What Is a Social Security Number?
Let me tell you directly: a Social Security Number, or SSN, is a nine-digit identifier assigned by the Social Security Administration to U.S. citizens, permanent residents, and certain non-residents. It tracks your income over time and determines eligibility for benefits like retirement and disability payments. Established in 1936 as part of the New Deal, its original purpose was straightforward—monitoring earnings for Social Security benefits—but today, you'll find it's required for much more, including tax filings, credit applications, and opening bank accounts. Remember, this number is key to your financial identity, so handle it carefully.
How Social Security Numbers Work
SSNs function as a universal tracker in the U.S. system. If you're a citizen, permanent resident, or even a temporary worker, you'll likely have one, as they're issued to nearly everyone here. The legal basis comes from the Social Security Act, and the SSA handles distribution. Before 2011, the digits had meaning tied to your location and issuance order, but now they're randomized to prevent fraud. No numbers get reused, though rare duplicates have happened in the past. You should know that scammers target SSNs, so report any issues to the Federal Trade Commission right away.
Components of an SSN
Breaking it down, an SSN has three parts. The first three digits are the area number, which used to indicate the state of issuance—lower numbers for the East Coast, higher for the West—but since 1972, it's based on your application's zip code. The middle two are the group number, ranging from 01 to 99, originally linked to batches of 10,000 numbers at post offices. The last four form the serial number, running from 0001 to 9999 in each group, with 0000 never used. There are exceptions, like numbers 700-728 for old railroad workers or 586 for certain Pacific territories, and 666 is off-limits entirely.
Timeline of SSNs
The SSN story starts in 1935 when President Roosevelt signed the Social Security Act to aid Americans post-Great Depression, focusing on retirement support based on lifetime earnings. By 1936, the nine-digit system was in place for record-keeping. Key developments include federal agencies mandating SSNs in 1943, the IRS using them for taxes in 1962, banks requiring them for accounts in 1970, and their addition to interest-bearing accounts in 1983. They appeared on driver's licenses in 1996 but were removed by 1999, and laws eased SSN mandates in 2008. Randomization began in 2011 to enhance security.
Why You Need an SSN
You need an SSN because it's tied to your future benefits— it tracks your earnings and work years to calculate retirement, disability, or health benefits. Employers use it when reporting your wages to the IRS and for state taxes. Beyond that, it's essential for opening bank accounts, applying for federal loans, getting unemployment, filing taxes, obtaining a driver's license, getting a passport, or enrolling in Medicare. Without it, many basic financial and governmental processes grind to a halt.
How to Get an SSN
To get your SSN, fill out Form SS-5 from the SSA and provide proof of age, identity, and U.S. citizenship or immigration status—there's no fee involved. You can apply for an original card, replacement, or corrections. In rare cases, you might qualify for a new number if yours is compromised. Expect the card to arrive in two to four weeks after submission.
SSNs and Identity Theft
SSNs are prime targets for identity theft since they lack biometrics and rely on documents for verification. Thieves can use yours to open credit lines, steal benefits, or commit fraud. If yours is stolen, act fast: alert credit bureaus like Experian, TransUnion, and Equifax to add a fraud alert, contact the SSA, file a police report, and monitor your accounts. You can check for misuse by reviewing credit reports, verifying income with the SSA, or requesting IRS transcripts. Remember, someone with your SSN could impersonate you for jobs, medical care, or tax refunds—protect it fiercely.

The Bottom Line
