Keep Your Number
If you are making the transition from an analog telephone to VoIP telephony, you will have the ability to keep the same telephone number when you change services. Even if you are moving to a different location, your number can remain the same, as VoIP service is not dependent on an exact location. This feature appeals to many people who have grown accustomed to their number or who use said number for business purposes.
How it Works
You may transfer your original phone number to your VoIP line when you sign up for service with a provider. This can usually be done when you are registering for your service online or on the telephone with a customer service representative. Many people keep their original phone number or choose their own area code for a new number, so VoIP providers make this process quick and seamless. If you would like to try out your new VoIP service before you make the phone transfer, that is no problem. Your number can always be transferred later, assuming that you still have your original phone service. Keep in mind that when you do make the transfer, it probably won't take effect for a few weeks. In the meantime, your provider will supply you with a temporary number.
What You'll Need
It is usually a simple process to keep your phone number when you make the switch to VoIP, even if you move to another location. However, there are some limitations. If you do move and decide to keep your old area code, this must be an area code where your VoIP provider offers service. In other words, you may not be able to keep the phone number you had in Japan when you move to America. Ask your VoIP provider for more details about the phone number you wish to choose when signing up.
Types Offered
Most, if not all, VoIP providers allow you to keep your phone number at no extra charge. This is often considered a basic feature with VoIP service packages and is an enticing aspect of the new technology. Companies like Lingo and Vonage make this a trouble-free process that can be accomplished online.
