What are 03 business numbers?

03 business numbers are UK-wide numbers that don’t tie you to a specific location. They’re great for UK businesses and entrepreneurs wanting a nationwide presence despite being based in one place.

With Rinkel, your 03 number comes with a suite of business features. From setting business hours to capturing call recordings, Rinkel gives you a hassle-free way to manage your business phone and features.

 

Why you need a 03 number for your UK business

Your business needs a professional line for customers to contact. Without it, they’re reaching your mobile and being greeted with “Hey, who’s this?” It’s not the first impression you want to give.

Nationwide numbers make your business more trustworthy across the UK. Your client might be calling your Nottingham-based business from Newcastle, but they don’t need to know that.

Give customers an experience they can trust from the get-go. If you’re a UK business looking to grow your presence and professionalism, Rinkel paves the way without the complicated setup and hefty price tag.

Smart and stylish solution! I've tried a few calling apps, but this one hits the sweet spot between functionality and good design. Worth every penny.

Way more professional than what I had before. I needed a UK number to appeal to UK clients and this app helped me with that main problem I had.. I use the personalised voice mail feature on the weekends which I recommend for anyone that needs the break like me :P

Literally had my business number set up in minutes. So happy to finally find an app for where I'm at with my business atm, everything else on the market was way too expensive or complicated.

No fluff, no confusing menus, just a simple app. Honestly one of the best designed small business tools I’ve found.

Frequently asked questions about national business landlines for mobile

What is a 03 UK number?

03 numbers are UK phone numbers that aren’t linked to anywhere specific. Instead of showing up as “Calling from Manchester” or “Calling from Belfast,” non-geographic landline numbers give businesses, public services, and charities a national presence that doesn’t tie them to a town or city.


How much does it cost to get a 03 number?

The cost of a 03 number depends on the provider you’re purchasing it from. Rinkel plans start at £7.99 per month. You get your 03 number included in your subscription, plus plenty of helpful business phone features—like call recording, business hours and caller queues.


How much does it cost to make calls from a 03 number?

The cost of using your 03 number to make calls depends on your chosen Rinkel plan:

  • Essential: 5p/minute
  • Professional: Unlimited calls (subject to our Fair Use Policy)
  • Expert: Unlimited calls (subject to our Fair Use Policy)
  • plus plenty of helpful business phone features—like call recording, business hours and caller queues.


What about porting my existing number to Rinkel?

Simple, one of the key features of using Rinkel’s phone system is that you’ll be able to transfer over any existing number you currently want to keep. Simply fill out the porting form to get started.


Can I have more than one business number?

Yes! You can add extra phone numbers to your Rinkel account for £3 per month per number. You’ll be able to manage all numbers in the Rinkel app and desktop webapp.


Can I make calls using a 03 number on a desktop?

    Frequently asked questions about how Rinkel works

    Rinkel is a smart, affordable phone solution made for entrepreneurs and small businesses. You can use Rinkel business lines on the phone you already use, and access extra features via the app and desktop environment. It doesn’t require any lengthy set-up or onboarding, just a three-step sign-up process that you can start right now.

    You can use Rinkel on your mobile phone or desktop (via My Rinkel, our Customer Portal). You can choose where incoming calls arrive in your profile settings.

    Outgoing calls with Rinkel are also simple. The in-app dial screen resembles your smartphone's native dial screen, so it’s something you’re already familiar with. To make a call with Rinkel, enter the app and dial the number (or select from your contacts). You’ll immediately receive an incoming call, which—when picked up—will start your outgoing call.

     

    You receive incoming business calls as you do every other call. Your phone rings, and you pick it up. Rinkel offers three options to help ascertain when you’re receiving a business call:

    1. It’ll show up as the name you´ve chosen for your Rinkel number, like for example “My business number”
    2. It’ll show up as the caller’s number
    3. It’ll show up as the caller’s number and then play you a short Rinkel message before the call (informing you that it’s on your business line)

    No, Rinkel uses your existing provider’s network on mobile—which is typically a stronger and more reliable VoIP alternative. You’re not dependent on an internet connection, and instead rely on the thousands of cellular towers dotted across the UK. This means high quality audio across more of the country—what’s not to like? 

    The only time you’ll be using VoIP technology is when making and taking calls on the My Rinkel desktop portal. Typically, this means you’ll be connected to your home or office WiFi, meaning you’ll be using your chosen internet provider for calls.
