Do you love shopping from US stores but get frustrated when they don’t ship to Canada? An international mailbox can be a great solution for you, but how does this service work?
In this blog, you’ll learn everything you need to know about international mailboxes, including how they work, their advantages, and what costs to expect.
Key Takeaways
An international mailbox is a service that provides you with a foreign mailing address so you can manage your mail from abroad.
International mailboxes let Canadian shoppers access US stores that don’t ship to the country and enjoy US-exclusive deals.
Renting an international mailbox is a secure and convenient way to receive and forward packages.
What Is an International Mailbox?
An international mailbox is a service that provides you with a mailing address in another country where you can receive, store, manage or forward mail and packages.
These mailboxes come in different types, including the following:
PO Box. Short for post office boxes, these are secure, lockable mailboxes located inside a post office. They are mailboxes that you rent from postal services like USPS, where you can receive mail securely instead of having it delivered to your address.
Physical Mailbox Services. You can also rent physical mailboxes from private companies like UPS Store. You’ll get a real street address, not a box number. This means you can use the address for online shopping, and your packages can get delivered by other major carriers, not just the postal service. Some also offer additional services like forwarding and holding mail.
Virtual Mailbox Services. These are digital mailboxes where you can manage your mail through an online portal. The company receives your mail, scans its outsides, and uploads images to your account. From there, you can request actions, such as opening and scanning the contents, forwarding items, or shredding documents—giving you full control of your mail remotely.

How International Mailboxes Work
Renting international mailboxes is a convenient way to receive mail and packages abroad. Here’s how they work:
Sign Up for a Mailbox
For PO boxes, you can either apply in person or online. If you wish to apply in person, head over to your preferred post office, like USPS, and do the following:
Fill out PS Form 1093 (USPS’s form for applying for a PO box rental)
Pay all the necessary fees (estimates provided in the latter part of this blog)
Once approved, you can start receiving mail. For more convenience, consider applying online through their website. Search for available boxes at your preferred location, pick your size, and pay the rental fee electronically.
For virtual mailboxes, the process is typically completed online. Sign up, select a street address, and pay the fees online. Private mailbox providers, such as UPS, and virtual mailbox services require you to provide two valid IDs and fill out PS Form 1583. It’s the form that authorizes a Commercial Mail Receiving Agency (CMRA) to receive mail on a customer’s behalf.
Use the Mailbox Address to Receive Mail and Packages
Once you’ve set up your international mailbox, you can start sending all your documents and packages to the US mailing address. The company will notify you via email about the status of your packages.
Manage Your Mailbox
Your mail or package arrives at the mailbox address. Then, you can choose what to do with it:
Arrange for shipment to Canada
Store or hold your mail until you want it shipped
Shred it for security purposes
Send Your Packages to Canada
You can forward your package directly to your Canadian address. Just remember that you’ll be paying for international shipping in addition to the mailbox rental. You can, however, save on shipping costs by consolidating multiple packages into one shipment, so you’ll be paying for one delivery instead of several separate ones.
Additionally, if you’re shopping online, you can use mailbox rental services for US stores that don’t directly ship to Canada. You can ship your items to the mailbox address first, and then forward them to Canada.
Clear Customs and Receive Your Packages
Packages need to clear customs before they can enter Canada. In the customs clearance process, the border services officer may physically inspect items or review your shipping documentation to check if there are any prohibited items.
To avoid customs issues and delays, declare your items accurately and provide the correct item value and description. Once cleared, the package gets delivered to your doorstep just like any other shipment.
Advantages of Using International Mailbox Services
International mailboxes come with many advantages for customers, from flexibility to privacy. Let’s take a look at some of the benefits of using mailbox services:
Access to US Stores and US-Exclusive Deals
When you rent a mailbox, you get a US address you can use to shop from stores that don’t ship to Canada. You can also enjoy US-exclusive deals, letting you save more on your purchases.
Note: Some stores don’t ship to PO boxes. In that case, you can still rent a mailbox from a private company.
Flexibility & Control in Shipping
You have full control over the shipment of your package to Canada. You can choose your carrier and preferred service — whether standard or expedited shipping.
You also get to decide when you want to ship all your items to the country. Mailbox services let you store your packages for weeks for an added fee, so you can wait until you’re ready to consolidate or ship.
Privacy & Security
Instead of giving out your home address to multiple retailers, you can use your mailbox for an added layer of privacy. Your mail or package will be in a secure facility, so there’s a reduced risk of stolen or lost packages.
Just keep in mind, however, that while renting international mailboxes can be useful, they have drawbacks. PO boxes have size limitations, so you might not be able to ship large packages. Physical and virtual mailboxes also have ongoing costs like monthly or annual fees, which can be costly.
How Much Do International Mailboxes Cost?
You’ll have to pay monthly or annual fees to rent an international mailbox.
For PO boxes at USPS, the fees vary depending on the following:
Box size
Duration (3 or 6 months)
Area—whether it’s competitive (within the service area of a competitive mailbox service provider) or market-dominant (not within a nearby competitor)
Fee group USPS assigned the box to—a group with higher or lower rates
Below are the prices for renting a PO box for 3 months in a market-dominant area, under fee group 1 :

Mailbox Rental vs. Package Forwarding Services
Package forwarding services give you a shipping address in another country. They receive packages for you, then forward them to your home address.
Both mailbox rental and package forwarding services can give you access to US stores that don’t ship directly to Canada. But these two have their differences, along with their own set of pros and cons.
Let’s take a closer look at these services and compare them:
Coverage. International mailboxes handle both mail and packages, including personal documents such as letters and bank statements. On the other hand, package forwarding services handle packages only.
Costs. International mailboxes can be more expensive because you have to pay for the mailbox rental plus forwarding costs. Package forwarding services, on the other hand, can be the more cost-effective option because you won’t pay any rental fees. But, take note that some forwarders have registration or membership fees.
Flexibility and Control. Renting an international mailbox gives you more control because you can decide how to handle each item—store packages or choose when and how to forward them. On the other hand, you have less control over package forwarding services, since the company manages the entire shipping process for you.
Convenience. International mailbox services are less convenient because you’re responsible for the shipping, which can take more time and effort. On the other hand, package forwarding services offer more convenience, as they handle both the shipping and customs clearance process on your behalf.

Things to Consider Before Choosing a Shipping Provider
Many shipping providers offer US-to-Canada shipping services. For a smooth cross-border shipping experience, choose a reliable company and consider the following factors:
Shipping Rates & Monthly or Annual Fees. Make sure that their shipping rates align with your budget. Keep in mind that companies require you to create an account to get a US mailing address, and some charge monthly or annual membership fees.
Customs Handling and Other Services. For more convenience, choose a shipping provider that handles the customs clearance on your behalf. You may also want to consider if they have other extra services like package consolidation and storage services for a better shopping and shipping experience.
Storage Time Limits. Ask the company about their storage policies and time limits. This is important because you may want to consolidate packages and decide to hold one first until the other arrives."
Customer Support. Reliable customer service is essential for shipping packages. If issues like delays arise, responsive representatives can quickly help resolve them.
Reviews. A great way to know if the shipping service is reliable is to read the reviews. You can check out Google reviews or websites like Trustpilot. What customers are saying definitely shows if the company’s services are trustworthy.
