I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
I'm glad that your are interested in our service! In addition to what Ann154 stated, you can confirm if your number is portable by visiting: http://bit.ly/qDhvBY . I hope this information is helpful. Please let me know if you have any additional questions or concerns.
