For your protection, do not abbreviate 2020 on your checks and other documents!
By writing out the date as 1/7/20, scammers could easily manipulate the date by adding additional numbers, such as 1/7/2021 or 1/7/2010. The scammers could use this method to cash an old check or even establish an unpaid debt (a debt you legitimately paid, but they altered the date on the check and are asking for additional money).
Protect yourself by writing out the full year, 2020, on your checks and other legal and professional documents.
