In today’s interconnected world, being able to reliably and cost-effectively connect with people across borders is more important than ever. From avoiding costly mistakes to finding the best deals on international calls, knowing the ins and outs of the UK’s dialing system can save you time, money, and frustration.

Frequently Asked Questions About Calling From The UK

How do I dial international numbers from the UK?

To dial an international number from the UK, you need to use the UK exit code (00), followed by the country code of the destination country, and then the local phone number. So, the general format is: 00 + Country Code + Local Number.

Calling internationally requires understanding a specific sequence. First, the ‘00’ tells the UK telephone network that you’re about to dial a number outside of the UK. Each country has its own unique country code; for example, the United States is ‘1’, Germany is ‘49’, and Australia is ‘61’. You can easily find the country code for your desired destination with a quick online search. After the country code, you enter the local number. It is important to remember to drop the leading ‘0’ from the local number if it exists, as that ‘0’ is only needed when calling within the UK. For example, if you were calling a number in the United States (country code 1) with the local number (555) 123-4567, you would dial 00 1 555 123 4567. Double-check that you have the correct country code and local number before dialing to avoid misdialing and potentially reaching the wrong person or country. Be mindful of time zone differences as well, to avoid calling at inconvenient hours.

What’s the UK exit code for international calls?

The UK exit code for making international calls is 00.

When you want to call a number outside of the United Kingdom, you must first dial the exit code. This signals to the UK’s telephone network that you are about to dial an international number. Without it, the system would interpret the digits you enter as a local or national call. Once you dial 00, you follow it with the country code of the nation you’re calling, and then the specific phone number.

For example, if you were calling a number in the United States (country code 1), you would dial 00 1 followed by the area code and the rest of the phone number. It’s crucial to remember the exit code, as it’s the gateway to connecting internationally. Note that mobile phones often allow you to use the “+” symbol as a substitute for the exit code. So, in the US example, you could also dial +1 followed by the area code and phone number from your mobile.

How do I call UK landlines from a mobile?

To call a UK landline from a UK mobile phone, dial the area code (including the initial ‘0’) followed by the local phone number. For example, to call a London landline, you would dial 020 followed by the eight-digit London phone number.

When dialling a UK landline, the crucial step is including the full area code. UK landline numbers are structured with an area code (which identifies the geographic region) and a local number specific to that area. Failing to include the area code will likely result in an incomplete or incorrect call. If you are calling from a mobile within the same area code as the landline, you *still* need to dial the area code, even though it might seem redundant. Remember that some area codes have changed over time, so if you have an old number, it’s best to verify the correct area code online or through directory services. Some newer services allow number lookups if you are uncertain, or dialling 118 will connect you to directory services.

Are there cheaper ways to call abroad from the UK?

Yes, several significantly cheaper alternatives to traditional landline or mobile phone calls exist for calling abroad from the UK. These options leverage internet-based technologies or specialized calling plans to drastically reduce costs compared to standard per-minute rates.

While dialing directly from your UK mobile or landline can be convenient, it’s almost always the most expensive way to call internationally. The high per-minute charges quickly add up. Instead, consider Voice over Internet Protocol (VoIP) services like Skype, WhatsApp, Google Voice, or Viber. These apps use your internet connection (Wi-Fi or mobile data) to make calls, bypassing traditional phone networks and resulting in much lower fees. Many offer free calls to other users on the same platform and competitively priced calls to landlines and mobile phones worldwide. Another cost-effective strategy is to use international calling cards or specialized calling plans offered by mobile providers or third-party companies. These often provide bundled minutes or significantly reduced rates for specific countries. Comparison websites can help you identify the most suitable plan based on your calling patterns and destination. Finally, if you’re calling a friend or family member abroad who also has a smartphone, using video calling apps like FaceTime or Zoom can provide a free and visually connected way to stay in touch, provided both parties have a stable internet connection.

What’s the area code for London when calling from within the UK?

When calling a landline in London from within the UK, the area code is 020. You must dial the full number, including this area code, followed by the eight-digit local number.

When calling a London landline from within the UK, it’s important to remember that you need to include the ‘020’ area code, even if you are also calling from within London. This differs from some other countries where the area code might be dropped when calling within the same region. Failing to include the 020 area code will result in your call not connecting. For example, to call the British Museum, whose number is 020 7323 8299, you would dial the entire sequence exactly as written, even from another landline in London. Mobile phone numbers do not use geographical area codes, and London mobile numbers are indistinguishable from the rest of the UK. You should always dial the complete mobile number, starting with 07, regardless of where you are calling from within the UK. So, if you’re calling a London-based mobile, you’ll dial the full 11-digit mobile number as you normally would.

How do I call a freephone number in the UK?

To call a freephone number (starting with 0800, 0808, or 116) in the UK, simply dial the full number from any landline or mobile phone within the UK. These numbers are free to call, meaning you won’t be charged by your phone provider for the call duration.

Freephone numbers are designed to be accessible to everyone, regardless of their phone plan. This means that whether you have a pay-as-you-go mobile, a contract mobile, or a landline, the call should be completely free. The cost of the call is borne by the organisation owning the freephone number, encouraging customers or potential customers to contact them without incurring any charges. It’s worth noting that calls to other non-geographic numbers (those starting with 084, 087, 09, or 070) are *not* free and can be quite expensive, particularly from mobile phones. Be sure to double-check the number you are dialing and confirm it starts with the freephone prefixes of 0800, 0808, or 116 to avoid unexpected charges.

What are UK mobile network prefixes?

UK mobile network prefixes are the initial digits of a mobile phone number that, while not directly identifying the network anymore due to number portability, historically indicate which network originally allocated the number. These prefixes typically follow the ‘07’ national dialling code and consist of two digits, such as 077, 078, 079, 074, etc.

While these prefixes were once closely tied to specific mobile networks like Vodafone, EE (formerly Orange and T-Mobile), O2, and Three, the introduction of mobile number portability (MNP) means that a number can be transferred to a different network. Therefore, relying solely on the prefix to determine the current network is unreliable. You can no longer assume that an 077 prefix always means a Vodafone number, for example. Despite the changes brought about by MNP, knowing the prefixes can still be helpful in some contexts. For example, certain services might use prefix information for routing calls or identifying potential fraud. However, for accurate network identification, you would need to use a dedicated number lookup service. These services consult databases that are updated regularly to reflect number portability changes. Even though the original allocation of number prefixes isn’t a guaranteed indicator of the current network, the 07 mobile prefixes remain a fundamental part of the UK numbering plan.
