You are not required to take any further action after receiving a mismatch from Self Check but resolving an SSA mismatch now gives you the peace of mind that your employment eligibility records are in order.
If you wish to resolve an SSA mismatch, you would need to visit an SSA office with the “Notice of Mismatch” generated by Self Check. It provides a set of detailed steps on how to follow up on your potential mismatch.
You should not contact the Social Security Administration about Self Check unless you have received an SSA mismatch.
