Usually, eBay requires you to provide a formal proof of address to confirm your address and identity. Social security proof is generally not a recognized proof of address because it cannot prove your residential address. It is recommended that you provide other documents as proof of address, such as bank statements, utility bills, etc.

If you do not have other proof of address, you can try to contact eBay customer service and explain your situation to them to see if there are other acceptable documents.
