Address files

This document describes the contents and formats of the address files.

About the files

This page describes the Swedish address files. What applies to all files, including the postcode files:

  • File name. <article number>_<date>.<extension>, for example se_rec1LKF-W_2026-11-02.csv. The article number is the one on your order: the file's article number plus the delivery frequency (-W weekly, -M monthly, -Q quarterly, -Y yearly, -S single delivery), and on some orders also the format and encoding (se_rec1LKF-W-CSV-UTF8). The date is the delivery date. Change files carry both dates of the period: se_rec4-W_2026-10-26-2026-11-02.csv. If you chose your own file name, it is used instead. Zipped files get .zip added.
  • CSV. Columns are separated by semicolons (;). Values are not quoted. A first row with column names is included if you chose a header row.
  • TXT. Fixed row length: each column starts at the position given in the layout tables. Text is left-aligned and padded with spaces. Start and Length are counted in characters: in UTF-8 files, å, ä and ö take two bytes.
  • Excel. One sheet with the same columns as the CSV file, all cells as text.
  • Encoding. ISO-8859-1 or UTF-8 (without BOM), for CSV and TXT files.
  • Row ending. LF or CR+LF, after every row including the last.
  • Upper or mixed case. In "all caps" files, names (streets, localities, counties and so on) are in upper case. Otherwise they are delivered as in the source.
  • Change files with no changes. When nothing changed during the period, no file is delivered; you get an e-mail saying so instead.

The codes used in the files (address type, range type, address range code) are explained in Column types and Range types.

How the change file works

Each row is a change between the previous delivery and this one. The file compares the address ranges at the start and at the end of the period:

  • Added range: only the New columns are filled.
  • Removed range: only the Old columns are filled.
  • Changed range: both New and Old are filled. A range counts as changed when its address range code changed.

This applies to se_rec4, se_rec4LK and se_rec4LKD. In the TXT file of the change files, street numbers are left-aligned.
