Yes, you can still report your 90 days stay online if you meet certain conditions. You must be within 15 days of your reporting deadline, or longer than 7 days in advance according to most offices. However, this option is not available for the first report after returning to Thailand or for a first report with a new passport. You can access the online notification service through the Immigration Bureau's website at [this link](https://www.immigration.go.th/) or directly at [this reporting link](https://tm47.immigration.go.th/tm47/#/login).
