Directory information — verify before you send. This fax number was compiled by automated research from public sources. It may be out of date, incomplete, incorrect, or in rare cases wrong entirely, and it is not confirmed by Social Security Administration. Before sending anything sensitive, confirm the number and receiving department directly with Social Security Administration, and consider sending a test cover page first. FaxFlow is an independent directory, is not affiliated with, endorsed by, or sponsored by this organization, and accepts no liability for reliance on this listing.

This appears to be a tax or government destination. These numbers change frequently and vary by form, state, and office. Confirm the current number on the official IRS or .gov page before sending — a misdirected filing can expose your SSN and miss a deadline.
