A second phone number, on the phone you already have

If you run a business from your own mobile, sooner or later every customer has your personal number. A second phone number fixes that: customers ring the business number, and your own number stays private.

You do not need a second phone, a second SIM or a dual-SIM handset. Digital Numbers gives you a real UK number that works in an app on the mobile you already carry.

How a second phone number app works

1. Choose your number. Pick a local area code, such as 020 for London or 0161 for Manchester, or a UK-wide 033 number.
2. Start your free trial. The number is active as soon as you sign up.
3. Install the Digital Numbers app on your iPhone or Android phone. Calls to your second number ring in the app, and when you call out from it, people see your second number, not your personal one.

Prefer not to use an app? Forward calls to any phone, and change where they go at any time.

Why have a second number

• Keep your personal number private. Put the second number on your website, van and invoices.
• Switch off after hours. Set working hours for each day. Outside them, callers go to voicemail.
• Look local. Choose a local area code, so customers see a number from their own area. See virtual landlines.
• WhatsApp Business ready. Run WhatsApp Business on your second number and keep personal WhatsApp on your own. See WhatsApp Business numbers.

What to look for in a second number

• A number you keep. Free second-number apps often recycle numbers that go unused. If customers will rely on it, choose a number that stays yours while you pay for it.
• Calls out with the second number, not just calls in, so you never reveal your personal number.
• Working hours and voicemail included.
• Clear pricing with no contract.
