How to add Extensions to your Phone Numbers

Do you make frequent calls to businesses where you have to enter an extension number in order to reach the person you are calling? If so, you can easily add the extension at the end of the number so you won’t have to enter it every time you call.

In this article I’ll explain how to add extensions to your phone numbers.

Firstly. I have to mention the two common ways that switchboards handle calls to extensions:

  • Most switchboards will answer your call and give you a list of menu options. If you know the extension number of the person you wish to speak with, you can dial it at any time without waiting for the message/menu to finish “talking”.
  • Other switchboards require you to listen to the entire recorded message before entering the extension number.

With that preliminary discussion out of the way, here’s how to append an extension number directly to the end of a telephone number on your smart phone:

  • So, if the switchboard at the business you’re calling allows you to enter the extension number at any time, simply add a comma followed by the extension number to the end of the phone number. For example, if you are dialling 01234-567-890 and then the extension 201, the number should look like as below:


  • If the switchboard requires you to listen to the entire message before entering the extension, use a semi-colon in place of the comma. In this case, the number should look like as below:


Note: If you use the semi-colon instead of the comma, a box will pop up with the extension already inside it. All you have to do us listen to the message, then tap Send Now for Android users or Dial for iPhone users at the appropriate time in order to complete the call.
