Yes, "To Whom It May Concern" is capitalized.
In formal letters and professional correspondence, this salutation follows title case rules, where major words like pronouns, verbs, and nouns are capitalized.

Capitalization Rules

The standard format capitalizes the first letters of "To," "Whom," "It," "May," and "Concern."

  • "To" starts the phrase, so it's always uppercase as the first word.
  • "Whom," "It," "May," and "Concern" get capitals because they are key content words in salutations, per style guides like Chicago Manual of Style.

This differs from sentence case, where only the initial word would be capitalized ("To whom it may concern").

Why It Matters

Proper capitalization signals professionalism and attention to detail in business letters, job applications, or references.
Using all lowercase can appear sloppy and reduce the document's credibility.

Example in a letter:

To Whom It May Concern:
I am writing to inquire about...

Style Guide Variations

  • Chicago/APA: Full title case for salutations ("To Whom It May Concern").
  • Modern alternatives: Some guides suggest lowercase for non-personalized emails, but traditional use sticks to capitals.
  • Forum views (e.g., Reddit discussions) often echo this, stressing formality.

When to Use It

Reserve for unknown recipients in formal contexts like recommendation letters or complaints.
Avoid if possible—personalized names (e.g., "Dear Ms. Smith") build better connections.

TL;DR: Capitalize as "To Whom It May Concern" for formal writing to maintain polish.
