Curious question on how does international tracking work between eBay and USPS?

[medicatedoil]

Hi everyone,
just a curious question on how the international tracking information between eBay and USPS is integrated?
For example, an uploaded international tracking number on eBay is able to be tracked with all the detailed information. Howevery, the same tracking will prompt a: Not Trackable USPS Tracking® is unavailable for this product for SINGAPORE message on the USPS website.
Even though the package has been handled by USPS as I can see from the tracking results through eBay.

What's your question?

The same international tracking number(s) for packages sent to the USA does not work on the USPS website, but on eBay, they are able to display results.

Below are a few examples:

That doesn't look like a USPS tracking #

Ok I'll try to answer.

eBay has access to many of the various shipping sites. USPS, UPS, FedEx ect. They also have access to many countries online systems.

So they can track an item sent via Singapore post or the UK's mail system.

USPS however may only be able to track an item that either originated in the US or entered our system after being shipped from a foreign system.
However USPS may not recognize the tracking #s from foriegn systems.

They may also upload the tracking to the foriegn system but it won't be trackable in the US system.

That is a registered letter? I don't think USPS tracks international registered mail once it leaves the country but Singapore post must track it so ebay would be getting their info from SP.

The parcel looks like it came from Singapore to the US

Yes, the tracking numbers are for international packages from Singapore to the US.

However, on SingPost website, the item status will be tracked till the point it reachs the US at most.

Kind of strange how eBay is able to provide the full details yet USPS website does not 😕

USPS has stopped tracking for registered items sent from Singapore a few years ago.

Below is a screenshot of the annoucement I managed to dig out:

Can anyone provide the database or site ebay use to provide these extra details?
