Yes. In formal writing, you should capitalize it as “To Whom It May Concern:” and usually follow it with a colon.

Quick Scoop

  • The standard, professional form is: To Whom It May Concern:
  • Capitalize the first letter of each main word: To , Whom , It , May , Concern.
  • This mirrors how you’d treat a title or proper salutation line in a business letter.
  • Using lowercase (for example, to whom it may concern) can look informal or careless in job applications or official letters.

Why it’s capitalized

In modern business and professional etiquette, this phrase functions like a formal greeting line, similar to writing someone’s name (for example, “Dear Hiring Manager”). Capitalizing each principal word and placing it on its own line signals formality, respect, and attention to detail, which can affect how seriously your letter is taken.

Recommended format in a letter or email:
