A 01 number places you in Vienna, a 0662 in Salzburg. The Austrian application has one particularity: in addition to the registration extract, you need the legal representative’s ID. An identity card, a passport or an identity confirmation issued by a bank are accepted. The address must be within the area code’s zone for a landline, and in Austria for a mobile, with proof to back it up. ## Country code and number format - **Local (landline) **: +43 +43, then the city code without the 0 and the number; the length varies. 1 Vienna, 316 Graz, 662 Salzburg, 512 Innsbruck, 732 Linz. Example: +43 1 234 5678. - **Mobile **: +43 +43 6, then 8 to 10 digits (06xx nationally). Example: +43 664 123 4567. ## What you need to know ### The Firmenbuch The Austrian company register is called the Firmenbuch. Its extract proves the company exists and, if it shows the address, also serves as proof of address. ### Tightly regulated advertising calls Section 174 of the Austrian Telecommunications Act (TKG 2021) prohibits calls for advertising purposes without the subscriber’s prior consent. The law makes no exception for businesses, and the Austrian Economic Chamber (WKO) specifies that the ban also covers first contact with a prospect. ### Vienna and the federal states Vienna has the shortest area code (1). Other cities have a 3- or 4-digit area code, and the number that follows is correspondingly shorter. ## Call prospects in Austria 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.
