possession — who has a pen? stays uncontracted.
