Does international mail require return address

When sending international mail, it's generally recommended to include a return address, but it's not always required. Here's a breakdown:

Required by postal services:

• The Universal Postal Union (UPU) recommends that senders include a return address on international mail items to facilitate return and tracking.
• Some postal services, like the United States Postal Service (USPS), require a return address on international mail items, especially for items sent via airmail.

Recommended by postal services:

• Many postal services, including the USPS, recommend including a return address on international mail items to help ensure delivery and facilitate returns.
• A return address can also help the recipient respond to the sender or return the item if it's undeliverable.

Not required by postal services:

• Some postal services, like the Canadian Postal Service, do not require a return address on international mail items, but it's still recommended to include one.

Best practices:

• Always include a return address on international mail items, especially if you're sending valuable or important items.
• Use a clear and legible address format, including the sender's name, street address, city, state or province, and postal code.
• Consider using a trackable shipping method, like registered mail or a shipping service that provides tracking and insurance.

In summary, while a return address is not always required by postal services, it's highly recommended to include one on international mail items to ensure delivery, facilitate returns, and provide a way for the recipient to respond to the sender.
