Do you know who delivers your mail? July 1st is National Postal Worker Day, which means it’s the perfect time to show some appreciation to your mail carrier. However, most Americans do not actually know who delivers their mail, as just 24% say they know their mail carrier’s name (excluding ‘other/does not apply’). 

This familiarity is highest among young adults aged 18–29, with 32% reporting they know their carrier by name. Financial status also plays a role: Americans earning over $50,000 annually are notably more likely to know their mail carrier than those making less.

Of course, age and income are just the beginning of the story. A closer look at the data reveals that knowing your mail carrier’s name is linked to a range of other unique daily behaviors. Here’s what the data show about those who know their mail carrier’s name: 

Grocery Store Preferences: Those who know their mail carrier’s name are nearly twice as likely to purchase groceries at stores such as Whole Foods, Trader Joe’s, and Costco, than those who do not (15% vs 8%). 

E-Sports Fandom: While 22% of those who know their mail carrier’s name watch e-sports events, just 12% of those who do not know their mail carrier’s name say the same. 

Bedtime: When it comes to bedtimes, those who know their mail carrier’s name are six percentage points more likely to go to bed between 10pm and 11pm than those who do not know the name of their mail carrier (35% vs 29%). 

Spice Engjoyment: Those who know the name of their mail carrier like to turn up the heat in the kitchen, as this demographic is five percentage points more likely to favor spicy food than those who don’t know their mail carrier’s name (69% vs 64%). 

Movie Attendance: While 16% of those who know their mail carrier’s name go to the movies once a month or more, just 9% of those who do not know their mail carrier’s name say the same.
