Description

firmenliste.net gives you live access to B2B company address data for Germany, Austria, and Switzerland — about 12.5 million records across 6,400+ industry lists, maintained by Adresskontor GmbH, a German address publisher with 20+ years in the business. Ask in plain language and get real numbers, not estimates: how many dental practices in Bavaria have an email address, what a list of freight forwarders in Hamburg costs, or how many pharmacies are within 50 km of a postcode. Every answer comes live from the same systems that power our shop. What you can do: - Search 6,400+ industry lists by keyword and compare size, field coverage (email, phone, website, contact person), and price - Get exact record counts and prices for complete lists, email-only packages, per-state packages, and postcode-radius selections (1–200 km) - Look up the machine-readable purchase and usage terms before you buy The app is purely informational and read-only. It never sells anything and never completes a purchase: ordering, payment and delivery happen exclusively on firmenliste.net. Data there is delivered as CSV/XLSX download after payment. Prices are net, plus German VAT. B2B only.
