@arth You will need to log into your Allstarlink portal, click on node settings, then your node number, then extend node number (NNX). this will convert it to the six-digit format that you described, with the first five digits you see now, plus a 0 for the first, 1 for the second, up to 9 for the tenth node number. You can add up to ten nodes to this node extension fully automated and with no support request or wait time. You will not be able to preserve the five-digit node number as it is now. Additionally, you can initiate a manual request for a second ASL node, which they will generally issue, and you can then keep one of your nodes as a five-digit number, and extend the other to a six-digit node, and have ten additional nodes off this six-digit number. HTH.
