A keying error occurs when the data on the paper Form SS-5 (not the system-generated
application) does not match the data keyed into Social Security Number Application
Process (SSNAP), as determined by the entry on the Numident (e.g., Form SS-5 shows
“06/21/50” and the Numident entry shows “06/12/50”).
Day and month reversals (e.g., 06/07/50 versus 07/06/50) are common errors that occur
when the DOB format on the Form SS-5 is dd/mm/yyyy but we process the DOB as mm/dd/yyyy.
To determine whether a keying error has occurred, compare the entry on the SS-5, or
microprint, with the data shown in the corresponding field on the Numident.
For instructions on how to read the Numident, see RM 10235.005.
For instructions on how to request microprints of Form SS-5s, see RM 10220.365.
NOTE: Use your judgment about whether to request a microprint based on how likely you consider
a keying error to be the cause of the incorrect DOB. For additional information on
correcting keying errors see RM 10215.051.
