Social Security office fax numbers in Colorado
These are the fax numbers Social Security published for its Colorado offices. Find the office handling your case, then send your documents from your phone.
Use your Social Security notice to find which office has your case. Social Security has moved almost every office to a toll-free fax line, so if your notice prints an older number, the one here is the more recent of the two.
