The Social Security Number (SSN) is essential for any U.S. resident, as it is key to working legally, accessing health care, paying taxes, and more. In this guide, we’ll explore what a Social Security Number is, who is eligible to get it, and how you can process your Social Security Number, including the recent ability to get Social Security online.
What is the U.S. Social Security Number
The Social Security Number is a personal identification issued by the Social Security Administration (SSA) in the United States. It is vital for the administration of social security benefits, so every citizen or resident must have one assigned.
What is the Social Security Number for?
The Social Security number (SSN) is crucial in various aspects of daily and administrative life in the United States, extending its usefulness beyond simple identification. Here we detail its main uses and why it is so necessary:

Acquiring employment in the USA
To work legally in the United States, every employee must have an SSN. Employers use this number to report wages to the federal government and for Social Security and Medicare tax reports. Without an SSN, payroll and tax transactions are virtually impossible.
Access to medical services and insurance
The SSN is used by health insurance companies to verify coverage and eligibility for medical benefits. In hospitals and clinics, the number helps access necessary medical services and process insurance claims. In addition, to enroll in Medicare, which is the federal health insurance program for people over the age of 65 or with certain disabilities, you are required to have an SSN.
Enrollment in universities and colleges
Educational institutions in the United States frequently require an SSN to process applications for admission, verify eligibility for scholarships and federal financial aid, as well as to manage student records. In many cases, it is essential to access student and administrative services.
Processing other official IDs
The SSN is required to apply for other identification documents in the United States, such as a driver’s license and U.S. passport. State and federal agencies use the SSN to effectively verify a person’s identity and to make sure records are accurate.
Importance in tax collection
The Internal Revenue Service (IRS) uses the SSN to track people’s income and ensure they meet their tax obligations. It is an essential component of the annual tax return, allowing the federal government to ensure compliance with tax laws.
How to Apply for a Social Security Number
To apply for a Social Security Number (SSN), it is essential to meet certain eligibility criteria set by the U.S. Social Security Administration. Here we detail who is eligible and what documents you need to complete your application:
SSN Eligibility Categories
Permanent residents: If you have a green card, you are eligible for an SSN. The Green Card identifies you as a lawful permanent resident of the United States, allowing you to work and reside permanently in the country.
Work/Investor Visa Holders: If you are in the U.S. under a work visa (such as H-1B, L-1, O-1, among others), you can apply for an SSN. These visas indicate that you have permission to work in the United States for a certain period of time.
Refugees and asylees: If you have been admitted to the United States as a refugee or asylee, you have the right to apply for an SSN. These categories protect individuals who have been displaced for reasons of security, persecution or conflict in their home countries.

Documents required to apply for the SSN
Valid passport: Your passport must be valid and is the main internationally recognized identity document. It is used to verify your nationality and identity during the SSN application process.
Work Visa or Employment Authorization Document (EAD): If you are in the U.S. on a work visa, this document is necessary to prove that you have legal permission to work. If you do not have a work visa, but you do have a permit to work, you will need the EAD, which is issued by the United States Citizenship and Immigration Services (USCIS).
Form I-94: This form is your U.S. Arrival/Departure Record and shows your immigration status and how long you have permission to stay in the country. It is crucial to prove that you entered the country legally and what your current status is.
How to Get a Social Security Number
The process for obtaining a Social Security Number is administered by the Social Security Administration (SSA), the U.S. government agency responsible for administering Social Security benefits. Here we explain each step in detail:
Step 1: Complete Form SS-5
Form SS-5 is the official document for applying for a Social Security Number. You must fill it out with accurate information about your identity, immigration status, and work in the United States. You can download it from the official SSA website or pick it up at one of their local offices.
Step 2: Apply in person
Once you have all your documents and the SS-5 form completed, you must submit your application at an SSA office. It is advisable to schedule an appointment through their website to minimize wait time and ensure faster service.
Step 3: Receiving Social Security Number
After you submit your application, the SSA will process your paperwork and, once approved, mail your Social Security card to the address you provided on the form. This process can take a few weeks, depending on the workload and volume of applications at the SSA.
Step 4: Activate Social Security Number
When you receive your Social Security card, it’s important to verify that all information is correct (such as your name and Social Security Number). If you find any errors, you should contact the SSA immediately to correct them. There is no formal “activation” process for the Number, but you do need to make sure it’s properly registered in your name and start using it responsibly.
Get Your Social Security Number Efficiently
Applying for and obtaining a Social Security Number is an essential step for integration into U.S. society and economy. Knowing the requirements and the correct process can significantly simplify your immigration experience.
