How to Find the Swisscom Schweiz AG Address and Contact Details in 2026

Whether you’re mailing a letter, scheduling an in-person visit, or simply need the official address for registration purposes, locating the correct Swisscom Schweiz AG address can feel like hunting for a needle in a haystack. The company’s headquarters and regional offices are spread across Switzerland, and each serves a slightly different purpose. Below, we break down exactly where to find the right address for your needs—from legal correspondence to customer service visits—and how to verify it in real time.

Why the Swisscom Schweiz AG address matters—and when you need it

Swisscom Schweiz AG is Switzerland’s leading telecommunications provider, and its registered office address is often required for contracts, legal notices, or tax filings. The official registered office is in Ittigen, near Bern, but customer service centers and regional branches operate nationwide. If you’re sending a formal letter—such as a complaint, contract termination, or data protection request—using the wrong address can delay processing or even invalidate your communication. Always double-check the recipient’s department and postal code before sending anything.

The official Swisscom Schweiz AG headquarters address

For legal and administrative matters, use the company’s registered office:

Swisscom Schweiz AG
Registered office:
Alte Tiefenaustrasse 6
3050 Ittigen
Switzerland

This address appears on official documents, invoices, and the company’s annual report. If you’re registering a business or filing a formal complaint, this is the address to use. Keep in mind that this location does not handle customer service inquiries—those go through dedicated channels.

Where to find Swisscom customer service addresses by region

Swisscom operates over 100 service points across Switzerland, from Geneva to St. Gallen. These locations handle SIM card activations, device repairs, and in-person support. To find the nearest one, use the official Swisscom locations page and filter by your canton or city. For example:

• Zurich: Swisscom Shop Zurich HB, Bahnhofstrasse 32
• Geneva: Swisscom Store Geneva-Centre, Rue du Rhône 54
• Basel: Swisscom Shop Basel, Steinenvorstadt 68

Each store has specific opening hours, so check ahead if you need assistance outside regular business days.

How to verify the Swisscom Schweiz AG address before sending mail

Mistakes in postal addresses are common, especially with international mail. To avoid errors:

1. Check the Swisscom website: The company updates its registered office and service point addresses annually. Look for the “Contact” or “Company” section.
2. Use the Swiss Post address finder: Enter the company name or postal code on post.ch to confirm the correct format.
3. Call customer service: Dial 1755 from a Swisscom number or +41 800 800 800 from abroad to ask for the exact address of your intended recipient.

What to include in your correspondence to Swisscom Schweiz AG

When sending a letter or package, clarity is key. Always include:

• Your full name and return address
• The recipient’s department (e.g., “Customer Care,” “Legal Team”)
• The correct postal code (e.g., 3050 for Ittigen)
• A clear subject line, such as “Contract Termination – Reference: [Your Account Number]”

If you’re unsure about the department, address your letter to “Swisscom Schweiz AG, Alte Tiefenaustrasse 6, 3050 Ittigen” and it will be routed internally.
