# On the Longbridge Securities app, register a Longbridge ID, then when choosing between opening a Hon

On the Longbridge Securities app, register a Longbridge ID, then when choosing between opening a Hong Kong account or a Singapore account, select to open a Hong Kong account. After starting or submitting the account opening process, this Longbridge ID can no longer be used to open a Singapore account. However, if you initially chose to open a Singapore account with that Longbridge ID, after starting or submitting the account opening process, you can immediately use the same ID to apply for a Hong Kong account. Why is this the case? I currently have two Longbridge IDs, each with one account—one ID has a Singapore account, and the other has a Hong Kong account. Each is bound to a different phone number. Now, I want to bind both to the same phone number, but it's not allowed because two IDs cannot be bound to the same phone number. So, how can I bind them to the same phone number? Should I first close the Hong Kong account and its ID, then apply for a Hong Kong account under the ID with the Singapore account? Is this the only way? Can I request to directly link the Hong Kong account under the ID with the Singapore account? Thanks, everyone!
