The UK Emergency Number

World's oldest emergency number — introduced 1937

999 is the emergency telephone number for the United Kingdom and Ireland. It is the world's oldest emergency phone number, introduced in London on July 1, 1937. When you dial 999, you're connected to emergency services that can dispatch police, ambulance, fire, or coastguard to your location.

What is 999? The Full Story

999 was created as a direct result of a fire at a London building in 1935 that killed five people, partly because it took too long for neighbors to reach the fire station by phone. The Post Office introduced 999 as a dedicated emergency line, and on its first day of operation, it received its first call: a woman reporting a prowler.

Today, 999 handles around 11 million emergency calls per year in the UK. It is free to call from any phone — landline, mobile, payphone — and works without credit or a SIM card. The number is operated by BT on behalf of Ofcom.

👮

Police

Crime in progress, threat to safety, accidents

🚑

What Happens When You Call 999?

Here's exactly what to expect when you call 999 in the UK:

Step 1

"Emergency — which service?"

The BT operator answers first and asks which emergency service you need. Answer clearly: 'Police', 'Ambulance', 'Fire', or 'Coastguard'. If you're unsure, say 'ambulance' — they can redirect.

Step 2

Connected to the service dispatch center

You're immediately connected to the dispatch center for the service you requested. For ambulance calls, you'll reach your regional ambulance trust.

Step 3

Give your location FIRST

The most important information you can provide is your location. Give the full address, town, nearest landmark, or postcode. If you're in a car, give the road name and direction of travel. The dispatcher can still send help even if you can't complete the call, as long as they have your location.

Step 4

Describe the emergency

State clearly what has happened, how many people are involved, and any immediate dangers. For medical emergencies, the dispatcher will also guide you through first aid steps while help is on the way.

Step 5

Stay on the line

Don't hang up unless the dispatcher tells you to. They may continue to provide instructions and need to relay updated information to the responding units.
