The phone number is 410-965-0160 they are available 6am to 9pm ET. I was on hold for a little over 10 minutes before the agent was able to assist.
In addition to the form being mailed next week I asked about if it was possible to complete the form over the phone or if that was an option. I was advised it is not an option that service is for someone who’s benefits have been suspended not for someone who does not want to mail the form back.
i was also able to update my address with the agent without having to send an email to Manila and hope they respond. All in all a very nice call
