Decide this rule before importing. It usually makes sense to keep your own verified details and not to treat missing import values as deletion instructions. Test the field mapping with a copy and check your system’s preview.
Export
Before a real import, check how your application handles the export fields. The fictitious sample file helps you test delimiters, accents and text columns. CSV is the standard format; XLSX, JSON and custom columns are agreed before delivery. A direct integration with a particular CRM is not guaranteed.
File structure
Each row is a business, each column a data item. The structure is the same for all industries, so you can combine several exports or import them into the same CRM template.
| Column in the CSV | Label | Content |
|---|---|---|
bedrijfsnaam | Company name | name or trading name as given in the source, including the legal form where it is shown. |
rechtsvorm | Legal form | for example BV/SRL, NV/SA, CV/SC, CommV/SComm, VOF/SNC, vzw/asbl or sole trader, only where the source or the name shows it. |
ondernemingsnummer | Enterprise number | ten digits (0xxx.xxx.xxx or 1xxx.xxx.xxx); the VAT number is BE plus the same number. Empty for now: numbers found on websites are not yet linked to the records. |
straat | Street and number | address of the establishment as given in the source. |
postcode | Postcode | four digits, stored as text. |
gemeente | Municipality | municipality or former municipality (deelgemeente) of the address. |
provincie | Province | one of the 10 provinces or the Brussels-Capital Region, derived from the postcode; the main filter for a regional selection. |
gewest | Region | Flemish Region, Walloon Region or Brussels-Capital Region. |
branche | Industry | one of the 21 basedecontacts.be industries. |
nace_code | NACE-BEL code | economic activity under NACE-BEL 2008, where it can be derived from the source. |
telefoon | Phone | publicly listed business number in international format (+32 …). |
e_mail | publicly listed business address as given in the source or on the website; a data field for CRM and matching, not a consent to advertising. | |
e_mail_type | Email address type | “algemeen” (general: info@, contact@, sales@ …), “persoonlijk” (personal: firstname.lastname@ …) or “freemail”; for a selection under the Royal Decree of 4 April 2003 keep only general addresses of legal entities. |
website | Website | address of the company website including the protocol. |
An empty field means the information was not available in the sources. We never fill it with assumed values. As of 5 November 2026, all records come from Overture Maps, supplemented with contact details from the businesses’ websites: industry and NACE-BEL code are not yet filled in, the legal form only where it appears in the name, and the enterprise number found on websites is not yet linked to the records, so industry, NACE-BEL code and enterprise number are empty for now, and the legal form mostly as well. The quote states which fields your selection contains.
Import guide
postcode, telefoon and ondernemingsnummer in particular as text. Before loading, check a phone number with +32 and an enterprise number with its leading zero.A large file may be of little use for your purpose if a field you need is often missing. Compare the agreed required fields and the confirmed selection size. The database status page explains what the contact figures say and what they leave open.
Preview
The following rows are sample data. The businesses in the table and in the sample file are entirely fictitious so that you can see the structure. Enterprise numbers (with a wrong check digit) and phone numbers are deliberately invalid, and the email addresses end in the reserved domain .example. This is neither a real extract nor a list of contacts to approach.

FAQ
Decide this rule before importing. It usually makes sense to keep your own verified details and not to treat missing import values as deletion instructions. Test the field mapping with a copy and check your system’s preview.
An identical or similar name alone is not enough, especially in Belgium, where many businesses use a Dutch and a French name. Use the address and the website domain; the enterprise number is not yet linked (column empty for now). An establishment unit number identifies a site, not the business. The export does not guarantee a universally complete key.
Do not open the file by double-clicking, otherwise Excel may display accents such as é or ë incorrectly, read phone numbers with a leading plus as a formula and drop the leading zero of an enterprise number.
In an empty workbook choose Data › From Text/CSV, set the file origin to Unicode (UTF-8) and the delimiter to semicolon. Set the postcode, phone and enterprise number columns to text and confirm with Load. LibreOffice Calc opens the import dialogue automatically.
We deliver CSV in UTF-8 with BOM, semicolons as delimiters and CRLF line endings. Excel and LibreOffice recognise this combination reliably. If your application expects commas or tabs, we prepare the file accordingly.
The published figures are as of 5 November 2026: the places come from Overture Maps (release 2026-10-21.0), the additional email addresses and phone numbers from the businesses’ websites, which we are still collecting. We state the data status of your selection with every quote. The date an export is created is not the date each individual contact was checked.
We do not guarantee a fixed update interval for all sources. Details are on the sources and methodology page.
Yes. By default we deliver all 14 columns; on request you receive a file with only the fields you need, for example only records whose email address is of the type “algemeen” (a general address such as info@ or sales@; whether the holder is a legal entity is only shown where the legal form appears in the name). Records without a complete address or without a website can also be excluded.
Only within the exception of the Royal Decree of 4 April 2003: impersonal addresses of legal entities, for products intended for legal entities, with an unsubscribe option in every message. For personal addresses (firstname.lastname@), freemail addresses and sole traders you need prior consent. The column e_mail_type helps you make that selection; it is a technical classification, not legal advice. More: B2B email and the Royal Decree of 2003.
That depends on industry, region and filters. A whole industry in Belgium fits into one Excel worksheet (limit 1,048,576 rows); on request we split very large selections by province or deliver them as JSON.
We state the size after filters, price and data status before you order.
