2024.12 Update

How are you?

Port 1Z is a UPS self-certified port, so it's not an internal customs clearance.

Previously, when you logged in to the UPS homepage, a reference number that could be traced in your country was displayed, but now it is not displayed in this way, so you can request access and notification through the number on the email or text message sent when the item crosses into your country.

Thank you.

=====================

How are you?

It's an 18-digit UPS number that starts with 1Z.

There's a separate reference number, so the registration process is a bit cumbersome.

First of all, you need to sign up for UPS.

Sign up

After signing up.Logged in and searching shipping container.And when you do that, you get a screen like this.

In the lower right area of the shipment details, you'll see that the first line in the section called "Reference Number (s) " is the number used in your country.

You can use that number to view your transit status and get alerts.

You can also use that number in the Customs' Unipass to enter B/L.

Thank you.
