Doesn’t this defeat the purpose of a unified number? When you sign up it is to have one number for life that you can put on business cards, etc. Now they are killing mine…

We are sorry to inform you that your GrandCentral number (703) 552-xxxx will need to be changed as of August 25, 2007. As part of our beta testing, we are continually evaluating different solutions and partners to create the best quality service possible. Unfortunately, a very small number of users have been assigned numbers that are not performing to our quality standards and are being replaced with higher quality services. To ease the transition to a new number, we have already added (703) 942-xxxx as a replacement number to your account. Both of these numbers will ring your GrandCentral account until the 25th of August, at which point only the (703) 942-xxxx number will remain active. Your login and everything else regarding your account will remain the same, including all your settings, voicemails, and contacts. If you have any questions or would like to request a different number, please reply to this email and we’ll do our best to accomodate you.

Update:  I sent an email to GrandCentral expressing my frustration.  I was impressed when one of the founders of the company replied:

Matt,

I sincerely apologize for this inconvenience. I certainly understand your frustration and share it, but this is partly out of our control. The carrier who provides us with your number is stopping servicing this number and none of the other carriers we use can port it, otherwise we would have done it. We’re working on making sure this does not happen again in the future.

Thanks for your understanding and i hope we can keep you as a customer.

Vincent
