when is a social security number issued at birth
Social Security number Before 1986, people often did not obtain a Social Security number until the age of about 14,[7] since the numbers were used for income tracking purposes, and those under that age seldom had substantial income.[8] 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.[9] Before this act, parents claiming tax deductions were simply trusted not to lie about the number of children they supported. During the first year of the Tax Reform Act, this anti-fraud change resulted in seven million fewer minor dependents being claimed. The disappearance of these dependents is believed to have involved either children who never existed or tax deductions improperly claimed by non-custodial parents.[10] In 1988, the threshold was lowered to 2 years old, and in 1990, the threshold was lowered yet again to 1 year old.[11] Today, an SSN is required regardless of the child's age to receive an exemption.[citation needed] Since then, parents have often applied for Social Security numbers for their children soon after birth; today, it can be done on the application for a birth certificate.[12]
Citizenship of the United States All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.
National identification number In the United States, a Selective Service Number must be applied for by all male citizens turning age 18. An optional national identity number is the Social Security number (SSN), a nine-digit number issued to U.S. citizens, permanent residents, and temporary (working) residents. Its purpose was to identify individuals for the purposes of Social Security, but it is now also used to track individuals for taxation purposes. There is no legal requirement to have a SSN if it is not required for Social Security or taxation purposes, but in practice one is required for many other purposes, for example to open a bank account or apply for a driving license, so that nearly all U.S. citizens and permanent residents have one. The SSN has therefore become a de facto national identification number,[11] despite the fact that originally it was expressly not for this purpose[12], and in fact a valid SSN can be easily guessed, as they are issued serially[13]
Vehicle identification number VINs were first used in 1954.[1] From 1954 to 1981, there was no accepted standard for these numbers, so different manufacturers used different formats.
National Insurance number Persons from abroad who wish to work in the UK, or those to whom a number was not initially allocated as children, must apply for a number through the Department for Work and Pensions (DWP).[6] The prefixes used are typically different from those used in the normal run.[6][not in citation given]
