The information that you give to your new carrier, regardless of how it is done, must be accurate and match what your existing carrier has. If the information provided does not match, or is inconsistent, your request might be denied. This will cause delays and may result in downtime. Customers will not be able to reach your business.
You must be able to provide proof of ownership and information about the free telephone number. You should be aware of the requirements before you start the documentation process. This will allow you to be prepared and make the process faster by having all the necessary information.
Once all of these formalities have been completed your new carrier can submit a free number transfer request. Your current carrier will then release your number.
