I haven't been with Numberbarn very long, but so far so good. I think it's great you can park a number for as long as you like for future use without having to get an expensive cell provider just to keep that number. Customer response has been quick. They display all customer FAQ quite well on their website. I only ported one number out so far and it went fast and smooth. I see what they mean by a port request expiring after a few days. I had an issue with T-mobile having trouble with a port expiring before the port can go through. You do need to ask for extra days on the port sometimes because the automated system will kick it out. I don't think most customers give this company a chance and understand the porting process can be different in every situation. I hope Numberbarn is around a long time.
