If another user from another country/region signs up with the same username, Bumble will automatically assign them a different one before verifying their account. This prevents the issue of having 2 top-level profiles for the same name which may cause confusion when it comes to sending and receiving messages (that's why we recommend using your first or last initials instead!). We cannot change this once an account has been created so please choose something unique when creating your username! If you have questions about this then please contact us directly: support@bumble.com.
