Overview
DID numbers to Germany
A DID (direct inward dialing) number gives you a real Germany number on your SIP trunk. It receives calls from local customers and, because you hold it, it is also the strongest caller ID you can present on outbound traffic to Germany.
German geographic numbers require a local address in the area code’s region, and we collect that documentation in the portal. 0800 numbers are available without a regional address.
Germany is a high-quality, mostly B2B and customer-care destination. Consumer cold-calling is heavily restricted, so most consumer traffic is service or consented callback traffic.

Dialing & setup
Dialing Germany correctly
- Drop the trunk 0: 030 12345678 becomes +49 30 12345678.
- German numbers have variable length. Never pad, truncate or validate them against a fixed digit count.
- Keep documentation of consumer consent for five years, as UWG §7a has required since October 2021.
- B2B calls need at least presumed consent based on the recipient’s actual interest.
Caller ID best practice
Never suppress the number on promotional calls. Present a German number assigned to you, ideally one that matches your business location.

Quality guidance
What healthy Germany traffic looks like
German routes are high quality. If ASR drops on CLI traffic, check whether the call is being treated as international-origin and the CLI is being suppressed.

Germany DID numbers: FAQ
Can’t find what you need? Our routing team answers within the hour, around the clock.
Can I cold-call consumers in Germany?
Generally no. Promotional calls to consumers require prior express consent, documented and retained. Service calls to existing customers and consented callbacks are the common use cases on our German routes.
Which number should I present?
A German geographic or national number assigned to you. We can supply German DIDs, and the portal lets you authorise them as CLIs in a few minutes.
Why does my German CLI show as unknown?
German networks must suppress German numbers on calls from abroad unless the caller is a roaming mobile customer. Calls routed as international-origin will not display your German CLI.
What consent evidence must I keep?
Under UWG §7a you must document consumer consent to advertising calls at the time it is given and keep that record for five years. The Bundesnetzagentur can request it.
Are B2B cold calls allowed in Germany?
Only with presumed consent, meaning a concrete reason to believe the business is interested. Cold calling a list with no prior connection is risky even in B2B.
What documents do I need for Germany DIDs?
It depends on the number type. Many geographic numbers in Germany require proof of a local address or business registration; toll-free and non-geographic numbers usually need less. The portal lists requirements per number type before you order.
