RM 10205: Social Security Number (SSN) Applications
TN 4 (10-09)
The number holder’s (NH) first and last name on his or her SSN card must agree with the first and last name shown on the document submitted as evidence of identity or legal name. A middle name or suffix is not considered part of the legal name. It does not matter if the middle name or suffix is included, omitted, or incorrectly shown on an SSN card.
For SSN purposes, a NH’s legal name consists of the first (or given name) and last (or family name or surname) that is used to sign legal documents, deeds, or contracts.
The SSN card has two lines for the NH’s name with 26 spaces on the first line for the NH’s first and middle names and 26 spaces on the second line for the last name and suffix, if any. Neither the first or last names shown on the SSN card should be reduced in length, unless it exceeds the 26-character limit. Therefore, omit middle names, middle initials, and suffixes if they prevent you from showing as many characters as possible for the first and last names.
