In letter writing: Re: is an abbreviation for "regarding" or "in reference to." It is used to introduce the subject or topic* of the letter. Example: Re: Your application for the scholarship. Ref: is an abbreviation for "reference." It is used to cite a specific reference number*, file number, or a previous communication that the letter relates to. Example: Ref: Our meeting on 15/03/2024 (File No. ABC-123). The main difference is that Re states the general subject, while Ref provides a specific identifier for a particular document or interaction.
