Where should be a receiver's address on either left or right?

In a formal letter, the receiver's address should typically be placed on the left side of the page, just above the date. This format is standard in most letter styles, including block and modified block formats. However, if using a more creative or informal style, the address could be placed on the right side, but this is less common. Always ensure that the address is clear and easy to read, regardless of its placement.
