Social Security and Mailing Address flagged as Commercial

Social Security has teleservice centers located in major population centers from east to west coast.

They have several hundred employees in each location. They take and process applications for benefits and process post entitlement actions. When you call SSA via the toll free number this is who you get.

I got this from someone with 38 years experience with the SSA. Most business can be handed by phone. They will tell you when a in office visit is necessary.
