As if it’s not hard enough to remember to write 2020 and not 2019 on your checks, now authorities are warning about a new scam specific to this year.

If you abbreviate 2020 as ’20 on legal documents (e.g. checks and contracts), scammers can easily alter the date, leaving individuals vulnerable to fraud.

For example, 1/10/20 can easily be turned into 1/10/2021 simply by adding two numbers.

Here is why this may cause a problem.

Let’s say you signed a contract to pay a debt beginning on 1/10/20. Theoretically, that could be turned into 1/10/2019, allowing the scammer to attempt to collect a past debt.

Another example is related to checks and the advent of mobile banking. If you write a check for 1/10/20 and that check is deposited through a mobile app, the depositor remains in possession of the check. They could, in theory, alter the date to 1/10/2021 and attempt to redeposit the check next year.

Some people are calling this warning “fear mongering” but police departments, financial advisors, auditors, and consumer advocates all agree on this one. While it’s certainly true that this scam could have occurred last year, the fraudulent act likely would have been more easily detected if a contract was altered from 1/10/19 to 1/10/1999. 

Protecting yourself from this scam is easy: Write the year out completely – 2020 – on all legal documents.
