Global communication - international telephone numbers and networking

International numbers

International numbers with coverage in over 80 countries: We offer comprehensive international coverage of local, national and toll-free virtual phone numbers. We currently cover 81 countries and 4625 area codes worldwide, with services provided via private or public VoIP SIP trunks or direct PSTN forwarding.

You can now order international numbers with any tariff. All you need is a direct debit authorization. Numbers can be ordered in the customer center. International numbers are subject to special conditions.

Depending on the application, you can bind the number to a private or public VoIP SIP trunk or use direct PSTN forwarding - as described in the first paragraph. Which variant is right for you depends on your telephony infrastructure and local rules; the desired coverage across countries and area codes remains the common goal.

The direct debit authorization is used for ongoing billing of the booked services; ordering and tracking are carried out via the customer center. Proof of identity and address must be submitted where required by the relevant regulation - not as an additional hurdle, but because number ranges in many countries are linked to such proof.

Important notes

All telephone numbers are subject to the regulatory requirements of the respective country. In certain countries, proof of address in the form of a copy of your personal ID (front and back) and further proof of address in the form of a utility bill (gas/water/electricity or cable TV bill) from the previous month are required. This proof must be provided when ordering.

The minimum contract term for an ordered phone number is 3 months. After this period, all phone numbers ordered can be returned or ported to another provider with 14 days' notice to the end of the month. Additional costs may be incurred by the receiving provider.

Emergency call functionality is not always guaranteed due to the use of phone numbers in the respective country. Use a cell phone or an existing landline in the country for emergency calls.
