What are 0345 numbers?

Buy 0345 Numbers

The use of 0345 numbers is becoming very popular in the United Kingdom. These are landline telephone numbers that are special because they cannot be associated with any geographical area of the United Kingdom. It is not possible to find out where the landline number is that you are trying to call or receiving a call from by looking at the number alone.

0345 numbers are non-geographic numbers (NGNS) used by many large organisations. 03 numbers such as 0330, 0333, 0345 and 0370 are included in your monthly landline or mobile minutes. Otherwise, 0345 numbers are charge at a local rate (the same call charge as to a 01 or 02 number). Ofcom regulations require telephone number providers to treat 03 numbers identically to 01 and 02 numbers whether you are calling from landline or mobile. This is why many businesses are changing their 0845 number for an 0345 number; this includes governmental departments, shops, banks and many SMEs.

Why choose an 0345 number?

The cost is the main reason that most businesses use an 0345 number, as it has advantages for their customers or clients. Dialling an 0345 number costs the same if you are phoning a landline number at a home or business using normal ’01’ or ’02’ number. You will be charged the same using an 0345 number as these.

Many mobile phone companies include 0345 numbers in your monthly number of voice call ‘minutes’, if you have them. This means that providing you have enough minutes left, you will not incur any additional charges for calling an 0345 number. This can be very helpful.

Similarly, your home landline call package may include free calls to other landlines at certain times of the day or week. For example, you may have free calls on the weekend or during the evening. If this is the case and you call an 0345 number during these times you will not incur any additional charge. However, if you call the 0345 number outside of the free period, you will be charged for making the call. The call charge would be the same as if you were phoning a normal ’01’ or ’02’ number.


What do people think of 0345 numbers?

Many people consider 0345 numbers to be ‘free’. However, they are not free, but many people do not realise this because they do not get charged any extra for making the call to the 0345 number. They are not the same as ‘0800’ or ‘0808’ numbers therefore.

There are several varieties of 0345 numbers. All numbers that start ’03’ can be considered to have the same way of call charging. If you or your business would like to get an 0345 number, they can be set up in minutes when you purchase through Number Supermarket.
