"Arrival at inward office of exchange" is the scan that tells you an international parcel has finally reached your country. It is one of the standard tracking events national posts exchange through the Universal Postal Union, and it appears on international postal tracking, usually after a long quiet stretch that started with "departure from outward office of exchange". People search for it because the words do not say which country the parcel is in, and because the next scan can take a while to appear. This page explains what the arrival scan records, what the "(Inb)" wording means, how it relates to customs, what comes next, and when it is worth asking about.
Short answer: "arrival at inward office of exchange" means your parcel has arrived at the international postal facility in the destination country, your country, after the flight or sea crossing. In the Universal Postal Union's tracking standard this event, code EMD, marks the "End of leg 2 / Start of leg 3": the international journey is over and the in-country part has begun. The inward office of exchange is where mail from abroad is presented to customs, so the next scans are usually customs events or nothing at all until "departure from inward office of exchange". "Item received at office of exchange (Inb)" is the same arrival in different wording, with "Inb" short for inbound. There is nothing you need to do at this status unless customs or the post contacts you.
What "arrival at inward office of exchange" means
An office of exchange is the postal facility where mail passes between one country's post and another's. The outward office of exchange is in the sending country; the inward office of exchange is in the receiving country. The general vocabulary, including transit offices, is on office of exchange meaning.
The Universal Postal Union (UPU), which sets the standards national posts use to exchange tracking data, lists the international tracking events in order. The part that matters here reads:
| UPU event | Wording | Where the UPU places it |
|---|---|---|
| EMC | Departure from outward office of exchange | "End of leg 1 / start of leg 2" |
| EMD | Arrival at inward office of exchange | "End of leg 2 / Start of leg 3" |
| EDA | Held at inward office of exchange | Leg 3 |
| EDB | Item presented to import Customs | Leg 3 |
| EME | Item held by import Customs | Leg 3 |
| EDC | Item returned from import Customs | Leg 3 |
| EMF | Departure from inward office of exchange | Leg 3 |
Leg 1 is the journey inside the sending country, leg 2 is the international transport, and leg 3 is everything in your country up to delivery. So the arrival scan is the hand-over point: the parcel has crossed the border and is now in the hands of your country's post.
Read "inward" as "in my country" and the scan makes sense. It does not mean the parcel is leaving anywhere.
"Item received at office of exchange (Inb)" and other wordings
People search the same event in several forms, because different posts print it differently:
| Wording people search | What it means |
|---|---|
| Arrival at inward office of exchange | The UPU wording of the arrival in your country |
| Item received at office of exchange (Inb) | The same arrival; "Inb" reads as inbound, the receiving side |
| Receive item at office of exchange (Inb) | The same, worded as an action |
| Arrived at processing centre (inward office of exchange) | The same, with the post's own name for the building in front |
| Arrival at office of exchange | The same, with "inward" left out |
| Arrival at outward office of exchange | A different scan: the parcel reached the export facility in the sending country (UPU event EMB) |
No postal operator we could read publishes the "(Inb)" wording with a definition, so the meaning above is the plain reading of the words, matched to the UPU event it sits beside. The "(Otb)" version that some people also see is the outbound side, in the sending country.
Does arrival mean customs has started?
The arrival scan means the parcel is at the place where customs happens. Japan Post's own notice on international tracking, read on 12 November 2026, says that "Mail shipped from abroad undergoes customs clearance procedures at one of the six international exchange offices located in Japan", and that "the customs clearance procedures are under way unless the 'Dispatched from the international exchange office' message appears". Its sample history for a parcel from China shows "Arrival at inward office of exchange" at Tokyo International, then "En route" lines, then "Dispatched from Exchange Office", then "Arrival" and "Final delivery" at the local office.
That pattern holds across posts that follow the UPU events: arrival first, customs while the parcel is at the office of exchange, and a departure scan once it is released. Some posts show each customs step (the UPU's "Item presented to import Customs" and "Item held by import Customs"); many show nothing between the arrival and the departure. The customs stage is explained in awaiting customs clearance meaning.
What comes next after "arrival at inward office of exchange"
- Customs scans, or no scans. "Held at inward office of exchange", "item presented to import customs", or a quiet tracking page.
- Departure from inward office of exchange. The parcel has left the international facility for the domestic network, normally after customs. Explained on departure from inward office of exchange meaning.
- Domestic sorting. In the UPU list, "Item into sorting centre" and "Item out of sorting centre".
- Arrival at delivery office, out for delivery, delivered.
The scan that came before, on the sending side, is explained on departure from outward office of exchange meaning.
How long after "arrival at inward office of exchange" until delivery?
No postal operator publishes a time for this stage, and the UPU's list of events gives none, so this page gives no figure. The time depends mostly on customs, which no tracking page can predict. Japan Post's notice makes the same point from the other side: customs is still under way until the dispatch message appears. Hold the parcel to the estimated delivery date the seller or marketplace gave you.
When "arrival at inward office of exchange" needs attention
- Customs or the post asks you for a payment or documents. Pay or reply only through your post's or customs' official channel. The request will quote the tracking number.
- "Held by import customs" appears. Customs may need information from you or the sender. Contact the sender if you do not know what was declared.
- The seller's estimated delivery date has passed and the arrival is still the last line. Contact the seller, who holds the contract with the sending post and can open an enquiry.
- "Item returned from import customs" or "returned to sender" appears. The parcel is going back. Ask the seller for a refund or a reshipment.
For merchants
The inward office of exchange is where a cross-border parcel goes quiet just as the customer starts to expect it, and the postal wording does not tell them their parcel is already in their country. Pango, an AI-native, agentic operating system for e-commerce logistics, normalises every connected carrier's statuses into one milestone set on a branded tracking page on the merchant's domain, sends proactive notifications including the cross-border handover, and treats a delay as an operational trigger for a proactive message.
The bottom line
"Arrival at inward office of exchange" means your parcel has landed in your country and reached the postal facility that takes in mail from abroad. "Item received at office of exchange (Inb)" says the same thing. The parcel is now waiting for customs, and the scan to look for next is "departure from inward office of exchange". No post publishes how long that takes, so wait for the seller's estimated date, answer customs only through official channels, and contact the seller if the date passes with no new scan. The full vocabulary is on office of exchange meaning.
