Part 1: What Are 03 Numbers?

The UK based 03 numbers are non-topographical. It simply means that these numbers are not specific to any location. Numbers that start with 03 are similar like any usual landline numbers. 

This format of number can be used by government organizations, different associations, and by any international organizations or business. For instance, if you want to make more leads for your business, or thinking of expanding your business internationally

If the answer to both of these questions is yes, then you can easily give a shot and try 03 numbers. With the help of 03 numbers, your consumers from all around the globe would be able to reach you without any international call charges. 

Part 2: Are 03 Numbers free to call?

Whether calling on 03 numbers is free or not depends upon your supplier. However, if you are calling 03 numbers from your mobile phone, then yes it will cost you nothing. 

According to the law of the UK government, it is mandatory for all the suppliers to include free calling minutes in mobile phone plans. In case you are calling 03 numbers from a landline, then it will cost you a national rate call according to your activated plan. 

If the service provider has included some free minutes in your landline calling plan, then it will be free. Beyond that, the national call charges will be applied for calling 03 numbers.

 Part 3: What Is the Cost to Call 03 Numbers?

Recently, these 03 numbers are introduced for businesses, private or government organizations, and the service providers. The demand for 03 numbers is increasing day by day. The reason behind it is the low calling cost. 

In case, you are trying to make a call to the 03 number from your mobile or landline, then the call rate depends upon your monthly plan and the service provider. For instance, if you don’t have any active plans or free minutes then you need to pay 10p to 40p per minute. 

These rates are according to the standard national calls. However, it may vary depending upon the service provider. If you are calling a 03 number from any other country, then it will cost you equivalent charges as your national call. 

Similarly, the only thing which you need to keep in mind while calling 03 numbers from outside the UK is that you need to skip the 0 from the number to which you want to make a call. Instead, dial +44 as the national code and then the remaining number.
