What you need to know
Peak-season delays happen when parcel volumes grow faster than sorting, transport and last-mile capacity. The important point is to read tracking events in context. A scan describes one moment in a longer logistics process, and the estimated delivery window is usually more useful than a single isolated status.
- Retail promotions and holiday orders create sudden volume spikes.
- Bad weather can interrupt flights, roads and local delivery rounds.
- Customs and security screening add time to international shipments.
- Incomplete addresses and missed delivery attempts cause avoidable delays.
Recommended steps
Check the latest scan, confirm the delivery address and allow one or two working days before contacting the carrier. Start with the tracking history, then verify the order information and keep a record of every message. When another company is involved, note both the original and local tracking numbers.
| Step | What to check | Useful action |
|---|---|---|
| 1 | Retail promotions and holiday orders create sudden volume spikes | Check the official tracking record |
| 2 | Bad weather can interrupt flights, roads and local delivery rounds | Keep documents and screenshots |
| 3 | Customs and security screening add time to international shipments | Contact the responsible carrier or seller |
| 4 | Incomplete addresses and missed delivery attempts cause avoidable delays | Escalate when the promised window passes |
When should you contact the carrier?
Contact the carrier when the promised delivery window has passed, a formal exception appears, the parcel is marked delivered at the wrong place, or the carrier asks for missing information. Routine gaps between scans are common during international line-haul transport, weekends and peak periods.
Before calling, prepare the tracking number, sender and recipient names, delivery postcode, order date and a concise description of the problem. The sender may need to start the formal investigation because the sender purchased the shipping service.
How to reduce the risk next time
Use a complete address, include a reachable telephone number when appropriate, choose a tracked service and keep the order confirmation. For valuable goods, consider signature delivery and insurance that matches the actual value. Never pay unexpected fees through a link in an unsolicited message.

Frequently asked questions
Can tracking updates be delayed?
Yes. Scans may be uploaded in batches, and some transport stages do not generate public events.
Should I contact the carrier or seller first?
For an online purchase, contact the seller or marketplace as well as the carrier. The sender often controls the shipping contract and claim.
Is an estimated delivery date guaranteed?
Usually not unless the chosen service explicitly includes a time guarantee. Customs, weather and address problems can change the date.
Where can I track another parcel?
Open the PostIndex carrier directory and select the company handling your shipment.
