Once an application is filed, the Social Security Administration must verify the accompanying documentation with the application, so it generally takes about 10 days from the date the administration receives the application, explains the SSA. It is possible to apply in person or by mail.
To apply for a Social Security card, there is no charge. The application must include the required documents, and a list of these documents is available online at SSA.gov. Applicants must fill out an official application for the Social Security card, and then file or mail it, along with the required documentation, to a local Social Security office, explains the SSA.
