'Docs received in mail center' means that you physically handled the customers 1583 and IDs in your location. We are not able to upload these customers to the BCG for you, since the documents were handled outside the iPostal1 system. Since we are unable to confirm the status of those customers that you handled in store, their status will remain as 'Docs received in mail center', even if they are in the BCG. We do not have access to those BCG records. When you add the customer to the BCG, you should then change the status to 'Compliant by Mail center'.
