Need to look up your Social Security Number?
Effective June 24, 2013 the Social Security Administration updated the regulations concerning Social Security Number verifications. A replacement Social Security Number card will not be issued to non-U.S. citizens or residents who have no current need for a Social Security Number.
If you are a U.S. citizen or legal Permanent Resident Alien (“Green Card” holder) and you need to verify your Social Security number, please directly contact the Federal Benefits Unit, Embassy Tokyo.
If you are not a U.S. citizen or legal Permanent Resident Alien (“Green Card” holder) and you need to verify the details shown on your Social Security Number record, you must apply directly to the Social Security Administration for a printout of your Social Security Number record (known as a Numident). For more information, please visit SocialSecurity.gov.
