How does package tracking work?

Carriers assign each parcel a unique tracking number that follows a predictable format (length, prefix, check digits). Parcel Tracker Monkey matches that format against known carrier patterns, then links you to the official carrier tracking page where the live status is shown.

Why is my tracking number not updating?

New labels can take a few hours to appear after they are scanned for the first time. International parcels can also go quiet while they move between carriers or clear customs. If a number is still blank after 24–48 hours, double-check it with the sender.

Can I track international parcels?

Yes. Parcel Tracker Monkey supports international formats for USPS, UPS, FedEx, DHL, Canada Post, Royal Mail, Australia Post, and China Post, and falls back to a web search for less common carriers.

Which carriers are supported?

USPS, UPS, FedEx, DHL, Canada Post, Royal Mail, Australia Post, and China Post are detected automatically. You can also pick 'Other' to search for the carrier.

Does Parcel Tracker Monkey store tracking numbers?

No. Recent numbers are kept in your browser's session storage so they survive a page refresh, but they are cleared when you close the tab and never sent to any server.

Can I speed up a customs hold?

Usually only by providing missing documentation if the carrier requests it. Otherwise customs processes on its own schedule.

Why Packages Get Delayed

Weather and network disruption

Storms, floods, and air-traffic disruptions ripple through carrier networks for days. A delayed plane in one hub can push back deliveries across an entire region.

Peak season volume

Black Friday, holiday shipping, and Lunar New Year saturate carriers. Even premium services slow down when volume doubles.

Customs and clearance

International parcels stop at customs for inspection and duty assessment. Missing paperwork or under-declared value can hold a parcel for days or weeks.

Address issues

Typos, missing apartment numbers, and unrecognized formats are a leading cause of failed deliveries. Carriers will usually attempt a correction, but it adds days.

Frequently asked questions

If the tracking hasn't updated in 5–7 business days domestically (or 10–14 days internationally), it's reasonable to ask the sender to open an inquiry.
