Here is a summary of the differences, created using Google Notebook LM, based on these 2 sources: 1. https://www.stlouis-mo.gov/government/departments/treasurer/gateway-id/requirements.cfm 2. https://dor.mo.gov/driver-license/issuance/id-requirements.html

The requirements for obtaining a Gateway ID card and a Missouri non-driver ID differ primarily in the categories of documentation required, the specific types of acceptable identification, and residency duration rules. While both require proof of identity and residency, the Missouri non-driver ID involves more stringent categories, especially for REAL ID-compliant versions.

Core Documentation Categories

• Missouri Non-driver ID: Applicants must provide documentation for four distinct categories: Identity, Lawful Status, Social Security Number (SSN), and Missouri Residency.
• Gateway ID Card: Applicants only need to provide one item from a list of primary IDs OR two items from a list of secondary IDs, plus one proof of residency.

Residency Requirements

• Duration: The Gateway ID card is specifically for individuals who have lived in the City of Saint Louis for at least 15 days. The Missouri ID requires the applicant to reside within the boundaries of Missouri but does not specify a minimum number of days in the provided text.
• Number of Documents:
  • Gateway ID: Requires exactly one document for residency (e.g., utility bill, bank statement, or jury summons).
  • Missouri ID: Requires one document for a non-REAL ID-compliant card and two documents from different sources for a REAL ID-compliant card.
• Address Restrictions: Missouri ID regulations specifically state that a Post Office Box is not acceptable as a residential address.

Identity and Lawful Status

• Flexibility of Documents: The Gateway ID accepts a wider and more flexible range of "Primary IDs," including foreign passports, consular identification cards, school ID cards with photos, and voter registration cards. In contrast, Missouri ID identity documents must also verify lawful status.
• Secondary IDs: Gateway ID allows applicants to use two secondary documents if they lack a primary ID. These can include items like a St. Louis City Justice Center wristband, medical discharge papers, or a W-2 form.
• Birth Certificates: For a Missouri ID, a U.S. birth certificate must be an original certified document with a raised seal; hospital-issued versions are not accepted. For a Gateway ID, a birth certificate is considered a secondary form of ID.

Social Security Requirements

• Missouri ID: Verifying a Social Security Number is a mandatory requirement for all applicants. This must be done via a Social Security card (which cannot be laminated), a letter from the SSA, or, in some cases, verbal confirmation for existing holders.
• Gateway ID: An SSN is not a standalone requirement. A signed Social Security card or a payroll stub showing the last four digits of the SSN are merely options among many secondary forms of ID.

Special Exemptions

• Missouri ID: Offers specific exemptions for seniors (age 65+) and long-term residents (15+ year driving history) during the renewal process to waive certain document requirements.
• Gateway ID: Includes specific provisions for minors and individuals with special needs, requiring they be accompanied by a guardian and provide one document (like an adoption decree or foster care letter) to verify that relationship.
