Zefix, local.ch, Google Maps: Choosing the Right Source for Your B2B Leads in Switzerland

If you're looking to expand your B2B network in Switzerland, you know how crucial accurate and up-to-date business data is. Often, the first step is to turn to public sources, and among the most well-known are Zefix, local.ch, and Google Maps. But not all sources are created equal, and choosing the wrong one can cost you precious hours and yield incomplete or incorrect information.

This guide will help you understand the specifics of each platform, so you can choose the best one for your lead generation needs, saving time and increasing the effectiveness of your campaigns.

Zefix: The Official Registry for Maximum Legal Reliability

Zefix (Central Business Name Index) is the official and centralized database of the Swiss commercial registries. It is the most authoritative and legally binding source for information on companies registered in Switzerland. If you are looking for data that must be legally unimpeachable, Zefix is the starting point.

What you'll find on Zefix:

• Exact company name: The officially registered corporate name.
• Registered office: The official address of the company.
• UID number (Company Identification Number): This is the unique and fundamental code for every company in Switzerland. It is the equivalent of a VAT number in other countries, but with broader functions. It is crucial for invoicing, business relationships, and tax compliance.
• Legal status: Active company, in liquidation, bankrupt, etc.
• Commercial register extract: Access (often for a fee for the full extract) to details on founders, board members, company purpose, share capital, and historical changes.
• Legal form: For example, AG (Aktiengesellschaft / Public Limited Company), GmbH (Gesellschaft mit beschränkter Haftung / Limited Liability Company), sole proprietorship.

When to use Zefix:

• To verify the legal validity and existence of a company before entering into an important partnership or business relationship.
• To obtain a company's UID number, essential for invoicing and compliance.
• When you need information on board members or founders for high-level contact or due diligence purposes.
• To ensure the registered office address is correct for official correspondence.

Limitations of Zefix:

• Lack of direct contact details: Zefix rarely provides phone numbers, specific email addresses, or websites.
• Less intuitive user interface: Searching can be a bit cumbersome and is not designed for mass lead generation.
• Costs: The full commercial register extract is paid.

local.ch: The Swiss Business Directory for Specific Contacts

local.ch is the largest and best-known online telephone directory and business directory in Switzerland. It is the ideal source if you are looking for direct contact details and practical business information for companies.

What you'll find on local.ch:

• Phone numbers: Often both the general number and, in some cases, numbers for branches or departments.
• Physical addresses: Not only the registered office, but also various operational branches.
• Email addresses: Many companies publish them on their local.ch profile.
• Websites: Direct links to company websites.
• Opening hours: Useful for commercial activities or services.
• Service/product descriptions: Companies often upload a brief presentation of their business.
• Industry sectors: Useful categorization for filtering leads.
• Reviews and ratings: Customer feedback (if available).

When to use local.ch:

• To obtain phone numbers and email addresses for your telemarketing or email marketing campaigns.
• To find addresses of specific branches or stores in a given geographical area.
• To identify companies in a ** specific sector** (e.g., restaurants in Zurich, marketing agencies in Geneva).
• When you need information on services offered to personalize your business approach.

Limitations of local.ch:

• Not an official legal source: Information is self-declared by companies and may not be updated as promptly as Zefix in case of legal changes (e.g., bankruptcies).
• Voluntary presence: Companies can choose not to list themselves or not to provide all data.
• Asterisk in the phone directory: Some companies may have an asterisk, indicating they do not wish to be contacted for commercial purposes. Ignoring this may lead to violations of the Unfair Competition Act (UWG) or the new Data Protection Act (nLPD/revDSG).

Google Maps: The Source for Location and Local Visibility

Google Maps is a global mapping platform that also includes a vast database of commercial businesses. It is excellent for location-based searches and for visualizing a company's physical presence.

What you'll find on Google Maps:

• Precise geographical location: Ideal for viewing businesses on a map and calculating distances.
• Basic contact information: Address, phone, website (if provided by the company or extracted by Google).
• Opening hours: Updated by the owners themselves or the community.
• Reviews and ratings: Extremely important for local reputation.
• Photos: Images of the exterior and interior of the business.
• Directions: Primary function of Google Maps.

When to use Google Maps:

• To identify businesses in a specific geographical area (e.g., all hairdressers in a Basel neighborhood).
• When physical location is a key factor (e.g., installers, local suppliers, shops).
• To get a visual overview of the distribution of businesses in an area.
• To check the reputation and reviews of a potential lead.

Limitations of Google Maps:

• Variability of accuracy: Data is often entered by users or business owners, and its completeness and timeliness can vary.
• Lack of legal or structural data: You will hardly find the UID number or details about the board of directors.
• Duplicates and outdated listings: It is not uncommon to find closed businesses or outdated listings.
• Difficult mass extraction: It is not designed to download lead lists in a structured way.
