Details:The Numerical Identification Files (NUMIDENT), 1936–2007, series contains records for every Social Security number (SSN) assigned to individuals with a verified death or who would have been over 110 years old by December 31, 2007. There are three types of entries in NUMIDENT: application (SS-5), claim, and death records. A NUMIDENT record may contain more than one entry. Information contained in NUMIDENT records includes: each applicant's full name, SSN, date of birth, place of birth, citizenship, sex, father's name, mother's maiden name, and race/ethnic description (optional). NUMIDENT includes information regarding any subsequent changes made to the applicant's record, including name changes and life or death claims. The death records in NUMIDENT do not include any State reported deaths in accordance with the Social Security Act section 205(r). There are 72,182,729 SS-5 records entries; 25,230,486 claim record entries; and 49,459,293 death record entries.See https://catalog.archives.gov/id/12004494 for more information.Related Data:Visit the CenSoc Project for public micro datasets linked to NUMIDENT: https://censoc.berkeley.edu/.

Database System of Record for SSA Enumeration data.

NOVU is a mainframe application that accesses the NUMIDENT to perform real-time SSN verifications. This program is called by other SSA online programs that serve as interfaces to end-users. Some of the systems that use NOVU for verification purposes include Social Security Number Verification Service (SSNVS), Social Security Online Verification (SSOLV) and State Online Query (SOLQ). The input record is passed to NOVU with the goal of verifying that the SSN is valid and the corresponding name, DOB and/or sex match with certain tolerances. The NOVU verification response codes are returned to the requester.

The Internet Claims application (formerly known as Ready Retirement and the Internet Social Security Benefit Application (ISBA)) allows claimants to complete and submit applications for retirement, disability and aged spouse's benefits via the Internet. A part of the i-Claims processing includes establishing proof of age and proof of citizenship for applicants using SSA's main data stores (ICD, MBR, SSR and NUMIDENT). VSB is responsible for the NUMIDENT Utility Subprogram which compares the information submitted by the application to the data stored on the NUMIDENT to establish POA and POC. The utility also applies a tolerance for analyzing several data fields on the NUMIDENT in conjunction with each other to further improve the likelihood of establishing eligibility.

Through an automated confirmation system, an employer matches information provided by a new employee (Form I-9) against existing information contained in Social Security Administration's (SSA) and the Department of Homeland Security's (DHS) U.S. Citizenship & Immigration Services (USCIS) databases. The SSA E-Verify System (SSA E-Verify) determines a specific verification code based upon information (SSN, DOB, L-Name, F-Name) in the NUMIDENT database. The verification code is returned to DHS E-Verify (DHS E-Verify) along with the original verification request. The message to the employer is determined by DHS E-Verify based on SSA's verification code.

Numident - The RRB sends an annual file to SSA for SSN validation. The file contains SSNs for new hires to the rail industry.

Database for several Social Security Number Verification Systems that verify SSNs against the Numident.

DEVO is the back-end application for processing SSN verifications and data exchanges. DEVO uses modern technology for parameter driven processing of both batch and real time requests. DEVO provides the capability for SSA to accurately and rapidly respond to customized requests, legislative mandates, and court orders. Legacy verification and data exchange applications (Enumeration Verification System (EVS), Numident Online Verification Utility (NOVU), State Verification Exchange System (SVES), and State Online Query System (SOLQ) are methodically being reengineered into DEVO, which will make use of reusable, flexible software. DEVO interfaces with the Verification Account Management System (VAMS) to determine account status, obtain processing parameters, and store transaction counts for Management Information (MI).

The Affordable Care Act (ACA) is a federal statute enacted with a goal of increasing the quality and affordability of health insurance. Through a web service, CMS sends applicant information to SSA. SSA matches applicant data to various SSA data sources and provides a response back to CMS, based on the results of the matches. The results of these matches help CMS and states determine an applicant's eligibility and cost for health insurance. SSA provides results to CMS for matches of SSN, Name, and DOB against the Numident. SSA may also provide incarceration data from PUPS, Title II income from the MBR, and quarters of coverage data from the MEF.

GUNSCHIP and GUNPUC03 are general utility programs that read and retrieve NUMIDENT data. Many Social Security Administration on-line applications use these utilities to obtain number holder information from the NUMIDENT. The on-line applications pass a Social Security Number (SSN) to the GUNSCHIP or GUNPUC03 utility that reads the NUMIDENT and if the SSN IS found, returns selected data elements to the on-line application. The returned data includes Number Holder Name, Other Name, Date of Birth, Birth City, Birth State, Birth Country, Mother's Name, and Father's Name. The GUNSCHIP utility additionally provides the Citizenship Code, Form Code, Interview Code, Foreign Birth Indicator and Special Indicators (SPINs). Some of the applications that use the utilities are Customer Help and Information Program (CHIP), Customer Service Record Query (CSRQ), Disability Insurance Benefit (DIB), Division of Client Services Application Development (DCSDAD), Division of Electronic Processing Support (DEPS) and Personal Earnings Benefits Estimate Statements (PEBES).

SSNVS is a service offered by SSA's Business Services Online (BSO). It is used by employers and certain third-party submitters to verify the accuracy of the names and SSNs of their employees for wage reporting purposes. With SSNVS users may verify up to 10 names and SSNs online for immediate results or upload batch files for overnight processing. SSNVS uses the Numident Online Verification Utility (NOVU) for the online requests and EVS for the batch requests. SSNVS is maintained by OSES and both NOVU and EVS are maintained in OEEAS DIVES Verification System Branch.

The SSN Verification Service is used by Java applications to execute the GUVERF02 service using the WebSphere/CICS Interface. It accepts several input data fields like First Name, Last Name, and Mother's Maiden Name and compares the data to the corresponding fields on the Numident record. SSN Verify Service can be invoked from WebSphere only through the CMM infrastructure. The Numident record is retrieved by calling the GUNSCHIP general utility. This service is currently being used by the appointment application to match input data with the information on the Numident.

The SCHIP project implements the legislative requirements of Public Law 111-3, which requires SSA to provide a means for states to check SSA's records to see if they contain data to support an allegation of U.S. citizenship for new applicants under these programs. SCHIP records come into SSA via the State Verification and Exchange System (SVES). SVES records are processed through EVS Processing Code 322 for verification. EVS matches the applicant's Names and SSNs to the NUMIDENT and returns the information back to SVES. For SCHIP, EVS will also obtain citizenship data from the NUMIDENT. SVES returns a response code to the state indication whether SSA records are consistent with an allegation of U.S. citizenship.

The CenSoc WWII Army Enlistment Dataset is a cleaned and harmonized version of the National Archives and Records Administration’s Electronic Army Serial Number Merged File, ca. 1938 - 1946 (2002). It contains enlistment records for over 9 million men and women who served in the United States Army, including the Army Air Corps, Women's Army Auxiliary Corps, and Enlisted Reserve Corps. We publish links between men in the CenSoc WWII Army Enlistment Dataset, Social Security Administration mortality data, and the 1940 Census. The CenSoc Enlistment-Census-1940 file links these enlistment records to the complete 1940 Census, and may be merged with IPUMS-USA census data using the HISTID identifier variable. The CenSoc Enlistment-Numident file links enlistment records to the Berkley Unified Numident Mortality Database (BUNMD), and the CenSoc Enlistment-DMF file links enlistment records to the Social Security Death Master File. For enlistment records in the Enlistment-Numident and Enlistment-DMF datasets that have been independently and additionally linked to the 1940 Census, we include the HISTID identifier variable that can be used to merge the data with IPUMS census data.
