USPS International Tracking

Need to track a USPS package going abroad? If your item was sent using an international USPS service with tracking, you can follow its progress from the U.S. to its destination. Enter the tracking number on USPS.com or Ship24 to get updates like export scans, customs clearance, and final delivery status.

USPS International Services That Include Tracking

The following USPS international shipping options come with tracking:

• Priority Mail International (6–10 business days)
• Priority Mail Express International (3–5 business days)
• Global Express Guaranteed (1–3 business days)
• First-Class Package International Service (7–21 business days)

These services let you see when your package leaves the U.S., passes customs, and arrives in the destination country. Tracking may pause during customs checks or when handed off to a local carrier.

How to Track International Mail with Ship24

To check your USPS international tracking on Ship24:

1. Visit the USPS tracking page.
2. Enter your USPS tracking number.
3. View all available scans from USPS, customs, and international partners in one place.

Ship24 pulls tracking data from multiple sources, helping you stay updated even when packages are transferred to another courier overseas.

Why International Tracking May Pause

It’s common for tracking to stop for a few days during customs clearance or while the package moves between facilities. In most cases, it resumes after clearing customs or once scanned by the destination carrier.

• Customs inspections can cause delays without updating the tracking info.
• Some international partners may not scan every movement of your item.
• Ship24 may show extra scans not available on USPS.com if the local courier reports them.

Estimated Delivery Times

Actual delivery times depend on destination country, customs processing, and local courier handling.

Common International Tracking Statuses

Informed Delivery and International Packages

Informed Delivery mostly shows letter-size domestic mail. It doesn’t display international tracking unless the package also enters the USPS domestic system on return or redelivery. If you're expecting a package from overseas, check the tracking number directly instead of relying on Informed Delivery.

When to Contact USPS

If your tracking hasn’t updated for more than 7 business days, or if the delivery time has passed with no update, you can:

• Contact USPS at 1-800-222-1811
• Use the Missing Mail Request form
• Reach out to Ship24 if you’re tracking a cross-border delivery handled by another courier

FAQs About USPS International Tracking

Which USPS international services include tracking?

Tracking is available with Priority Mail International, Priority Mail Express International, Global Express Guaranteed, and First-Class Package International. Letters and postcards don’t include tracking.

Why has my USPS international tracking stopped updating?

This can happen during customs inspection or while waiting for a scan by a local courier. It’s often temporary and resumes once the package clears or reaches its next checkpoint.

Can I track a USPS international package on Ship24?

Yes. Ship24 shows tracking details from USPS and other international carriers. It’s helpful if your item switches couriers once it leaves the U.S.

What does “Processed Through ISC” mean?

This means your package was scanned at an international service center and is preparing to leave the U.S. It usually travels to the destination country next.

What should I do if my package is stuck in customs?

Wait a few days for customs to complete processing. If the delay continues beyond a week, contact USPS with your tracking number or submit a Missing Mail request online.
