How to Send International Mail
What may you mail to other countries? Anything that may not be sent within the United States may not be sent internationally. Many countries have additional prohibitions to obey.
Make sure that you’re using standard sizes for your envelopes and boxes. If your mail item can’t fit through automated processing equipment, it is considered nonmachinable and costs more to send.
Write or print your return address and the address you’re mailing to clearly in the correct spots to make sure your mail is delivered on time.
International shipments can be sent via Global Express Guaranteed®, Priority Mail Express International®, Priority Mail International®, First-Class Mail International®, First-Class Package International Service®
You are required to fill out a customs form when shipping internationally, except when sending non-negotiable documents or correspondence weighing under 16 oz via First-Class Mail International.
Correct postage helps your packages arrive on time. Shipping costs depend on several factors. You can enter your package information into the USPS Postage Calculator to get international postage prices for different services.
Where to mail your box depends on its size and how you’re paying for postage. You can drop small packages in a blue collection box, visit your local Post Office™ location, or request free package pickups on certain items.
