Mrs\Miss\Ms

When we don't know about years old of woman, Do we have to use Mrs or Miss or Ms?

It's not a question of age, but marital status (Mrs/Miss). Ms can be used for any woman regardless of marital status.

Mrs: for women married
Miss: single
Ms: married or single

Thank you. I'm a beginner.

Women prefer to be known as ( Ms ) rather than Miss "For single" or Mrs "For married"

I always find weird this ms.and mrs. situation as in my mother tongue we don't have that difference we just call "hanım" to every women. So i always call ms. when i am not sure as i don't want to be disrespectful by just assuming, you know.

I also usually call women "miss", especially when dealing with strangers. Because many people are offended when they are called “Mrs.” In college, I write an essay on this subject, because I wonder why this is happening.

I think it is politically incorrect there to address people with Mr, Ms, Miss unless you figure out their genders.
