Unknown calls from Germany
Germans tend to be wary of calls from numbers they do not recognise, and with good reason. Advertising calls to private households are only legal with prior consent, yet energy switching offers, lottery promoters and dubious investment pitches still ring through, often with a spoofed caller ID. On top of that come shock calls targeting older people, messenger scams written in casual German, and short ping calls from distant country codes. Expats who have just registered at a new address or signed a mobile contract also receive genuine calls from banks, landlords and authorities, so checking whether an 0800, 0180 or 0151 number belongs to a real business saves a lot of guesswork.
Germany phone numbers at a glance
- Country calling code
- +49
- Trunk prefix
- 0
- Number format
- German numbers have no fixed length. Landlines start with an area code of two to five digits after the 0 (030 Berlin, 089 Munich), followed by the subscriber number; mobiles start with 015, 016 or 017 and usually run to 11 or 12 digits including the 0.
- Example (national)
- 030 12345678
- Example (international)
- +49 30 12345678
- Emergency number
- 112 (fire and ambulance), 110 (police)
- Telecom regulator
- Bundesnetzagentur
To call a German number from abroad, drop the leading 0 and dial +49 first: 030 12345678 becomes +49 30 12345678. A missed call showing +49 at the start came from a Germany number.
How to tell what kind of German number called you

| Mobile (017x) | 017 | 0170 to 0179; the prefix no longer reliably reveals the current network because of number portability. |
