Importing address registries

Last updated: 17 June 2026

In this article

In the address fields in Opter – for example, in the order reception module and on the customer web – you can get address suggestions when you enter a postcode, for instance. In order to obtain such suggestions, address information needs to be imported. Several different address information files can be imported, for example for different countries.

To keep your address information up to date, we recommend that you import the address information files at regular intervals. If a street cannot be found in Opter, it is probably because the address registry is out of date.

Addresses manually entered by users in order reception and in the web portals are saved in a temporary address registry and are also displayed as suggestions in the address fields. These addresses are not deleted when a new address information file is imported.

It can take a long time, up to 50 hours, to import new addresses because the address information files are often very large.

Step 1: Download the address information file that is to be imported

The address files can be in different formats and look different for different countries.

The data provider in Denmark has changed the format of its address files, and it is not currently possible to import them into Opter. Further information is available at File extract (DAR).

If Estonian addresses are required, download the file sihtnumbrid.zip from geoportaal.maaamet.ee (click on “Postal codes” under “Free download” on the right). The file contains address data in the CSV format with postcodes and is updated once a month, so we recommend that it is downloaded and imported at regular intervals to keep the address information up to date.

If Finnish addresses are required, download the latest base address file, BAF_<yyyymmdd>.zip, from Posti’s website. The file is updated weekly, so we recommend that it is downloaded and imported at regular intervals to keep the address information up to date. For more information, see https://www.posti.fi/en/customer-support/postal-code-services.

If you want Latvian addresses, download the file aw_eka.csv from data.gov.lv (click the down arrow next to the ‘Download’ button and select CSV). The file contains address data in the CSV format with postcodes. It is updated regularly, so we recommend that you download and import it from time to time to ensure you have the latest address details.

When imported, the Latvian letters ā, ē, ī, ū, ō, ķ, ļ, ņ, ģ and ŗ are replaced by the corresponding ‘standard’ letters, without diacritical marks: a, e, i, u, o, k, l, n, g and r.

Norwegian address registries can be purchased from Postnummerservice and Bring.

Further information about the address register from Postnummerservice, along with sample files, is available at www.postnummerservice.se/sv/datafiler. You can order the file here. Download the file in CSV format. We recommend that you select the ‘UTF8’ character encoding.

For more information about Bring’s Gateregister, see https://www.bring.no/tjenester/adressetjenester/adresseregistre (in Norwegian). It is also possible to download a postcode registry from Bring free of charge as a tab-separated TXT file, but it only contains postcodes and towns/cities, not full addresses. For more information about this file, see https://www.bring.no/tjenester/adressetjenester/postnummer (in Norwegian).

Both the suppliers’ files are updated regularly, so we recommend that they are downloaded and imported at regular intervals to keep the address information up to date.

If you would like Swedish addresses, you can purchase the “Address File” from Postnummerservice, item number rec1. Further information and sample files are available at www.postnummerservice.se/sv/datafiler. You can order the file here. Download the file in CSV format. We recommend that you select the ‘UTF8’ character encoding.

The file is updated regularly, so we recommend that it is downloaded and imported at regular intervals to keep the address information up to date.

Step 3: Import the address information file

Click on Alusta in the Aadressi import window to start the import. A preview opens. If the address rows appear to be correct, click on Import. Opter checks the format of the file, deletes existing addresses for the country in question (addresses entered in order reception and the web portals, and the temporary address registry, are not deleted) and then imports the new addresses.

The status of the import is displayed in the Aadressi import window. When the import has finished, the window can be closed.
