# What Is a Phone Extension? Everything You Need To Know Written By: [Burner Team](/content/blog-author/burner-team/index.html) Reviewed By: [Elizabeth Thorn](/content/blog-author/elizabeth-thorn/index.html) ## **What Are the Different Types of Phone Extensions?** ### **Residential Extension** The first and simplest type of phone extension is a residential extension. Before cell phones became the standard, most residential households were serviced by a single telephone line. [During the height of landlines](https://www.theatlantic.com/family/archive/2019/12/families-landline-shared-phone/603487/), it was fairly common for there to be a few different devices being used. A single home might have a phone in the living room, kitchen, and/or bedroom, for instance. Each device would technically constitute a specific extension. The main issue with residential extensions is that they would only use a single phone line. Any incoming calls would make each individual device ring. Any device in the house could be picked up and used to answer the call or join in on the conversation. ### **Business Extensions** The second and most commonly used type of extension involves business. If you think that having several people inside a house use a single telephone line is hectic, then think about a company trying to use just one. Can you imagine the wait times if major corporations only used a single phone line to field customer calls? Fortunately, phone extensions can help customers reach the people who can most effectively help them more easily. (We will primarily be discussing this type of phone extension today.) ### **Off-Premise Extensions** The third extension refers to off-premises extensions. These extensions function in a similar way to business extensions. The critical difference is that they are typically located away from the headquarters or physical location of the business. By using [Voice Over Internet Protocol (VOIP) technology,](https://www.fcc.gov/general/voice-over-internet-protocol-voip) a business can create an off-premises extension to connect calls to any location around the world. It’s common for these types of extensions to be used for cell phones, so VIP connections can be reached at any time and at any location. ## **What Is a Business Phone Extension?** A business phone extension is a few digits that are assigned to a specific person, group, or department within a company. In other words, it’s a unique code that can be used to quickly contact a certain individual or team. These numbers typically range from a single digit to five of them. The numbers are highly customizable and can be assigned based on whatever system you would like. In most cases, each extension will be linked to the primary phone number of the business. That way, a customer can call one number and use it to be connected anywhere within the company. It also helps with internal communication by eliminating the need for employees to dial more numbers than the extension. By being a part of the internal network, they can simply dial the extension and instantly be transferred through. ## **How Do Business Phone Extensions Work?** The easiest way to understand a business phone extension is by using an example. Let’s say that the primary phone number for a business is (777) 555-1111. Anyone could reach the central switchboard of a company by dialing those numbers. From that point, they would have the option to enter the extension of the party they want to contact or wait for an operator to assist them. Let’s imagine that the caller needs to get in contact with an employee named Kevin. Kevin is an integral part of the customer service team and has his own extension of 999. To reach Kevin, the caller could either enter 999 when prompted or wait for an operator to make the transfer. In essence, Kevin would have his own number within the company of (777) 555-1111-999. ## **Options for Creating Business Extensions** You have a few ways that you can set up phone extensions within your freelancing business. There's really no right or wrong way to do it. It’s more a scale of more efficient or less efficient. Generally, you have three distinct options for creating a business extension: ### **Individuals** A specific person has a dedicated extension that reaches them directly. In businesses, these are reserved for very important people such as executives, managers, and operators. Not everyone needs their own direct line, so you would need to choose these individuals carefully. An extension for them could be created for their desk phone, business cell phone, their computer, or personal cell phone. ### **Departments** Ideally, each separate department within a business should have its own extension. If there’s a need for the department to exist, there’s a need for them to be contacted quickly. Typically, the extension for a department will be assigned to a centralized phone within the department. However, you could assign the extension to the phone of a manager who would field all calls made to the department. ## **Why Should You Use Phone Extensions for Your Business?** As a freelancer, you are the face of your business. Your clients rely on you to provide high-quality work and excellent customer service. One of the most important aspects of presenting a professional image to your clients is communication. Phone extensions, also known as virtual phone numbers, can offer several benefits for freelancers regarding professionalism, privacy, flexibility, and organization. ### **1. Professionalism** As a freelancer, you want to present yourself as a serious business person committed to your craft. When you use a phone extension, you create a dedicated phone line for your business, separate from your personal phone line. This gives the impression that you are a professional who takes their business seriously. ### **2. Privacy** In today's digital age, personal information can be easily accessible online. Using a phone extension can help protect your privacy by keeping your personal phone number separate from your business line. ### **3. Flexibility** Freelancers can often work from anywhere: be it in a home office or coffee shop. With phone extensions, you can take your business phone number wherever you go. ### **4. Organization** When you use phone extensions, you can set up different extensions for different clients or projects, making tracking your calls and messages easier. ## **Conclusion** Freelance jobs require a lot of time, effort, and dedication. To be successful, you’ll need to push yourself past limits that you didn’t know you had. It can be difficult to [turn your freelance business dreams into a reality,](/content/blog/4-simple-steps-realizing-business-dreams-phone-numbers/index.html) but it’s not impossible.
