LetterAgent can't handle military mail: letters to Canadian Forces Post Offices need handling our service doesn't offer. To reach a soldier deployed overseas, address your letter to the member by name, rank, and mission, route it through the Canadian Forces Postal Service using a CFPO address, and drop it at a Canada Post retail outlet instead of a street box.
| Address line | What goes there | Example |
|---|---|---|
| Line 1 | Rank, full name, and mission or unit | Cpl. Jordan Avery, Op UNIFIER |
| Line 2 | CFPO number (the 5000-series number for their location) | CFPO 5002 |
| Line 3 | Belleville ON K0K 3R0 | Belleville ON K0K 3R0 |
The address looks odd because it isn't really a foreign address. Your letter goes to a Canadian military post office that happens to be overseas. Canada Post carries it to a designated base, and the Canadian Forces Postal Service takes over from there, moving it on military sustainment flights to the member's location. That handoff is the whole reason the addressing has to be exact.
Get the details from the member or their family. You need three things: the member's rank and full name, the mission or operation name, and the correct CFPO number for where they are posted. CFPO numbers come from a 5000-series, and each one maps to a specific deployment location. Using last year's number, or a number from a different mission, is one of the most common reasons military mail goes astray.
If the member is serving on a ship, the address uses the ship's name instead of a CFPO number, with an HMCS-style fleet mail address. Either way, the last line stays Belleville, Ontario, with the K0K 3R0 postal code. That Belleville routing is what tells Canada Post this is military mail, not ordinary lettermail to Ontario.
This is the step people skip, and it's the one Canada Post is explicit about. Military mail has to be deposited at a full-service Canada Post retail outlet, not dropped in a street letter box. The counter staff check that you have the right customs forms and the right addressing before the letter enters the system. A letter dropped in a street box with missing or wrong military addressing risks being returned to sender or treated as undeliverable.
There is also a customs angle. Military mail is subject to Canadian customs law and the laws of both the country you're sending from and the country where the member is posted. The retail outlet visit is partly how Canada Post makes sure the paperwork matches the rules before the letter boards a military flight out of Trenton, Ontario.
Letters are the easy case. Parcels are allowed too, but the rules tighten: no dangerous goods, no perishables that won't survive the trip, and nothing that breaks the destination country's import rules. Anything you send should be addressed to a specific individual. Canada Post will not accept mail addressed vaguely to "any soldier" through this channel.
A practical point people miss: keep a copy of anything important. Military mail travels through more hands than a domestic letter, across bases, flights, and sorting points, so anything irreplaceable should stay home. If you need proof something was sent, ask at the retail counter about coverage and signature options, which you can add for a fee.
One of the better deals in Canadian postage: mail to deployed members is priced at domestic rates, even though the letter travels overseas. You pay as though you were mailing within Canada. Delivery takes longer than domestic mail because of the military leg of the journey, so build in extra time and mail early around holidays. Canada Post has run free holiday mailing promotions for troops in past years, but those are seasonal offers, not standing policy, so don't count on them.
