Holiday tipping: Can you tip your mail carrier?

As the Christmas holiday quickly approaches, many may be wondering: Should you tip your mailer carrier? 

You can give your mail carrier a gift as a holiday thank-you but, as federal workers, they have certain rules to follow when it comes to receiving gifts, per the United States Postal Service. 

The bottom line: less is more.

$20 or less

Under federal regulations, you can "tip" your mail carrier with a gift that is worth $20 or less per occasion, this includes Christmas, according to the USPS.

Federal employees are not allowed to accept gifts that are worth more than $50 from any customer during one calendar year period. 

No cash

You cannot tip cash and cash equivalents, such as checks or gift cards that can be exchanged for cash, in any amount, according to the USPS.

So if you plan to show your appreciation to your mail carrier this holiday amid the ongoing pandemic that has proven extra difficult for frontline workers everywhere, consider a small gift.
