Personal Social number requirements:

• A personal number is required for registrants from Sweden. For registrants from other countries, a social security number is required.
• If the registrant provides a Swedish address but wishes to use an ID number issued by another county, the ID number MUST include the two-letter code of the issuing country in square brackets.
  For example, a passport from the Netherlands with the number 12345678 would be recorded as [NL]12345678. For residents of Sweden, do not include the country code; the acceptable format is 123456-7890 (6 digits, dash, 4 digits).
• If the registrant provides a non-Swedish address, the SSN should be without dashes, example: NL12345678 or 111122222333333
