In the [[United States]], a '''Social Security number''' ('''SSN''') is a nine-digit number issued to [[United States nationality law|U.S. citizens]], [[Permanent residence (United States)|permanent residents]], and temporary (working) residents under section 205(c)(2) of the [[Social Security Act]], codified as {{uscsub|42|405|c|2}}.

== History ==
Social Security numbers were first issued by the Social Security Administration in November
On November 24, 1936, 1,074 of the nation's 45,000 post offices were designated "typing centers" to type up Social Security cards that were then sent to Washington, D.C. On December 1, 1936, as part of the publicity campaign for the new program, Joseph L. Fay of the Social Security Administration selected a record from the top of the first stack of 1,000 records and announced that the first Social Security number in history was assigned to John David Sweeney, Jr.
Before 1986, people often did not obtain a Social Security number until the age of about 14,<ref>{{cite journal |access-date=October 19, 2018 |title=Social Security Numbers Issued: A 20-Year Review |url=https://www.ssa.gov/policy/docs/ssb/v56n1/v56n1p83.pdf |journal=Social Security Journal |volume=56 |last1=Long |first1=Wayne S. |date=Spring 1993 |issue=1 |page=82}}</ref> since the numbers were used for income tracking purposes, and those under that age seldom had substantial income.<ref>{{cite journal |access-date=October 19, 2018 |doi=10.1002/sim.4780121805 |pmid=8248662 |title=A strategy for assembling samples of adult twin pairs in the United States |volume=12 |last1=Goldberg |date=October 17, 1993 |first1=Jack |issue=18 |pages=1693–1702 |url=https://www.academia.edu/11871886 |journal=Statistics in Medicine}}</ref> The [[Tax Reform Act of 1986]] required parents to list Social Security numbers for each dependent over the age of 5 for whom the parent wanted to claim a [[tax deduction]].<ref>{{cite web |access-date=October 19, 2018 |publisher=United States Social Security Administration |title=Tax Reform Act of 1986 |url=https://www.ssa.gov/history/ssn/reagantax.html |work=Social Security History}}</ref> Before this act, parents claiming tax deductions were simply trusted not to lie about the number of children they supported.

== Purpose and use ==
The original purpose of this number was to track individuals' accounts within the Social Security program. It has since come to be used as an identifier for individuals within the United States, although rare errors occur where duplicates do exist. A few duplications did occur when prenumbered cards were sent out to regional SSA offices and (originally) post offices.{{Citation needed|date=October 2023}}

== Types of Social Security cards ==
# persons of natural birth within the territorial boundaries of any one of the member States of the United States of America;
# persons who become U.S. citizens by oath, or birth within the exclusive legislative or territorial jurisdiction of the U.S. government;
# persons who become U.S. permanent residents;
# persons with certain restrictions.
There are two restricted types of Social Security cards:
* One reads "not valid for employment." Such cards cannot be used as proof of work authorization, and are not acceptable as a List C document on the [[Form I-9|I-9 form]].
* The other reads "valid for work only with [[United States Department of Homeland Security|DHS]] authorization", or the older, "valid for work only with [[Immigration and Naturalization Service|INS]] authorization." These cards are issued to people who have temporary work authorization in the U.S. from the [[United States Department of Homeland Security|Department of Homeland Security]]<ref>{{Cite web |title=Government office - Social Services Departments by state in united states |url=https://www.governmentoffice.us/social-services-departments |access-date=2022-12-27 |website=Government Office |language=en}}</ref> -- the nation's border agency. They can satisfy the I-9 requirement, if they are accompanied by a work authorization card.
The cards commonly display the cardholder's name and number.
Note: As of 2025, individuals must request their SSN in person at a Social Security Administration office, even if they applied for one through USCIS forms like I-765 or N-400. Automatic issuance (Enumeration Beyond Entry) is no longer supported.<ref>{{Cite web |title=SSN Crisis Hits Legal Immigrants in the U.S. {{!}} Investor Visa & Green Card Holders Affected |url=https://www.yildiz.law/en/blog/ssn-crisis-investor-visa-green-card |access-date=2025-07-04 |website=Yildiz Law |language=en-US}}</ref>
In 2004 Congress passed The Intelligence Reform and Terrorism Prevention Act; parts of which mandated that the Social Security Administration redesign the SSN card to prevent forgery. From April 2006 through August 2007, the SSA and [[United States Government Publishing Office|Government Printing Office]] (GPO) employees were assigned to redesign the Social Security number card to the specifications of the Interagency Task Force created by the commissioner of Social Security in consultation with the secretary of Homeland Security.
The new SSN card design utilizes both covert and overt security features created by the SSA and GPO design teams.
== Suspension of the Enumeration Beyond Entry (EBE) Program ==
In March 2025, the Social Security Administration (SSA) quietly suspended the [[Enumeration Beyond Entry program|Enumeration Beyond Entry (EBE) program]], which previously enabled automatic issuance of SSNs to applicants for work authorization (Form I-765) or naturalization (Form N-400). Under EBE, applicants would receive their SSNs via mail without needing to visit SSA offices.
With this suspension, individuals must now schedule in-person appointments at SSA offices to obtain an SSN—even if they selected the SSN option on USCIS forms. This change impacts new green card holders, work permit recipients, and naturalized citizens who cannot legally work, open bank accounts, or obtain state IDs without an SSN.
SSA estimated that the automatic issuance cost was approximately '''$8''', while the current in-person issuance process now costs '''$55.80''' per request. Staffing cuts of 12% and the closure of 47 SSA offices have exacerbated appointment backlogs, affecting over 3.24 million I-765 applicants in 2024 alone.
Individuals experiencing delays are advised to document the impact on employment, housing, or financial access and consult immigration counsel as necessary. <ref>{{Cite web |title=SSN Crisis Hits Legal Immigrants in the U.S. {{!}} Investor Visa & Green Card Holders Affected |url=https://www.yildiz.law/en/blog/ssn-crisis-investor-visa-green-card |access-date=2025-07-04 |website=Yildiz Law |language=en-US}}</ref>
== Identity theft ==
Many citizens and [[privacy]] advocates are concerned about the [[data broker|disclosure and processing]] of Social Security numbers.<ref>{{Cite web| title=Fair Credit Reporting Act | url=https://www.ftc.gov/system/files/ftc_gov/pdf/fcra-may2023-508.pdf | archive-url=https://web.archive.org/web/20230517222643/https://www.ftc.gov/system/files/ftc_gov/pdf/fcra-may2023-508.pdf | archive-date=2023-05-17}}</ref> Furthermore, researchers at [[Carnegie Mellon University]] have demonstrated an algorithm that uses publicly available personal information to reconstruct a given SSN.<ref>{{cite web |url=https://arstechnica.com/science/2009/07/social-insecurity-numbers-open-to-hacking/ |first=John |last=Timmer |publisher=Ars Technica |date=July 17, 2009 |access-date=October 19, 2018 |title=New algorithm guesses SSNs using date and place of birth}}</ref>
The SSN is frequently used by those involved in [[identity theft]]. This is because it is interconnected with many other forms of identification and people asking for it treat it as an [[authentication|authenticator]]. Financial institutions generally require an SSN to set up [[bank account]]s, [[credit card]]s, and [[Loan|loans]]—partly because they assume that no one except the person it was issued to knows it.
Line 61 ⟶ 90:
Exacerbating the problem of using the Social Security number as an identifier is the fact that the Social Security card contains no [[Biometrics|biometric]] identifiers of any sort, making it essentially impossible to tell whether a person using a certain SSN truly belongs to someone without relying on other documentation (which may itself have been falsely procured through use of the fraudulent SSN). Congress has proposed federal laws that restrict the use of SSNs for identification and bans their use for a number of commercial purposes—e.g., rental applications.<ref>{{cite web |access-date=October 19, 2018 |publisher=News.cnet.com |last=Broache |title=Congress may slap restrictions on SSN use - CNET News |url=http://news.cnet.com/Congress+may+slap+restrictions+on+SSN+use/2100-7348_3-6071441.html?tag=nefd.top |url-status=dead |archive-url=https://archive.today/20120711052547/http://news.cnet.com/Congress-may-slap-restrictions-on-SSN-use/2100-7348_3-6071441.html |archive-date=2012-07-11 |first=Anne}}</ref>
The [[Internal Revenue Service]] (IRS) offers alternatives to SSNs in some places where providing untrusted parties with identification numbers is essential. Tax return preparers must obtain and use a [[Preparer Tax Identification Number]] (PTIN) to include on their client's tax returns (as part of signature requirements).<ref>{{Cite web|title=PTIN Requirements for Tax Return Preparers {{!}} Internal Revenue Service|url=https://www.irs.gov/tax-professionals/ptin-requirements-for-tax-return-preparers|access-date=2021-02-20|website=www.irs.gov|language=en}}</ref> Day care services have tax benefits, and even a sole proprietor should give parents an
The Social Security Administration has suggested that, if asked to provide their Social Security number, a citizen should ask which law requires its use.<ref name="howcaniprotect"/> In accordance with §7213 of the [[9/11 Commission Implementation Act of 2004]] and {{USCFR|20|422|103|(e)(2)}}, the number of replacement Social Security cards per person is generally limited to three per calendar year and ten in a lifetime.<ref name="howcaniprotect">{{cite web |url=https://www.ssa.gov/pubs/EN-05-10002.
Identity confusion has also occurred because of the use of local Social Security numbers by the Federated States of Micronesia, the Republic of the Marshall Islands, and the Republic of Palau, whose numbers overlap with those of residents of New Hampshire and Maine.<ref>{{cite news |access-date=October 19, 2018 |publisher=The Plain Dealer |first=Bill |last=Meyer |title=How many Americans' Social Security numbers were officially duplicated for Pacific islanders? |url=https://www.cleveland.com/nation/index.ssf/2009/08/how_many_americans_social_secu.html |date=August 17, 2009}}</ref>

Because [[Individual Taxpayer Identification Number]]s (ITINs) are issued by the IRS, they are not affected by this SSA change.
=== Previous structure ===
Before randomization, the first three digits, the [[#List of Social Security area numbers|area numbers]], were assigned by geographical region. Before 1973, cards were issued in local Social Security offices around the country, and the area number represented the office that issued the card. This did not have to be in the area where the applicant lived, because one could apply for a card in any Social Security office. Beginning in 1973, when the SSA began assigning SSNs and issuing cards centrally from [[Baltimore]], the area number was assigned according to the [[ZIP Code]] of the mailing address on the application for the original Social Security card. The applicant's mailing address did not have to be the same as their place of residence, so the area number did not necessarily represent the applicant's state of residence, regardless of whether the card was issued before or after 1973.
Generally, numbers were assigned beginning in the [[Northeastern United States|northeast]] and moving south and west, so that people applying from addresses on the east coast had the lowest numbers and those on the west coast had the highest numbers. As the areas assigned to a locality were exhausted, new areas from the pool were assigned, so some states had noncontiguous groups of numbers.
The middle two digits, ''group number'', range from 01 to 99. Even before SSN randomization, the group numbers were not assigned consecutively in an area. Instead, for administrative reasons, group numbers were issued in the following order:<ref>{{cite web |url=https://www.ssa.gov/history/ssn/geocard.html |publisher=SocialSecurity.gov |access-date=October 19, 2018 |title=The SSN Numbering Scheme}}</ref>
# odd numbers from 01 through 09
Line 104 ⟶ 134:
# odd numbers from 11 through 99
The last four digits,
=== Valid SSNs ===
Some special numbers are never allocated:

Unlike many similar numbers, Social Security numbers have no [[check digit]]
===Exhaustion and re-use===
The Social Security Administration does not reuse Social Security numbers. It has issued over 450 million since the start of the program,

Some SSNs used in advertising have rendered those numbers invalid. One famous instance of this occurred in 1938 when the [[E. H. Ferree Company]] in [[Lockport (city), New York|Lockport, New York]], decided to promote its product by showing how a Social Security card would fit into its wallets. A sample card, used for display purposes, was placed in each wallet, which was sold by [[F.W. Woolworth Company|Woolworth]] and other department stores across the country; the wallet manufacturer's vice president and treasurer Douglas Patterson used the actual SSN of his secretary, Hilda Schrader Whitcher.
Even though the card was printed in red (the real card is printed in blue) and had "specimen" printed across the front, many people used Whitcher's SSN as their own. The Social Security Administration's account of the incident also claims that the fake card was half the size of a real card, despite a miniature card being useless for its purpose and despite
