Ms. vs. Mrs.: What's the Difference?
Learn when to use Ms. or Mrs., how the titles differ, how to address someone respectfully, and what to do when marital status is unknown.
Ms. is a marital-status-neutral title for an adult woman. Mrs. traditionally identifies a married woman. When you do not know someone’s preference or marital status, Ms. is generally the safer choice—but a person’s stated preference should always come first.

At 9:05 a.m., an invitation is ready to send, but the contact list shows only “Jordan Lee.” Guessing Mrs. could make an unnecessary assumption; choosing Ms. keeps the greeting professional without adding personal information that was never provided.
Ms. vs. Mrs. at a glance
| Word | Typical role | Meaning | Example |
|---|---|---|---|
| Ms. | Courtesy title | an adult woman, without indicating marital status | Dear Ms. Lee, thank you for your application. |
| Mrs. | Courtesy title | a married woman who uses this title | Mrs. Patel will lead the parent meeting tonight. |
How to use Ms.
Use Ms. when marital status is unknown, irrelevant, or deliberately left unspecified. In American English, it commonly includes a period and is pronounced miz.
Dear Ms. Lee, thank you for your application.
How to use Mrs.
Use Mrs. when you know that the person prefers it. The title traditionally signals marriage, but naming conventions and personal choices vary, so do not infer a preferred title from a surname alone.
Mrs. Patel will lead the parent meeting tonight.
Rules that make the choice easier
Default to Ms. when you are unsure
Ms. does not require you to know or reveal marital status, which makes it practical for business correspondence, applications, and first contact.
Follow the person’s own usage
If an email signature, form, directory, or introduction gives a title, use that choice. Preference is more reliable than assumptions based on age, spouse, or surname.
Keep punctuation consistent with your style
American English usually writes Ms. and Mrs. with periods. British styles often omit them as Ms and Mrs. Either convention can work when applied consistently.
Common mistakes to avoid
- Do not use Mrs. simply because you know that someone is married; confirm that it is the title she uses.
- Avoid addressing an adult professional as Miss unless she has indicated that preference.
- Do not switch between punctuated and unpunctuated titles within the same document without a style reason.
