Explore the UK Phone Numbers Everyone Should Know

Smartphones are amazing devices. From making calls and exploring the internet to gaming and entertainment apps, it’s like a little computer in your pocket. Your phone is a vital tool, should you find yourself in an emergency or quickly need to get hold of important information, should you know the right numbers to call.

Here are 12 useful (and in some cases, life-saving) telephone numbers that everyone in the UK should know.


Are All UK Numbers 11 Digits Long?

Yes, almost all UK numbers are 11 digits long, including the dialling codes. There are a few areas around the country whose numbers only contain 10 digits, but these are in the minority. The combinations of UK numbers are:

  • 3-digit area code + 8-digit phone number
  • 4-digit area code + 7 digit phone number
  • 5-digit area code + 6-digit phone number
  • 5-digit area code + 5 digit phone number – if it is a 10-digit UK number


1: 123 (Speaking Clock)

BT launched their Speaking Clock service in July 1936 – a useful service in the days before you could just unlock the screen on your phone to check the time. Although it may no longer be seen by some as a useful service, you can still call the speaking clock and it is still used by many people, with around 30 million calls received annually. It can be a useful tool for those you are visually impaired or those who want to check the accuracy of their clocks.

The Speaking Clock is not a free service. It costs 50p a minute from BT landlines any time of day or night.


2: 141/1470 (Withhold/Provide Identity)

A withheld number is a number that isn’t visible to the person that is receiving the call. If you don’t want the receiver of your call to see your identity, for example: if you were calling back a number you don’t recognise and want to be careful, then you can call 142 to withhold your details. When the call appears on the recipient’s phone, your name won’t display and instead ‘Unknown’ will appear on the caller ID – even if they dial 1471 (the service that reveals caller numbers).

Dialling the number 1471, will reveal the number of the last call you received, unless they have opted with withhold it or the call came from a switchboard extension number. You can also return the call straight away by dialling 3 at the end of 1471. I’s free to use 1471 to find out the last number who called you, but it costs 35p charge plus the cost of the call, if you choose to return it.

Can you find out a withheld number?

There isn’t a specific way to reveal a withheld number, as this number is designed to hide the identity of the caller. If you are being harassed by an unknown number, you can block them through your telephone service provider.

Should you answer a number with no caller ID?

It’s best practice to avoid answering a call from an unknown number. It’s unusual for a number from a legitimate organisation to be withheld, so when you receive a call from a withheld number, it’s more than likely a scam. If you do happen to pick up a call from a number that does not display caller ID, it’s better to hang up as soon as you can, as this call may be charged at an extreme rate or anything you say when you answer the call may be used maliciously.

Can a no caller ID be traced?

Unfortunately, there is no guaranteed way for a person or a business to identify the origin of a call made with no caller ID, if the caller has purposely withheld the information. If you are worried about a call with no caller ID, it may be possible for law enforcement agencies to trace the call if you report it, but unfortunately there are no guarantees that they will be able to identify who it is. If you receive harassing or threatening calls you should always report them to the police.


4: 999 (Emergency Number)

The world’s oldest emergency telephone number, 999 was first introduced in London in 1937. Dialling 999 will take you through to one of the following emergency control centres: police, ambulance, fire or coastguard. Additional services can also be reached via the number. These include: lifeboat, mountain rescue, lowland rescue, cave rescue, moorland search and rescue, quicksand search and rescue, mine rescue and bomb disposal. If you have a speech or hearing impediment, you can sign up to the emergency SMS service. To do this, text “register” to 999 and follow the instructions.

Key Facts about 999

  • You can call 999 when your phone is locked, your balance is zero and even if you don’t have a SIM card.
  • If you dial 999 with no signal, your phone will look for signal on another network and use that to connect the call.
  • Around 30 million 999 calls are made each year.
  • Around half of calls require police with ambulances being the next most requested service followed by the fire brigade.


5: 999 + 55 (Silent Solution)

The Silent Solution offers a solution when you are in an emergency situation and you require police assistance, but are unable to speak. It was introduced to filter out accidental or hoax 999 calls and to offer a solution to certain situations, where the caller speaking may put them or others in danger. This process applies for calls made via mobile phones. When you dial 999, you will hear an automated police message that lasts for 20 seconds and starts with “you are through to the police”. It will ask you o press 55 to be put through to police call management. When you press 55 the operator will be notified and you will be transferred through to the police. Once transferred, the police call handler will attempt to communicate with you through ‘yes’ or ‘no’ questions. If you are still unable to speak, then the call handler will assess your call and provide instruction and arrange help, if needed.


Can the Silent Solution system be used via landline?

Due to the likelihood of a 999 call being made by accident via landlines, the silent solution is not used. If an emergency call is placed via a landline and the caller doesn’t speak, answer any questions or only background noise can be heard and the operator cannot decide whether an emergency service is required, then the call will be connected to a police call handler. If you replace the handset, the call may still be connected for 45 seconds, in case the caller picks it up again. When calls are made from a landline, information about the caller’s location should be available to the call handler to provide a response. There is no need to dial 55 after 999, as this process is automatic.


6: 101 (Police Non-Emergency Number)

101 is the national non-emergency police phone number. You can use 101 when you need the police but not an emergency response. As such, use 101 if you’ve had a minor traffic accident, for vandalised property, if your car has been stolen, if you suspect someone of drug dealing, if you’ve witnessed a crime, if you’ve seen a missing person or if you want to speak to a local officer.

Calls to 101 cost 15p per call.
