I followed all steps and added necessary documents needed to purchase DID as instructed here https://doc.didww.com/user-panel/identities.html
but now I’m not sure how to proceed. Do I wait for email from you guys that the documents have been approved or what is the next step?
Once the identity is created it should be assigned to ordered DID and only then submitted for verification:
choose ordered DID -> Select batch actions -> Assign end user details -> Select Identity -> Submit
After assigning identity to DID, verification process starts and it may be in following statuses:
Approved - indicates that end user details have been confirmed.
Pending - indicates that end user details verification process is pending.
Rejected - indicates that end user details have been rejected.
