Since 2010, foreign nationals are no longer issued with identity cards, although they are assigned a number in the format X-0000000 - A (again, 0 is a digit, A is a checksum letter, and X is a letter, generally X but lately also Y), called an NIE Number (Número de Identificación de Extranjeros, Foreigner's Identity Number). The numbers are used as identification for almost all purposes . This is required for all transactions related with tax authority . </P> <P> Foreign nationals are required to use their passports together with the document containing their NIE number </P> <P> In Sweden a Personal Identity Number (Swedish: personnummer) is used in dealings with public agencies, from health care to the tax authorities . It is also used as a customer number in banks and insurance companies . It is written on all approved identity documents, making the risk of mixing up people low . The number uses ten digits, YYMMDD - NNGC . The first six give the birth date in YYMMDD format . Digits seven to nine (NNG) are used to make the number unique, where digit nine (G) is odd for men and even for women . For numbers issued before 1990, the seventh and eighth digit identify the county of birth or foreign - born people, but privacy - related criticism caused this system to be abandoned for new numbers . </P>
