The UK has one particularity: no supporting document has to be uploaded, for either a landline or a mobile number. The details requested about the company and the person responsible are, however, thorough. The real difference between landline and mobile is the address. For a landline, the company must declare a valid UK address. For a mobile, the address can be anywhere in the world: a company based outside the UK can therefore get a UK mobile number without a London office. The declared responsible person must be a company director in charge of phone numbers. You will be asked for their personal mobile number, on which they can be reached, and which cannot itself be a virtual number. ## Country code and number format - **Local (landline) **: +44 +44, then usually 10 digits. Landlines start with 1 or 2 after the country code: 20 London, 161 Manchester, 121 Birmingham, 131 Edinburgh. Example: +44 20 7946 0123. - **Mobile **: +44 +44 7, then 9 digits (07 nationally). Example: +44 7700 900123. ## What you need to know ### The register: Companies House or equivalent You will be asked for the body that registered the company and its registration number: Companies House for a UK company, or the national business register for a company registered elsewhere (for example the trade and companies register, RCS, in France). ### Silent calls are penalised The UK regulator Ofcom can penalise silent or abandoned calls, typical of auto-dialers set up with too few agents, under its powers against “persistent misuse” of networks. The fine can reach £2 million. ### Mobile or landline? Without a UK address, mobile is the only option. With a local office, a 020 or 0161 landline clearly shows your local presence. ## Call prospects in the UK 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.

You enter the company name, the registration body and registration number, the website, the company address, then the name, mobile number and business email of the director responsible for the numbers. **Can a non-UK company get a UK phone number?** Yes for a mobile, whose address can be anywhere in the world. For a landline, a valid UK address is required. **Why is the responsible person’s mobile number requested?** So that a real person within the company can be reached. It must be a genuine mobile number, not a virtual number bought from a platform. **Do I need a London address for a 020 number?** The rule requires a valid UK address, without requiring it to be within the area code’s zone.
