Call UK 0800 and 03 Numbers From Abroad
You're abroad and need to call your UK bank, HMRC, or the pension service. The number starts with 0800, 0345 or 0300. From a foreign phone, it either won't connect or costs a fortune.
Here's which UK numbers work from abroad, how to dial them, and what to call instead. You can call any of them from your browser with 002call.

Which UK numbers work from abroad
| Starts with | What it is | From abroad |
|---|---|---|
| 0800, 0808 | Freephone | Usually blocked. Use the company's +44 overseas number |
| 0300, 0330, 0345, 0370 | Non-geographic, priced like a landline | Often works as +44 3… |
| 0843, 0844, 0845, 0870, 0871 | Business rate | Often blocked from abroad |
| 01, 02 | Normal landline | Works as +44 1… or +44 2… |
These are the usual rules. The company decides whether to accept calls from abroad, so a number can still fail.
How to dial a UK number from abroad
Add +44 and drop the first 0.
0345 788 8444becomes+44 345 788 84440161 931 9070becomes+44 161 931 9070
Don't dial +44 0…. The extra 0 stops the call from connecting.
What to call instead of an 0800 number
Most UK banks and government services publish an overseas number that starts with +44 1 or +44 2. Here are some from our service number guides:
| Organisation | Overseas number | Guide |
|---|---|---|
| HMRC (Self Assessment) | +44 161 931 9070 | HMRC from abroad |
| State Pension (International Pension Centre) | +44 191 218 7777 | State Pension from abroad |
| Barclays | +44 2476 842 099 | Barclays from abroad |
| Lloyds | +44 1702 278 270 | Lloyds from abroad |
| NatWest | +44 3457 888 444 | NatWest from abroad |
| HSBC UK | +44 1442 422929 | HSBC UK from abroad |
| Nationwide (lost credit card) | +44 2476 43 89 96 | Nationwide from abroad |
Each guide lists hours and what the line is for.

- Enter the number with
+44and without the first0. - Check the rate. Calls to UK landlines cost $0.02 a minute.

Bank and HMRC calls often mean a long wait on hold. On a laptop, keep it plugged in. On a phone, stay on Wi-Fi.
Frequently asked questions
Can I call an 0800 number from abroad? Sometimes, but usually not. Many 0800 lines only accept calls from UK networks. Use the overseas number if there is one. See calling toll-free numbers from abroad.
Do 03 numbers work from abroad? Often, yes. Dial them as +44 3…. If one won't connect, look for a +44 1 or +44 2 alternative on the company's website.
Why is calling the UK from my mobile abroad so expensive? Your carrier may charge roaming plus an international rate. A browser call over Wi-Fi avoids both.
Is 002call free? Every new user gets a free test call of up to one minute. After that it's pay as you go, and credits never expire.
