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

When writing an email, filling out a form, or asking for the right person to reach, you may wonder whether to say “who to contact” or “whom to contact.” Both expressions appear in English, but they follow different grammatical patterns. The confusion comes from the traditional distinction between who as a subject pronoun and whom as an object pronoun.

In everyday English, however, the choice is not always as strict as grammar textbooks suggest. “Who to contact” is extremely common and sounds natural in modern conversation and general writing. “Whom to contact” is grammatically traditional and can sound more formal. Understanding how these pronouns work will help you choose the right expression for emails, professional communication, academic writing, and casual conversations.

Quick Answer

Both “who to contact” and “whom to contact” can be correct. “Who to contact” is more natural and common in everyday English, while “whom to contact” follows traditional object-pronoun grammar and is more formal. In most situations, “who to contact” is the safest natural choice.

Why People Confuse It

The confusion comes from the difference between who and whom.

Traditionally:

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

For example:

• Who called you?
• You called whom?

In “who to contact,” the word who is connected to the verb contact. Since contact takes an object, traditional grammar would favor “whom to contact.”

However, modern English increasingly uses who where traditional grammar would expect whom.

That is why both forms can be encountered in real-world English.

First Word: Who

Who is traditionally a subject pronoun.

It refers to the person performing an action.

Examples

• Who sent the email?
• Who is responsible for this project?
• Who should I call?
• Do you know who manages the office?

In modern English, who is also frequently used in places where traditional grammar would use whom.

That is especially common in speech and informal writing.

“Who to contact”

The phrase “who to contact” means “which person you should contact.”

For example:

I don’t know who to contact about my application.

This sentence is natural and widely used.

Second Word: Whom

Whom is traditionally the object form of who.

It is used when the person is receiving an action or following a preposition.

Examples

• Whom did you contact?
• Whom should I invite?
• To whom should I send the letter?
• Whom are you looking for?

Therefore, from a traditional grammatical perspective:

I don’t know whom to contact.

is the more formal construction.

“Whom to contact”

“Whom to contact” means exactly the same thing as “who to contact.”

The main difference is formality and grammatical tradition, not meaning.

When to Use Each

Use “Who to Contact” in Everyday English

Choose “who to contact” when you want your English to sound natural and straightforward.

It works well in:

• Conversations
• Emails
• Text messages
• Customer-service questions
• General websites
• Workplace communication
• Informal writing

Example:

Could you tell me who to contact about the problem?

This sounds completely natural to most modern English speakers.

Use “Whom to Contact” in Formal Writing

“Whom to contact” may be appropriate when the context is particularly formal.

It can appear in:

• Formal correspondence
• Academic writing
• Official documents
• Legal or institutional communication
• Traditional formal English

Example:

Please advise me whom to contact regarding the application.

The sentence sounds more formal and traditional.

A Useful Alternative

If you are uncomfortable choosing between who and whom, rewrite the sentence:

Could you tell me the appropriate person to contact?

This avoids the issue completely.

Examples: Who to Contact vs. Whom to Contact

1. I don’t know who to contact about my order.
   Natural and common.
2. I don’t know whom to contact about my order.
   Formal and traditionally grammatical.
3. Can you tell me who to contact?
   Very natural in conversation.
4. Can you tell me whom to contact?
   More formal.
5. Please let me know who to contact for assistance.
6. Please let me know whom to contact for assistance.
7. Do you know who to contact about the complaint?
8. Do you know whom to contact about the complaint?
9. I’m not sure who to contact at the university.
10. I’m not sure whom to contact at the university.
11. Could you tell me who to contact regarding my application?
12. Could you tell me whom to contact regarding my application?
13. We need to determine who to contact first.
14. We need to determine whom to contact first.
15. She asked me who to contact for technical support.

In all of these examples, the basic meaning remains the same.

Common Mistakes

1. Assuming “Whom” Is Always Better

Some learners believe that whom is automatically more correct or more sophisticated.

That’s not necessarily true.

Modern English commonly uses who in situations where traditional grammar prescribes whom.

2. Thinking “Who to Contact” Is Always Wrong

This is another common misconception.

“Who to contact” is a well-established expression in modern English.

For ordinary communication, it is often the more natural choice.

3. Confusing “Who” With “Whose”

Remember:

• Who = person
• Whom = object form of who
• Whose = possession

Examples:

Who called?

Whom did you call?

Whose phone is this?

4. Using “Whom” Without Understanding the Sentence

Using whom simply to make writing sound formal can sometimes make a sentence feel unnecessarily stiff.

Always consider the context and your audience.

Memory Trick

Use the he/him test.

If you could replace the word with he, use who.

If you could replace it with him, traditional grammar favors whom.

Example

Who called you?

Replace who with he:

He called you.

So who is correct.

Now:

Whom did you call?

Replace whom with him:

You called him.

So whom is traditionally correct.

For:

I don’t know whom to contact.

Think:

I should contact him.

Therefore, traditional grammar favors whom.

But in everyday modern English:

I don’t know who to contact.

is also extremely common and natural.

American vs. British English

Both American and British English use who and whom, but everyday usage has changed considerably in both varieties.

In informal speech, who is increasingly preferred over whom, particularly in questions and constructions where whom would traditionally be expected.

Whom remains more common in formal, careful, or institutional writing.

Examples:

• Who should I contact? — natural and conversational
• Whom should I contact? — formal or traditional
• To whom should I address the letter? — highly formal

The distinction is therefore more strongly associated with register and formality than with a simple American-versus-British divide.

The difference is mainly grammatical tradition and level of formality. “Whom to contact” follows the traditional object-pronoun rule, while “who to contact” reflects common modern English usage.

For everyday conversations, emails, and most general writing, “who to contact” is natural and widely accepted. For highly formal writing, “whom to contact” may better match a traditional formal style.

FAQs

Yes. “Who to contact” is widely used in modern English and is natural in everyday communication.

Is “whom to contact” correct?

Yes. “Whom to contact” follows the traditional grammatical distinction between subject who and object whom.

Which is more formal: who or whom?

Whom is generally perceived as more formal or traditional, especially when it functions as an object.

Should I say “who should I contact” or “whom should I contact”?

Both are used. “Who should I contact?” is more natural in ordinary modern English, while “Whom should I contact?” has a more formal or traditional tone.

Is “who to contact” better for an email?

For most ordinary professional emails, “who to contact” sounds natural and clear. If the email is highly formal, “whom to contact” is also possible.

Why is “whom” used before “to”?

In traditional grammar, whom is used because the person is the object of the verb contact.

I need to contact him.

Therefore:

I need to know whom to contact.

Can I avoid using who or whom?

Yes. You can rewrite the sentence:

Please tell me the appropriate person to contact.

This is clear and avoids the who/whom distinction entirely.

Conclusion

The choice between “who to contact” and “whom to contact” can seem complicated because traditional grammar and modern English do not always follow exactly the same patterns. Traditional grammar treats whom as the object form, making “whom to contact” the formal construction. Modern English, however, frequently uses who in the same position.

For everyday English, “who to contact” is a natural and widely understood expression. “Whom to contact” remains useful when you want a more formal or traditional tone, particularly in official or academic contexts.

Remember This

Who to contact = natural, modern, and commonly used.
Whom to contact = traditional, formal, and grammatically object-based.

A simple rule to remember is:

Who → he
Whom → him
