Before work on first-owner account transfer, digital-service and delivery teams should name the reviewer and closure owner. Link first-owner account transfer to VIN, account, software version, and service country in the acceptance sheet rather than using only a model or project name. Check the service-coverage list, the account or version record, and the local test result for first-owner account transfer, then run activation and sign-out tests on a local phone or a test account, and sign the two conclusions separately. For vehicles whose owner account transfer is incomplete, state in the sales material the functions that cannot be enabled yet, and close account issues before delivery. Local personal-information rules for changes in owner account ownership are subject to destination-country authority requirements, licensed-institution rules, and the contract. Before closing first-owner account transfer, review the corresponding import checklist. If one document covers several software and account handover matters, record a separate accepted or open decision for first-owner account transfer.
