United Kingdom calling code: +44

The short answer is +44. The useful answer is: what do you dial from your country, and what should you do with leading zeros?

Dialling notes for United Kingdom

The UK uses the +44 calling code. UK numbers are often written with a leading 0 domestically (the trunk prefix). When calling the UK from abroad, you typically drop that leading 0 and dial +44 instead.

Emergency numbers

999 Also: 112

Non-emergency medical: 111

Non-emergency police: 101

111 is the NHS non-emergency medical number. 101 is the non-emergency number for police (UK).

999 and 112 both connect to the UK emergency services.

Emergency numbers can vary by region/provider — if you’re travelling, check locally when possible.

Tips

Domestic UK format often starts with 0 (e.g. 020…, 07…). International format typically removes that 0.
UK mobile numbers usually start with 07 domestically; from abroad that becomes +44 7…
If you’re calling from a mobile, using +44 is the simplest option (no need to know your exit code).

Common mistakes

Dialling +44 0… (keeping the domestic 0 after +44) — this often fails.
Mixing spaces/punctuation into a tel: link instead of a clean E.164 number.
