When formatting an address on an envelope, which element comes last?

The last element in the formatting of an address on an envelope is the ZIP code. In a standard address format, the sequence typically begins with the recipient's name, followed by the street address, then the city, the state, and finally, the ZIP code. This structure ensures that the address is clear and conforms to postal regulations, facilitating effective mail delivery. The inclusion of the ZIP code at the end is critical because it provides specific geographic information to postal services, allowing for precise delivery routing. By placing it last, it creates a logical flow in the address, making it easier for both the sender and the postal worker to read and understand.
