A customer who processes mail told me letters and packages travel quicker through the United States Postal System using ALL CAPITALS. So I tried it. I addresses a small package using all caps for the name and address. The package left Oregon on Friday and arrived in Connecticut on Monday via First Class Mail.
I can't guarantee this will work every time. Even though the above mentioned package was mailed during this pandemic, shipping times are so random since Corona virus. With more purchases are being made online, every effort to get orders to your door quicker helps.
When ordering on line, type in all caps. Many online stores, like me, copy and paste your shipping address for shipping labels. If your name and address are in all caps it just might get delivered a bit sooner. If you notice a difference, pass the info on.
As always, remember to be kind and encouraging, especially now when many are struggling under new circumstances and challenges. Warmest regards, Kim
