What is a reference line in business letter?

Answer 1

The reference line on a business letter is a statement describing the main focus of the letter, a number for an account, invoice, etc. or a reference to previous correspondence. Examples:

RE: Request for refund, order number 12345

Ref: Black Arrow refill number XF8910

REF: Case Number JFL4321

The reference line is optional but can be important for the recipient if an account, invoice, claim, proposal, document number of any kind is the subject of the letter.

The reference line is placed between the recipient address block and the Dear..., leaving blank lines between each.

Answer 2

A reference line in a business letter is a key identifier that helps the reader locate specific information related to the correspondence. It typically includes a date, invoice number, order number, or other relevant details to make it easier for both the sender and recipient to track and reference the communication in the future.
