Icelandic addresses are short: the street name and house number, then a three-digit postcode before the place name. Names are patronymic, so there is no fixed family surname to match against. Get the postcode or the street format wrong and Pósturinn routes the parcel to the wrong district. Here is the correct structure, a real example, and the mistakes that cause returns.
An Icelandic label is recipient, optional company, the street name with the house number after it, then the three-digit postcode and place name on one line, then the country.
Jón Jónsson Icelandic names are patronymic, not family surnamesDæmi ehf. optional, above the street lineLaugavegur 22 house number comes <strong>after</strong> the street name101 Reykjavík 3-digit postcode first, then the place name, on one lineICELAND required for inbound international shipmentsThe three-digit postcode (póstnúmer) defines the delivery district and drives sorting for Pósturinn. Reykjavík alone spans many codes (101, 105, 107 and more), so the postcode, not the city name, is what narrows delivery.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Every Icelandic postcode is exactly three digits, for example 101. A code padded to four or five digits from another country's habit does not match, and Reykjavík alone uses dozens of separate three-digit codes.
Icelandic addresses write the street then the number: Laugavegur 22, not 22 Laugavegur. Many buildings are identified by street and number rather than a unit, so keep the number attached to the street.
An Icelandic name like Jón Jónsson means Jón, son of Jón; it is not a family surname shared across a household. Do not treat the second name as a fixed last name for matching, and address the label to the full given name.
The three-digit postcode sits before the place name on one line, as in 101 Reykjavík. A form that appends the code after the place reverses the order Pósturinn expects.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.

The national postal operator and the backbone for domestic and inbound mail. Routing is postcode-driven, so a valid three-digit code is the most important field on the label.
Domestic parcel and pickup-point networks for Icelandic ecommerce. They expect the full street and number and a correct three-digit postcode for last-mile accuracy.
International carriers for inbound shipments. Include the country line and keep the accented characters intact; they charge for address corrections on misrouted parcels.
