A Finnish number is all the more useful there because Finns readily screen unknown calls from abroad. The application is one of the shortest on the list: a trade register extract and proof of address. For a Finnish company, the extract is the kaupparekisteriote; a foreign company provides the equivalent from its own register. The address makes the difference: it must be within the area code’s zone for a landline, and in Finland for a mobile. A PO box is not accepted in either case. ## Country code and number format - **Local (landline) **: +358 +358, then the area code without the 0 and the number; the length varies. 9 Helsinki, 2 Turku, 3 Tampere, 8 Oulu. Example: +358 9 1234 5678. - **Mobile **: +358 +358 4 or +358 50, then 6 to 8 digits (04x or 050 nationally). Example: +358 45 123 4567. ## What you need to know ### The kaupparekisteriote The extract from the Finnish trade register, issued by the Finnish Patent and Registration Office (PRH). It also gives the Y-tunnus, the Finnish business ID. ### Two official languages Finnish and Swedish are the official languages; English is widely used in business, especially in Helsinki. ### Numbers of variable length As in Germany, Finnish numbers are not all the same length: the area code and the subscriber number vary. ## Call prospects in Finland with a local number Skipcall assigns the local number and your teams call from the browser or the mobile app, with a number your prospects recognise.

The documents are the same. **Is a PO box enough as an address?** No. You need a real address, for a landline as for a mobile.
