At Lillian Purge, we specialise in Local SEO Services and provide guidance on how can i find my landline number so you never miss a customer contact or business opportunity.

Many modern home or office phones display the phone number when you pick up the receiver or check the menu.

  1. Plug your landline phone into the main wall socket if it isn’t already connected.

  2. Wait for the dial tone.

  3. Look at the screen   some models automatically show the number, while others display it under a “Menu” or “Settings” option.

If your phone doesn’t show it immediately, try using another method below.

Use your phone’s built-in number service

Most UK networks have a free automated service that reads out the phone number connected to your line. To use it:

  1. Pick up your landline phone and ensure you have a dial tone.

  2. Dial 17070 (works for BT, Sky, Plusnet, and many others).

  3. Listen to the recorded voice   it will announce your number.

This method is fast and works for the majority of UK landline providers. However, if it doesn’t work, your provider may use a different access code, so it’s worth checking their website or contacting customer support.

Check your broadband or landline bill

If you receive a paper or email bill from your provider, your landline number will usually be printed on it. Look for headings such as “Telephone Number,” “Account Details,” or “Line Information.”

If you manage your account online, log in to your provider’s customer portal and look under “Services,” “My Account,” or “Broadband and Phone.” The number will often be listed alongside your connection details.

Look at your broadband router or welcome pack

When you first set up your broadband or home phone service, your provider will have sent an activation email, text, or printed document. Your number is often included in this welcome information.

Some routers, especially those from BT or Sky, also have stickers on the back or underside showing your landline number along with the broadband network name.

Check a previous phone or contact list

If your landline has been connected for a while, your number might be saved on an old contact list, in your mobile phone, or in an email signature. It’s worth searching your saved contacts under your own name or home address to see if the number was stored automatically.

Call another phone

One of the simplest ways to find your landline number is to call your mobile or another nearby phone. When your mobile rings, your landline number will appear on the screen.

Keep in mind that this method only works if your caller ID is not withheld. If your landline is set to hide its number, you can temporarily override this by dialling 1470 before the number you want to call. For example, dial 1470 07XXXXXXXXX to reveal your number.

Contact your service provider

If none of the above methods work, the surest option is to contact your landline provider directly. Customer service teams can verify your account and confirm your number quickly.

Be ready to provide identification details such as your account number, billing address, or payment information. Most providers can also text or email the number to you once verified.

Why it’s important to know your landline number

Knowing your landline number is essential for several reasons:

  • Customer communication – If you use your home line for work or business, you’ll need the number for marketing, directories, and customer calls.

  • Emergency use – Emergency services can locate your address more easily if you call from a registered landline.

  • Broadband support – Some broadband services are linked directly to your phone line, so technicians may ask for your number when troubleshooting.

Having it written down and stored safely helps prevent issues later on.

Expert advice

If you’ve recently switched broadband or landline providers, you may have been given a new number or retained your old one through number porting. Always double-check after a move or service change to make sure you’re giving out the correct contact details.

For businesses, make sure your landline number is consistent across your website, Google Business Profile, and online directories. Consistency strengthens your local SEO presence and ensures customers can reach you easily.
