You might want to think twice before abbreviating 2020 on legal documents. Executive director of the National Association of Consumer Advocates, Ira Rheingold, warns it could make it easier for scammers. The fear is that hackers could simply add numbers to the abbreviated year and turn it into any year in the 2000’s.
Example: If you were to use 1/12/20, scammers could add “08” to make it 1/12/2008. Instead they recommend using 1/12/2020 on legal documents.
This year's abbreviation is easily changeable and could be used against you.
