UK 0800 numbers, often called freephone or non-geographic numbers, are widely used by businesses, charities and government agencies to offer a free-to-call number within the UK. Since 2015, thanks to Ofcom regulation, calling 0800 numbers from UK landlines and mobiles is free, with the cost covered by the recipient.
But what happens when you try to call these numbers from outside the UK? Are 0800 numbers still free when dialed internationally? This guide explains the costs, how to dial correctly from various countries, and why having an 0800 number can benefit your business.

What are 0800 Numbers and why are they free in the UK?
0800 numbers are special non-geographic telephone numbers in the UK that businesses use to project a national presence. Instead of a local area code, these numbers provide a consistent number nationwide and are free for UK callers because the receiving business pays for the call.
Many organisations utilise 0800 numbers as professional helplines, customer support lines or free information hotlines. The UK telecom regulator, Ofcom, mandates the free-calling status for these numbers to promote accessibility.
Are UK 0800 Numbers free to call from abroad?
While 0800 numbers are free to call from inside the UK, this does not extend to international callers. If calling from abroad, such as the US, Canada, Australia, or Thailand, you will typically pay international call charges based on your phone provider’s rates.
Businesses usually specify on their websites that 0800 numbers are only free to UK callers. The cost for international callers depends on your telecom provider and varies by country.
