0800 Toll-Free Numbers for Switzerland and Germany: Setup and Costs

A toll-free 0800 number lets customers in Switzerland or Germany call your business for free; the company pays for the call, not the caller.

Number allocation is handled by the national regulator in each country (OFCOM/BAKOM in Switzerland, the Bundesnetzagentur in Germany), not by a single incumbent carrier; any licensed telecom provider can operate one.

With a cloud provider like Virtual-Call, international businesses can set up a fully virtual 0800 number without opening a local office or installing hardware.

If your company serves customers in the DACH region but is based elsewhere, a local toll-free number is one of the fastest ways to build trust and remove a real barrier to contact.

This guide explains how the numbers work, why they matter for international companies, and what to expect in terms of setup and cost.

What is a toll-free (0800) number, and who pays for the call?

A toll-free number, prefixed 0800 in both Switzerland and Germany, allows callers to reach a business at no cost to themselves. The company that owns the number covers the cost of the call.

• In Germany, this is a legal requirement for both landline and mobile calls under Section 121 of the Telecommunications Act (TKG). (Bundesnetzagentur, bundesnetzagentur.de)

• In Switzerland, calls from a landline are free, but mobile callers may incur a cost depending on their carrier plan, since Swiss regulation does not mandate free access from mobile networks the way German law does. (BAKOM, bakom.admin.ch)

For most customers, a toll-free number still removes any hesitation about the cost of getting in touch, which is particularly important for support, complaints, or sales inquiries.

Why international companies need a local toll-free number

1. Customer support without a physical presence

Companies expanding into Switzerland or Germany often don't have (and don't need) a local office to offer credible, accessible customer service. A local toll-free number signals that support is available and free, even if your team operates from another country entirely.

2. Market entry and trust-building

A recognizable local number format builds more trust than an international dialing code. For companies entering the DACH market, this small detail often affects whether a prospect is willing to dial the number at all.

3. Centralized multi-country call handling

Businesses serving several European markets can manage multiple toll-free numbers for Switzerland, Germany, and beyond from a single cloud dashboard, with calls routed by language, time zone, or team.

This is especially useful for companies serving Switzerland's multiple language regions (German, French, Italian) from a single platform, without requiring separate local providers for each.

How to set up an 0800 number with Virtual-Call—no local office needed

• Choose a new number or port an existing 0800 number
• Connect it via SIP trunk to your existing phone system, or use Virtual-Call's cloud PBX directly
• Configure call routing by time of day, language, or department
• Go live—accessible to your team from anywhere, with no on-site hardware

Because the entire setup runs in the cloud, your team can adjust routing rules, greetings, or availability at any time, without requiring a technician on-site or a physical presence in Switzerland or Germany.

What determines the cost?

Costs for a toll-free number typically combine a monthly base fee for the number itself and the per-minute cost of calls, which the business,  not the caller, covers.

The exact price depends on expected call volume, the number of simultaneous lines, and any additional features such as IVR menus, call recording, or anti-spoofing protection.

Because usage patterns vary widely between businesses, a tailored quote gives a far more accurate picture than a flat rate.

Switzerland vs. Germany: What's different for 0800 numbers?

The core principle is the same in both countries: the caller pays nothing, and the business covers the full cost. 

The main differences lie in regulation and number allocation—Switzerland's numbering plan is overseen by OFCOM (BAKOM), while Germany's falls under the Bundesnetzagentur, along with differences in carrier pricing structures. 

Virtual-Call provides both national 0800 numbers and international 00800 numbers for Germany, Austria, and Switzerland, so companies serving one or all three markets can manage everything through a single cloud platform, rather than juggling separate local providers for each country.

0800 vs. 00800: What's the difference?

Besides national 0800 numbers, Virtual-Call also offers 00800 numbers—the international standard for toll-free calling.

A national 0800 number only works within one country: a Swiss 0800 number generally cannot be dialed directly from abroad.

A 00800 number, also known as a Universal International Freephone Number (UIFN), was created by the ITU (International Telecommunication Union) specifically to solve this: a single number reachable toll-free in more than 60 participating countries, including both Switzerland and Germany. 

For the caller, the principle stays the same: calls are free in participating countries. For the business, however, international rates apply, typically higher than national tariffs, plus an ITU registration and annual maintenance fee for the UIFN itself.

One important caveat: free access from mobile phones or payphones is not guaranteed in every participating country; it depends on the local carrier.

When does each option make sense?

For a company focused solely on Switzerland or Germany, a national 0800 number is usually sufficient.

For businesses serving customers across several European markets, say, Switzerland, Germany, and Austria, an 00800 number can be the simpler, more brand-consistent choice, since only one number needs to be communicated everywhere.

Frequently asked questions

1. Do I need a local office in Switzerland or Germany to get a toll-free number?

No. A cloud-based provider like Virtual-Call can issue and manage a local 0800 number entirely remotely, with no physical presence required.

2. Who pays for calls to a toll-free 0800 number?

The business that owns the number pays for the call. In Germany, this is a legal guarantee for both landline and mobile calls. In Switzerland, landline calls are always free; mobile calls may involve a cost depending on the caller's own plan, since Swiss law does not mandate free mobile access the way German law does.

3. Can I port my existing toll-free number to Virtual-Call?

In most cases, yes. Porting an existing number is possible without disrupting service or requiring customers to learn a new number.

4. Is a virtual 0800 number reliable for high call volumes, such as a call center?

Yes. Cloud-based toll-free numbers scale with demand and support advanced routing, making them suitable for anything from a small support team to a full call center operation.

5. How is pricing structured for international companies?

Pricing generally includes a monthly base fee plus per-minute call costs, tailored to expected volume. A consultation is the most reliable way to get an accurate quote for your specific use case.

6. What is the difference between 0800 and 00800?

An 0800 number only works within a single country. A 00800 number (UIFN) is international and reachable with the same number in 60+ countries—ideal for companies with customers in several markets, though at higher international rates.
