Using Ms. or Mrs. in a cover letter depends on whether or not you know the marital status of the woman. If you are ever uncertain, it is always safe to use Ms. because it does not make an assumption about her marital status.
Mrs. or Mrs is a commonly used English honorific used for women, usually for those who are married and who do not instead use another title, such as Dr, Professor, President, Dame, Prime Minister, etc. In most Commonwealth countries, a full stop is usually not used with the title. In the United States and Canada a period is usually used. Mrs originated as a contraction of the honorific Mistress, the feminine of Mister, or Master, which was originally applied to both married and unmarried women.
