Germany Phone Number Format: Complete Guide (2026)

Germany Phone Number Format (Quick Overview)

Trying to call Germany but not sure how the number format works? You’re not alone. 

Germany uses different formats for landlines and mobile numbers, and a small mistake can lead to failed calls.

In this guide, you’ll learn the Germany phone number format, how to dial from abroad, and how to avoid common mistakes so your calls connect every time

Germany country code: +49 and how to use it

A country code is the international dialing prefix that identifies a specific nation. Germany’s country code is +49. This is required for all international calls to the Federal Republic of Germany.

Like, when calling from abroad, it’s important to follow the international phone number format. Use your exit code, then 49 (the German country code), then the German number, but drop the leading 0.

For example, a Berlin number, while domestically as 030 XXXX XXXX, becomes +49 30 XXXX XXXX internationally.

And while calling within Germany, keep the leading 0. Dial German phone number 030 XXXX XXXX, no need to add +49 for domestic calls. 

The leading 0 is called the trunk prefix. It signals a long-distance call within Germany. International dialing replaces it with +49, which is why it disappears. 

Germany landline phone number format and area codes

Germany’s landline phone numbers follow a clear domestic structure: 0 + [area code (2–5 digits)] + [national subscriber number].

The leading 0 is the trunk prefix used for dialing within Germany. After that comes the geographic area codes (Vorwahl), which identify the city or region, followed by the local subscriber number.

For international calls, the format changes to: +49 + [area code without the leading 0] + [subscriber number]

Here, +49 is Germany’s country code, and the trunk prefix 0 is dropped.

Overall, a German landline phone number format typically contains 10 to 14 digits (including country code).

The variation in length is intentional: larger cities have shorter area codes, allowing for longer subscriber numbers to accommodate local customers, while smaller towns use longer area codes, leaving fewer digits for individual numbers. This flexible structure ensures efficient distribution of numbers to develop local presence.

Germany mobile phone number format and prefixes

Germany’s mobile numbering plan is straightforward but slightly different from that of landlines. support international roaming, making them essential for international callers and global operations. 

The standard format for Germany cell phones number begins with a mobile prefix and follows this domestic structure: 0 + [mobile prefix] + [subscriber number]. 

All German mobile phone numbers start with the prefixes 015x, 016x, or 017x. The initial 0 is the trunk code used only for domestic dialing. When calling from outside Germany, the format changes to: +49 + [mobile prefix without the leading 0] + [subscriber number]

Here, +49 is Germany’s country code, and the trunk prefix 0 is removed. Most German mobile numbers are 10 to 13 digits long (including country code), depending on the prefix and subscriber number length.

The prefixes are historically linked to specific operators, though this has become less reliable over time. Below is a current overview of major German mobile prefix allocations:

Pro tip: The prefix shows the original network assignment. After number porting, the number may be active on a different carrier. You cannot determine the current network from the prefix alone.  

Germany toll-free, premium, and national numbers

Germany offers several special service numbers types beyond standard landline and mobile formats. These include toll-free, shared-cost, premium-rate services, and non-geographic numbers, each designed for specific use cases.

2. Premium numbers

3. National numbers

A Germany 032 number is not tied to any specific city or region. Unlike traditional area-based numbers, these are nationwide and location-independent.

How to write and format a German phone number correctly

DNI 5008 standard

The DIN 5008 phone number guideline is Germany’s official standard for formatting business documents, including letters, invoices, and email signatures.

For telephone numbers, DIN 5008 recommends a clean, readable structure using spaces only, no brackets or dashes:

Example: +49 30 12345678

Key rules:

• Use +49 for international format
• Remove the trunk prefix 0 from the area code
• Separate groups with spaces only

This format is widely used by German companies, government offices, and formal documents, making it the safest choice for professional communication.

E.164 international format (for systems & APIs)

The E.164 Germany format is the global standard used by telecom systems, CRMs, and APIs. It’s designed for machines, not humans.

Format: +49XXXXXXXXX
Example: +493012345678

Key rules:

• No spaces, no brackets, no dashes
• Always include the country code (+49)
• Remove any leading 0

This is the required format for platforms such as Twilio, Salesforce, and HubSpot, ensuring numbers work correctly across SMS, VoIP, and automation systems.

A valid German number in E.164 format follows these rules:

• Start with +49
• Followed by 9-12 digits (after the country code)
• Mobile: +49 +Mobile Prefix+ 7-8 digits
• Landline: +49+areacode (2-5 digits) + subscriber number

2. APIs, VoIP and Twilio

When using APIs, VoIP platforms, and Twilio, it’s important to format phone numbers in the E.164 standard. This involves removing spaces, brackets, and dashes for a clean format.
