Other Ways to Say “Who Is This” can help you sound polite and natural when answering an unknown caller or replying to a new contact.
When you receive a phone call, message, unexpected email, or hear from an unknown number, it’s natural to wonder about the person’s identity and look for answers.
The common question, “Who Is This?” is a clear question, but it may sound direct, blunt, abrupt, rude, confrontational, or overly direct depending on the situation, context, tone, and relationship. You can soften the phrase by directly asking in a more polite, friendly, courteous, respectful, natural, and warmer way. “May I know who is this?” is one example that keeps the conversation comfortable. In friendly conversation, casual conversation, texting, or social interaction, especially when speaking with a new contact, thoughtful wording can show respect, warmth, and confidence.
The right wording depends on politeness, precision, naturalness, and how you want to communicate. In a professional setting or business setting, a polished alternative can sound more professional, confident, and appropriate when replying to a phone call, answering client queries, verifying contacts, or handling online inquiries. In my experience, people often respond more comfortably when a question feels thoughtful rather than demanding.
What Does “Who Is This” Mean?
“Who is this?” is a question used to ask for someone’s identity, especially when you do not immediately recognize the person you are speaking to or communicating with. In everyday English, it can mean that you want to know who is calling, messaging, speaking, or contacting you. For example, if an unknown number sends you a message, you might ask, “Who is this?”
The meaning is straightforward, but the tone depends heavily on context. When spoken casually, it can simply show curiosity. However, if said abruptly, it may sound direct or slightly suspicious. In professional or unfamiliar situations, a softer expression can make the conversation feel more respectful.
Common Situations Where “Who Is This” Is Used
People commonly use “Who is this?” during phone calls, text messages, social media conversations, and unexpected personal contact. If someone calls from an unfamiliar number, the phrase can quickly establish who is on the other end. It can also be used when someone contacts you online without introducing themselves.
The phrase is less common as a formal opening in workplace communication because it can sound very direct. In professional settings, a more courteous expression may create a better first impression. The same applies when speaking with a customer, new colleague, teacher, client, or someone you do not know well.
Is It Professional or Polite to Say “Who Is This”?
“Who is this?” is grammatically correct and socially acceptable, but it is generally more direct and conversational than formal. With friends or in casual texting, there is usually nothing unusual about using it. With an unfamiliar person, however, the wording can sometimes sound abrupt, especially if there is no greeting or other polite context.
In professional communication, choosing a softer expression can make the question feel more respectful and approachable. The best wording depends on the situation. A person answering an unexpected business call may want a courteous question, while someone responding to an unknown text may prefer something short and casual.
Advantages and Disadvantages of Saying “Who Is This”
Advantages
The biggest advantage of “Who is this?” is its clarity and simplicity. It immediately tells the other person that you do not recognize them and want to know their identity. It is short, easy to understand, and natural in everyday speech and messaging. It can also be useful when you need an answer quickly.
Disadvantages
The main limitation is its direct tone. Depending on how it is written or spoken, it may sound suspicious, impatient, or less welcoming than intended. It also does not communicate much emotional warmth or formality. In professional or sensitive situations, a more considerate expression may better match the relationship and setting.

Definition
It means “Who is the person speaking to me?”
Detailed Explanation
This is a concise alternative that works especially well over the phone or during voice communication. It is more neutral than “Identify yourself,” but more direct than “May I ask who’s calling?” Because it is short, the tone depends strongly on delivery.

Detailed Explanation
This expression is particularly suited to online conversations, where you may be communicating with someone you have not met before. The word “chatting” makes it sound relaxed and informal. It would feel unusual in a highly formal business letter, but it fits naturally in messaging, social media, and casual online discussions.
Scenario Examples
Scenario: Someone messages you from an unfamiliar social media account.
Example: “Hi! Who am I chatting with?”

It may be appropriate when someone contacts you unexpectedly and you need more information about who they are.
Scenario Examples
Scenario: Someone contacts you without introducing themselves.
Example: “Before we continue, could you tell me who you are?”
Scenario: An unfamiliar person approaches you at an event.

“Who’s there?” asks for the identity of someone whose presence you notice but cannot see or recognize.
Definition
It means “Who is present?” or “Who is at the door or nearby?”
Detailed Explanation
This is not a universal replacement for “Who is this?” because its meaning is more specific. It is normally used when someone is at a door, outside a room, nearby, or otherwise present but unidentified. Using it during a phone conversation would usually sound unnatural because the expression focuses on physical presence.
Scenario Examples
Scenario: Someone knocks on your front door.
Example: “Who’s there?”
Scenario: You hear someone enter another room without knowing who it is.
Example: “I heard someone come in. Who’s there?”

Example: “I’m sorry, who is calling?”

Definition
It means “Who is speaking on the phone?”
Detailed Explanation
This expression is strongly associated with telephone conversations and can sound slightly traditional compared with more modern everyday wording. It is still understandable and can be useful when referring specifically to the person connected to a call. Because it has a somewhat old-fashioned flavor in some settings, it may not be the first choice for casual texting.
Scenario Examples
Scenario: An assistant receives a call for a manager.
Example: “Before I transfer you, may I ask who’s on the line?”
Scenario: You hear a phone ringing while someone else answers it.
Example: “Who’s on the line?”

Definition
It means “Would you mind telling me your name?”
Detailed Explanation
This expression is useful when the main information you need is the person’s name rather than their broader identity. It sounds natural in introductions and everyday professional interactions. Compared with “Who is this?”, it feels less like you are questioning an unknown person and more like you are politely requesting basic information.
Scenario Examples
Scenario: You begin a conversation with someone you have not met.
Example: “I’m sorry, can I ask your name?”
Scenario: A customer approaches a service desk.
Example: “Certainly. Can I ask your name before I look up your appointment?”

14. With Whom Am I Speaking?
Meaning
“With whom am I speaking?” is a formal way to ask for someone’s identity during a conversation.
Definition
It means “Who am I speaking with?”
Detailed Explanation
This is a more formal and traditional construction than most alternatives in this list. It may be appropriate in highly formal communication, although everyday speakers often prefer simpler wording. The expression clearly communicates respect and formality, but it can sound somewhat stiff in casual conversation.
Scenario Examples
Scenario: You are handling a formal business call.
Example: “Good afternoon. With whom am I speaking?”
Scenario: You receive a formal inquiry from an unfamiliar contact.
Example: “Thank you for contacting us. With whom am I speaking?”
Best Use

15. Identify Yourself
Meaning
“Identify yourself” tells someone to state who they are.
Definition
It means “Tell me who you are.”
Detailed Explanation
This is the strongest and most direct expression in the list. Unlike the softer alternatives, it can sound commanding, suspicious, or confrontational, so it should be used carefully.

Scenario Examples
Scenario: An unknown person approaches a restricted workplace area.
Example: “Please identify yourself before entering.”
Scenario: Someone contacts an organization without providing any identifying information.
Example: “Before we discuss the matter, please identify yourself.”
Best Use
