Address errors are the most common cause of delayed and returned parcels — and the easiest to avoid.
An international parcel passes through sorting systems in at least two countries, and each one reads the address differently. The origin hub needs to identify the destination country. The destination's national network needs a postcode it recognises. The final courier needs a street address precise enough to find a door. If any of those three layers is ambiguous, the parcel stalls.
Most address failures are mundane: a missing postcode, a house number written in a position the local system does not expect, a country name written in the sender's language rather than English, or no phone number for a recipient the driver needs to reach. None of these are complicated to get right, but each one reliably costs days.
The full name of the person or the registered company name. For business deliveries, add the contact person on a second line — reception staff need to know who the parcel is for.
Street name and building number. Note that number placement differs by country: it precedes the street name in the UK and Ireland, and follows it in most of continental Europe. Write it the way the destination country writes it.
Put this on its own line. Apartment and floor details buried at the end of a street line are frequently missed, and a parcel that reaches the building but not the door is a failed delivery.
The postcode is the single most important element for automated routing. Use the destination's own format exactly — Portugal uses 0000-000, the Netherlands uses 0000 AA, the UK uses its own alphanumeric structure.
Mandatory for the United States, Canada, Australia, Brazil and India among others. Optional or unused in most of Europe. Omitting it where it is required causes misrouting.
Always the last line, always in English, always alone. 'Deutschland' may not be recognised by an origin sorting system; 'Germany' will be.
Include the country code with a leading plus, for example +351 for Portugal. Many carriers cannot complete a delivery without a working contact number, and mobile numbers work far better than landlines.
Used for delivery notifications and, increasingly, for the recipient to choose a delivery slot or a pickup point. It measurably improves first-attempt delivery rates.
Getting the format right is what lets automated sorting recognise the address.
| Country | Format | Example pattern |
|---|---|---|
| Portugal | Four digits, hyphen, three digits | 1000-001 |
| Spain | Five digits | 28001 |
| France | Five digits | 75001 |
| Germany | Five digits | 10115 |
| Italy | Five digits | 00118 |
| Netherlands | Four digits, space, two letters | 1011 AB |
| United Kingdom | Alphanumeric, two parts | SW1A 1AA |
| United States | Five digits, optionally plus four | 10001 or 10001-1234 |
| Canada | Letter-digit-letter, space, digit-letter-digit | M5H 2N2 |
Business addresses need a contact name as well as a company name. A parcel addressed only to a company arriving at a large building goes to a reception desk that has no idea who to give it to, and often sits there. Adding the department or floor helps further.
Apartment addresses fail most often at the front door rather than at the street. Put the apartment number, floor and buzzer or entry code on their own line rather than trailing them after the street name, where they are easily truncated by address fields or missed by a driver scanning quickly.
Rural and remote addresses sometimes have no meaningful street reference at all. Where that is the case, the phone number stops being a nice-to-have and becomes the mechanism by which the parcel is actually delivered — the driver will call. Adding a short landmark note where the booking form allows it is worth doing.
Finally, some destinations are simply not served by every carrier, and some carry remote-area surcharges. Islands, mountain regions and overseas territories are the usual cases. That is a service availability question rather than an address formatting one, but it surfaces at the same moment — when the postcode is entered.
Omitting the postcode, or writing it in the wrong national format. This is the single most common cause of misrouting.
Writing the country in your own language rather than English on the final line.
Using accented or non-Latin characters. Transliterate into plain Latin script — some systems cannot process anything else.
Burying an apartment or floor number at the end of the street line where it gets truncated.
Leaving out the state or province for the US, Canada, Australia, Brazil or India, where it is required.
Giving a landline instead of a mobile number, so delivery notifications and driver calls never reach the recipient.
Sending to a PO box on a service that requires a physical street address — most express couriers cannot deliver to one.
Copying an address from a message without checking it against an official source.
Ask the recipient to send their address exactly as they would write it locally, then transcribe it without reordering the lines.
Verify the postcode against the destination country's own postal lookup before you book.
Keep the country on its own final line, in English, in capitals if you like — never combined with the city.
Save verified addresses to your account so repeat shipments cannot reintroduce a typo.
For a first shipment to a new address, confirm it by message with the recipient before booking rather than after.
Read the address back character by character on the printed label — it is the last chance to catch an error for free.
Write the street and city as the destination country writes them, using plain Latin characters, and write the country name in English on its own final line. The origin country's sorting system needs to recognise the country; the destination's network needs to recognise everything above it.
Avoid them. Transliterate into plain Latin script — some carrier systems strip or corrupt characters they cannot process, which can turn a valid address into an unreadable one. Plain ASCII is always safe.
It is the most important element of the whole address. Automated sorting routes primarily on postcode, so an incorrect or missing one pushes the parcel into manual handling. Always use the destination's own format.
Rarely on express courier services, which need a physical address and a signature. Postal services generally can. If a PO box is the only option available, check service compatibility before booking rather than after.
Yes, and in international format with the country code. Many carriers will not dispatch a final delivery attempt without a contact number, and for rural or hard-to-find addresses the phone call is often how the delivery actually happens.
