Why a targeted list beats a generic database

A sales rep who reaches out to a thousand random companies will close a different number of deals than one who approaches two hundred companies operating in exactly the right industry. Targeting is not a luxury — it is the foundation of efficient B2B sales. The same logic applies to marketing agencies building prospect lists for clients or HR teams looking for partner organisations.

The purpose of targeting is to select records relevant to your business task. Record count alone does not establish data quality or predict response rates. Check which fields are actually available in each segment.

Step 1 – Choose your industry using NACE codes

The European NACE classification – implemented as WZ 2008 in Germany and CZ-NACE in the Czech Republic – divides all economic activity into hundreds of industries. In the Czech Republic, every company in the ARES register carries one or more NACE codes. Selecting the right code is the first filter that separates your target segment from the noise.

  • Section (single letter, e.g. C = Manufacturing) is appropriate for broad awareness campaigns.
  • Three-digit code (e.g. 471 – Retail sale in non-specialised stores) provides medium granularity.
  • Five-digit code gives you the tightest possible segment, for example a specific type of manufacturer.

Tip: If you are unsure of the exact code, browse the NACE tree from the broadest section downward. Most B2B databases offer a full-text search across NACE labels to help you navigate quickly.

Step 2 – Filter by region and company size

A geographic filter is essential for field sales teams, local suppliers, or any campaign where physical proximity matters. Filtering by region keeps the list manageable and ensures you are only chasing reachable prospects.

  • Region: In the Czech Republic there are 14 regions (kraje). You can combine several — for example Jihomoravský and Zlínský to cover Moravia.
  • Company size: A filter on headcount or turnover separates micro-enterprises from mid-market and enterprise targets.
  • Legal form: Limited companies (s.r.o.), joint-stock companies (a.s.), and sole traders (OSVČ) behave differently in a sales conversation and deserve separate cadences.

Step 3 – Layer in VAT status and contact availability

Two criteria that are consistently underused in B2B prospecting can instantly lift your response rates:

  • VAT registration: A VAT-registered company is generally active and has exceeded a minimum turnover threshold. This single filter removes dormant or shell entities from your list. See VAT Payer Reliability in Czechia: What You Must Know.
  • Contact availability: Filter for companies that have a phone number or postal address. Even the most precisely targeted list is useless without a way to reach anyone. Marketing emails require prior consent regardless.

At firmenkontaktdaten.de, we supply a one-off file in response to an enquiry – for Germany via the German company database, for other countries via EU and other countries. Tell us your industry, region and required contact fields; we confirm the available criteria, row count, price and data date before you order. Employee count and turnover are not among the standard export columns.

Step 4 – Order a CSV export and import it into your CRM

Once the selection is agreed, we prepare the export; the export format and sample file page (in German) shows its structure. CSV is compatible with Excel, Google Sheets, and virtually every CRM (HubSpot, Pipedrive, Salesforce). When importing:

  • Map the company registration number (IČO) to your CRM's unique identifier to avoid duplicates on re-imports.
  • Add a campaign tag (e.g. industry=manufacturing; region=JMK; date=2026-08) so you can track segment performance over time.
  • Keep your selection requirements, data date and original file. For a later export, send us the same requirements and agree the new scope and price before ordering.

Step 5 – Keep the list fresh

Czech companies are created and dissolved every day. Contact details change, businesses enter insolvency, and registrations lapse. Working from a year-old list means reaching out to entities that no longer exist or paying for mail that bounces.

Choose when to request a new export based on your use case and the changes you observe. Compare the new and previous files by company ID, separating new entities from changed fields. Preserve your own verified information instead of overwriting it automatically.

Conclusion

A targeted company list built on NACE industry code, region, size, VAT status, and contact availability is the bedrock of any effective B2B acquisition campaign. The tighter the segment, the higher the response rate and the lower the cost per acquired customer. Start narrow, validate your conversion rates, and then expand the list — never the other way around. Industries and coverage: German company database and EU and other countries (both in German).
