In 2025, 0300 numbers have firmly become established as non-geographic numbers in the UK. From within the UK, they’re charged the same as calling a standard landline (01 or 02). Most mobile providers also include them in bundled minutes, following rules introduced to make calling costs clearer and fairer for consumers.
But what happens if you’re abroad and want to call a 0300 number? Will you pay more, or is it still treated like a standard UK call?
Calling 0300 Numbers From Abroad in 2025
From outside the UK, 0300 numbers are treated the same as any UK geographic number. That means:
- You’ll pay the international rate to the UK from the country you are in.
- There is no special surcharge just because the number begins with 0300.
- Costs depend on your local operator and roaming plan.
- So, whether you’re in Germany, the US or Australia, you’ll be charged the going international rate to call a UK landline.

What to Check Before Calling?
- Roaming terms
Some roaming bundles include calls to UK numbers, but not all. Double-check your package before dialling. - Connection fees
Certain providers charge a one-off fee to connect an international call, on top of the per-minute rate. - Inclusive packages
If you’ve bought an international add-on, your call to a UK 0300 number may already be covered.
In Conclusion
- Abroad, 0300 numbers are treated the same as UK landlines.
- You’ll pay the standard international rate to the UK from your current country.
- There is no additional “0300 surcharge” — but roaming and setup fees can still apply.
- Always check your provider’s international call terms before travelling to avoid surprises.
