If you can’t look up your ID following the above steps, please send us an inquiry to our Help Center (email@example.com) with specific details and we’ll try our best to provide support.
1. It’s not possible to look up your ID with just your basic information (e.g. Name, Phone Number, Date of Birth, etc.).
2. To look up your ID, we may need your connected partner’s help.
