I checked and it doesn't look like you are required to complete any verification process at the moment. The team will let you know if there is a need for any verification process in the future.
I've been asked to submit my government issued ID and do a video call to verify my identity. But when I try to do it, I keep getting a 403N error. I've cleared cache and tried to use private browsing and nothing works. The chatbot is no help at all and I cannot find a customer service email.
I've noticed that the account you are currently posting with is not required to complete this verification process. You have a support ticket for the account that you are required to verify. Please make you that you are logged in to that account in order to complete the verification process. As a reminder, having multiple accounts is a serious violation of the Upwork Terms of Service.
I'm sorry for how this could've inconvenienced you. I checked and can confirm there's already a support ticket created for your case and one of our agents will be following up with you there. Kindly communicate through that ticket if you have any questions so that the team can assist you more effectively.
