Final answer:
The recipient's address in a block style business letter is referred to as the 'inside address', and it includes the recipient's name, title, company name (if applicable), and their postal address.
Step-by-step explanation:
The address of the person receiving a block style business letter is known as the inside address. This address should be included after the sender's address and date, left-justified on the page. The inside address begins with the recipient's name and title, followed by the company name (if applicable), the street address, city, state, and zip code. For international recipients, the country name should be added. Always follow block formatting rules by keeping the text left-justified and using appropriate business font and size.
Remember that when writing a business letter, the salutation should address the recipient by their preferred title, for respect and formality. For example, addressing as "Dear Dr. Smith" if the recipient holds a PhD.
The recipient's address is a crucial part of a business letter, and neglecting to include it can lead to miscommunication or the letter not reaching its intended destination.
