Who to Contact vs Whom to Contact: Which Is Correct? Guide

The difference between who to contact and whom to contact can be confusing because both phrases are used in English, and traditional grammar rules treat who and whom differently.

In modern English, however, who to contact is extremely common and natural, especially in everyday and professional communication. Whom to contact is also grammatically correct and can sound more formal.

Quick Answer

Who to contact is the most natural choice in modern everyday English. Whom to contact is traditionally considered more formally correct because whom is the object of contact. In professional writing, either can work, but who to contact is usually clearer and more conversational.

Why People Confuse It

The confusion comes from the traditional distinction between who and whom:

• Who is traditionally used as a subject.
• Whom is traditionally used as an object.

For example:

• Who contacted you?
• You contacted whom?

In who to contact, however, the phrase is an embedded question:

• I don’t know who to contact.

Traditional grammar would favor whom because the person is the object of contact.

Who to Contact

Who to contact is widely accepted in modern English.

It sounds natural in:

• Everyday conversation
• Emails
• Workplace communication
• Websites
• Customer service messages
• General writing

Examples

• I don’t know who to contact.
• Do you know who to contact about this issue?
• Can you tell me who to contact?
• I’m not sure who to contact for help.
• She asked who to contact about the application.

Whom to Contact

Whom to contact follows the traditional grammatical rule.

Because contact takes a direct object, whom can technically be used.

Examples

• I don’t know whom to contact.
• Please let me know whom to contact.
• She asked whom to contact.
• We need to determine whom to contact.
• He wasn’t sure whom to contact for assistance.

This version sounds more formal or traditional.

When to Use Each

Use who to contact when:

Common Mistakes

A common misconception is that who to contact is grammatically wrong.

It isn’t.

Modern English increasingly uses who in places where traditional grammar would use whom.

For example:

Who to contact ✅
Whom to contact ✅

Both are acceptable.

Memory Trick

Try turning the phrase into a complete question.

Who should I contact?

This sounds much more natural than:

Whom should I contact?

If you’re writing ordinary modern English, who to contact is usually the easiest choice.

American vs British English

Both American and British English use who to contact and whom to contact.

However, whom is generally more formal and is less common in everyday speech in both varieties.

Modern English increasingly favors who, particularly in informal and conversational contexts.
