Canada
canadapost-postescanada.ca is where a postal-leg number continues once it is inside Canada. A UPS or FedEx courier number stays on ups.com or the FedEx tracker instead — both carriers deliver door to door on this lane.
International tracking
How to track an international parcel
A tracking number issued in the US does not automatically work on the destination country's own postal site, and it does not need to when a courier carried the box. What decides it is whether the label came from a courier running one network across the border, or from a postal service that hands the parcel to a foreign post partway through. SMKlog sells self-service international labels on four lanes — Canada, the United Kingdom, Germany and Australia — and every carrier and delivery-days figure below came from that live checkout on 2026-09-01.

One number, sometimes two networks
A courier number stays on the courier's own site. A postal number can change hands at the border.
What actually crosses the border on SMKlog's four lanes
The same 0.6 kg test box, quoted to a representative address in each country on 2026-09-01, returns a different mix of carriers depending on the destination — and that mix is what decides which site a customer ends up checking.
| Lane | Carriers returned | Fastest delivery estimate | Slowest delivery estimate |
|---|---|---|---|
| US to Canada | UPS, FedEx, USPS | 2 business days | 8 business days |
| US to United Kingdom | UPS, FedEx | 2 business days | 8 business days |
| US to Germany | FedEx, DHL Express, USPS | 2 business days | 7 business days |
| US to Australia | UPS, DHL Express, USPS | 3 business days | 8 business days |
Germany is the one lane with no UPS option on this account, confirmed twice now at two different test weights on two different dates. USPS's own export rate showed up on three of the four lanes in this test — it did not appear at all on the United Kingdom lane, and it was absent from every lane in an earlier capture at a heavier test weight. Whether a USPS-coded rate returns is not a fixed yes or no for a given country; it moves with the parcel's own weight and dimensions.
One network or two: why it matters for tracking
UPS, FedEx and DHL Express each sell an international product that stays inside their own worldwide operation from pickup to the recipient's door — no other company's barcode reader ever touches the box. That is the entire idea of a courier account, and it is why a UPS or FedEx or DHL Express number typed into that same carrier's own site keeps working the whole way, exactly like a domestic shipment.
A USPS-coded rate works differently by design. International mail moves under a treaty system between national postal operators, so a USPS number is only guaranteed to read on usps.com for the US leg; once the parcel is handed to the destination country's post for the final leg, that country's own tracking system is what carries the rest of the story. USPS's own page on its First-Class Package International Service does not promise full delivery tracking everywhere it ships:
“Get Electronic USPS Delivery Confirmation® International (E-USPS DELCON INTL®) when you ship online to select destinations, although certain limitations may apply.”
USPS, First-Class Package International Service, usps.com, read 2026-09-01.
“Select destinations” and “certain limitations” is USPS's own way of saying delivery confirmation is not uniform across every country it mails to. A courier account does not carry that same caveat, because the courier's barcode reader is the only one that ever scans the box.
The portal for each destination
United Kingdom
royalmail.com/track-your-item covers a postal-leg parcel once it lands. This lane's live courier options are UPS and FedEx only — no DHL Express or USPS-coded rate returned on it in this test.
Germany
No separate portal applies on this lane's courier rates. FedEx and DHL Express are the only couriers this account returns for Germany, and both carry the box on their own network the whole way — the number on the label is the only number needed, checked on fedex.com or dhl.com.
Australia
auspost.com.au/mypost/track/search is the stop for a postal-leg number. UPS and DHL Express are this lane's courier options, both tracked on their own sites the entire trip.
A label bought through SMKlog's own checkout carries the same number into our own tracking page, which reads the issuing carrier's status directly — worth checking first regardless of which of the four lanes or which carrier a specific order used.
Reading a quiet page correctly
A hold at customs is not a lost parcel
Inspection is a physical stop, not a scanning event, so a tracking page can show nothing new for a day or more while the box sits in a customs queue and nothing has actually gone wrong.
No stated window means no baseline
USPS's export rate returned without a delivery-days figure on every lane it appeared on in this test. Without a printed window, there is no number to measure a quiet stretch against in the first place.
A handoff can cost a day on its own
Moving from one operator's system to another's is itself a step, separate from customs, and it is common for the destination country's tracking page to lag a day behind the US carrier's last scan while that transfer completes.
Wrong site, not wrong number
Pasting a courier number into a postal site (or the reverse) returns nothing, and it is easy to mistake that for a lost number rather than the wrong tracking system.
Where these facts come from
- SMKlog's own checkout, live quotes for a 0.6 kg box, 30 × 20 × 10 cm, from Berkeley Heights, NJ 07922, to Canada, the United Kingdom, Germany and Australia — every carrier, service and delivery-days figure in the table above. Captured 2026-09-01.
- USPS, First-Class Package International Service — the delivery-confirmation eligibility quote above. Read 2026-09-01.
- Canada Post, Track a package; Royal Mail, Track your item; Australia Post, Track your parcels — the three destination tracking portals linked above, confirmed live on 2026-09-01.
fedex.com's own tracking pages returned an access-denied response on every attempt on 2026-09-01, so no FedEx-specific claim on this page is sourced from FedEx directly; the FedEx tracker is linked elsewhere on this site as plain navigation only. Carriers and postal operators revise these pages and their tracking coverage without notice; treat the figures above as what was live on the date shown.
Common questions
How do you track a parcel once it leaves the US?
It depends on which kind of number the label printed. A courier number — UPS, FedEx or DHL Express — stays on that same carrier's own site for the entire trip, because those three run one continuous network across the border rather than passing the parcel to anyone else. A USPS-coded number instead moves into the international postal system, and the destination country's own post is where the later scans show up.
Why does tracking go quiet once a parcel reaches the border?
Customs review is a real, physical stop, and most tracking systems narrate it as a gap rather than a play-by-play. A parcel can sit for inspection with nothing new logged until it clears and starts moving again, which is the single most common reason an on-time international shipment looks stalled on the tracking page.
Does every SMKlog international lane come back with a delivery estimate?
Not always. In a live SMKlog checkout test run 2026-09-01, most UPS, FedEx and DHL Express rates returned a delivery-days figure, from 2 business days on a priority product up to 8 on the slowest economy tier — the lone courier exception was a FedEx economy tier on the Canada lane, which priced with no days figure that run. USPS's own export rate, which appeared on three of the four lanes that same day, never carried a delivery-days figure in the quote at all — a number with no stated window is the hardest one to judge a quiet stretch against, because no window was ever printed on the label.
Which site do I check once a parcel lands in Canada, the UK, Germany or Australia?
Canada Post's own tracking tool for a Canada-bound parcel that finished on a postal leg, Royal Mail's for the UK, and Australia Post's for Australia. Germany is the one lane on this checkout with no UPS option at all — FedEx and DHL Express carry it door to door on their own network, so the same number that printed the label is the number to keep checking.
Can I use a US carrier's tracking number on the destination country's postal site?
Only if a postal product actually carried the parcel. A UPS, FedEx or DHL Express courier number was never handed to a foreign post, so pasting it into Canada Post or Royal Mail returns nothing — that number belongs on the issuing courier's own site for the whole trip, the same as a domestic shipment.
