Market Context and Dataset Foundations
How to reach consumers successfully? If you are a business selling directly to consumers, the challenge has always been the same: who do you target, how do you reach them, and how do you ensure compliance? In this article, we use Belgium as a case example to show how registry-based consumer datasets make it possible to identify the right buyers and connect with them across verified communication channels.
Belgium is often overshadowed by larger European markets, yet it represents a valuable audience for international and domestic brands. High connectivity, strong purchasing power, and cultural diversity make Belgian households attractive targets for campaigns. To succeed here, companies need more than broad digital strategies. They need accurate, compliant consumer data that reflects the nuances of language, region, and household characteristics.
Consumer Market in Belgium
Belgium has a population of 11.7 million people in 2025. More than 95 percent of Belgians use the internet daily, and smartphone penetration exceeds 92 percent. Urbanization is high, with 98 percent of the population living in urban areas. E-commerce is projected to reach €20.1 billion in 2025.
Despite this digital readiness, Belgium is fragmented across language and culture. Reaching Flemish households requires Dutch-first communication, while Walloon households expect French. Brussels is bilingual but leans toward French in consumer-facing materials. East Belgium represents a small but unique German-speaking minority.
These divisions mean that mass campaigns without segmentation risk missing or alienating key audiences. The solution is precise, localized outreach enabled by verified consumer data.
What Is the InfobelPRO Belgian Consumer Dataset?
To overcome these challenges, businesses rely on structured consumer datasets. InfobelPRO’s Belgian consumer dataset is built from registry and opt-in sources, making it both comprehensive and compliant. Unlike scraped lists or inferred profiles, this dataset provides verified contact details and demographic attributes, allowing marketers to target real individuals and households with confidence.
The dataset covers over 5.3 million individual consumer records in Belgium. It includes more than 2.3 million phone numbers, 3.4 million email addresses, and 3.3 million verified postal addresses. Every record is updated, validated, and flagged for consent where required, ensuring GDPR compliance.
What the Dataset Contains
Each record may include:
- First and last name
- Gender
- Date of birth or age range
- Language (Dutch, French, bilingual, German)
- Household income bracket
- Household type (apartment, house, ownership status)
- Postal address (street, house number, postal code, city)
- Geographic coordinates (latitude, longitude)
- Mobile phone (opt-in, DNCM filtered)
- Landline phone (opt-in, DNCM filtered)
- Email address (opt-in, marketing ready)
- Unique InfobelPRO identifier for integration into CRM or campaign systems
This foundation enables companies to build highly segmented audiences that reflect Belgium’s linguistic, cultural, and economic diversity.
Why It Matters
Without registry-based data, businesses often rely on generic targeting through search ads, third-party cookies, or broad demographics. These approaches miss the mark in Belgium because of the country’s fragmentation and strict data regulations. Registry-based datasets offer:
- Verified, consented communication channels.
- Household-level accuracy for direct mail and local campaigns.
- Segmentation by language, income, and household type for cultural alignment.
- Integration into marketing systems through unique IDs for clean CRM enrichment.
In short, the dataset is not just a list of names. It is a structured, compliant resource that allows brands to reach Belgian consumers with precision.
Executing Consumer Outreach with Registry Data
Direct Outreach Channels
Belgian consumers can be engaged through three primary channels: email, phone, and postal mail. Registry-based data ensures that each channel is accurate, consented, and targeted.
Email Campaigns
Email remains one of the strongest outreach tools in Belgium because it combines scalability with compliance. With millions of opt-in records available, companies can:
- Deliver Dutch-language newsletters to Flemish households and French versions to Walloon households.
- Target income groups with differentiated offers, such as premium products for high-income households or discount campaigns for students.
- Launch location-specific promotions based on postal codes, such as a new store opening in Antwerp or Liège.
Belgian consumers expect transparency in email. Clear opt-out options, relevant content, and bilingual subject lines improve trust and performance.
Phone Outreach
Phone remains an important direct channel for service-based industries like telecom, energy, and insurance. The dataset contains millions of opted-in numbers that are filtered against Belgium’s DNCM registry, ensuring compliance.
Applications include:
- Appointment scheduling and service reminders.
- Loyalty campaigns tied to specific postal codes.
- Outbound promotions for local offers, such as gyms or retail centers.
Phone outreach in Belgium must respect language preferences. Using the dataset to match phone numbers with linguistic regions prevents wasted calls and strengthens trust.
Postal Mail and Flyers
Postal campaigns are still powerful in Belgium. Nearly 40 percent of households report engaging with flyers or coupons each month. With 3.3 million verified addresses, marketers can:
- Send bilingual flyers in Brussels neighborhoods.
- Distribute coupons to Walloon households segmented by income.
- Run seasonal promotions to Flemish households, supported by follow-up digital campaigns.
Because addresses are verified and regularly updated, campaigns avoid waste and deliver measurable ROI.

Segmentation for Belgian Campaigns
Registry-based data supports advanced segmentation, making campaigns highly relevant.
Examples include:
- Language segmentation: Dutch campaigns for Flanders, French for Wallonia, bilingual for Brussels.
- Income targeting: Premium products for high-income households, discount promotions for student or lower-income segments.
- Household type: Solar or insurance offers to homeowners, rental promotions to apartment dwellers.
- Geospatial targeting: Address-level selection within 2 kilometers of a store or service point.
Compliance and Trust
Belgium enforces GDPR rigorously. Companies using scraped or third-party data risk penalties and reputational damage. With registry-based data, every record is:
- Verified and updated regularly.
- Opt-in for email and phone campaigns.
- Filtered for DNCM compliance.
Compliance is not just about avoiding fines. It is a trust signal that improves consumer response and strengthens long-term engagement.
Practical Applications
- Retail campaign: A supermarket mails vouchers to households in Brussels, segmented by income, and follows up with bilingual email reminders.
- Telecom outreach: A provider uses DNCM-filtered phone numbers to promote new service packages in Flemish postal codes.
- Hybrid promotion: A retailer distributes flyers to households in Wallonia, then retargets the same addresses with digital ads.
- Energy services: A solar company filters homeowners with specific income levels to deliver targeted offers.
Conclusion
Reaching Belgian consumers requires precision, compliance, and cultural sensitivity. Registry-based datasets provide the foundation by offering verified emails, phone numbers, and postal addresses segmented by region, language, and demographics.
Instead of relying on generic advertising, businesses can use consumer data to design targeted campaigns that resonate locally, protect consumer trust, and deliver measurable results.
