0800 FREEPHONE NUMBERS
0800 Freephone Numbers for UK Businesses
Make it easier for customers to call your organisation with an 0800 freephone number. UKDDI lets you choose an available number and then deliver incoming calls to the business phone setup that fits your team.
QUICK ANSWER
What you need to know
0800 numbers are UK freephone numbers. Calls from UK consumer landlines and mobiles are generally free to the caller, while the organisation receiving the call pays the relevant service charges under its provider tariff. They are commonly used for sales, support and national response lines.
CHOOSING THE RIGHT OPTION
Why choose an 0800 number for your business?
Freephone can be a strong fit where you want the customer’s decision to call to be as simple as possible.
Create a UK-wide contact point
Unlike a geographic number, 0800 does not associate the business with one particular town or city.
Use a dedicated campaign or department number
Publish a separate 0800 number for a sales campaign, helpline or support team while routing calls to the appropriate destination.
HOW IT WORKS
Connect your 0800 number to your existing phone setup
You do not need to replace every part of your phone environment just to add a freephone contact number.
0800 to SIP trunk
Deliver the number to a compatible PBX or 3CX environment using SIP.
0800 to hosted VoIP
Use a hosted service when the receiving team needs extensions and cloud-based business calling.
0800 call divert
Route incoming freephone calls to an existing UK landline or mobile for a simpler deployment.
BUSINESS BENEFITS
Plan the cost of receiving 0800 calls
Because the caller does not normally pay for the call, the receiving organisation should understand its inbound charging and expected call volumes before promoting an 0800 number heavily.
Check the live service pricing
Review the number rental, selected delivery service and applicable call charges during the UKDDI order process.
Match the number to the right team
Good routing reduces unnecessary transfers and helps make inbound call handling more efficient.
Use a memorable number where available
Patterns can make an 0800 number easier to recognise in advertising, but inventory is subject to availability.
