The United States Postal Service began offering Adult Signature Required in 2011 to ensure that sensitive or important shipments ended up in responsible hands.

With that, Adult Signature Required goes beyond just ensuring that necessary packages aren’t sitting out in the open, unattended on porches or stoops.

With a signature, it’s an extra layer of security that puts the parcel directly in the hands of not just any resident of a home but a 21-year-old adult.

How Do You Know If USPS Requires An Adult Signature?

That said, the easiest way to find this information is to check your USPS Tracking page.

Therefore, the Tracking page will prominently notify you if an adult signature is required to complete the delivery.

Will USPS Leave The Package Without Adult Signature?

As mail is federally protected property, the likelihood that a USPS mail carrier would leave a package that requires an adult signature without obtaining said signature is minuscule.

However, mail carriers are human, too, and mistakes do happen (never say never).

So, if you have evidence that a package was left without obtaining the required adult signature, take your grievance to your delivering Post Office.

What Is The Difference Between USPS Adult Signature And Signature Confirmation?

USPS Adult Signature Required differs from Signature Confirmation in that the person giving the signature must be 21 years of age or older.

With that, Signature Confirmation similarly ensures that the mailpiece in question has been put into someone’s hands, but that person can be any reasonably aged resident.

So, while your 12-year-old could sign for a Signature Confirmation delivery, they could not sign for an Adult Signature delivery.

In fact, despite attaining legal adulthood in the U.S., even residents ages 18 to 20 could not sign for Adult Signature packages.

What Is The Difference Between USPS Adult Signature And Adult Signature Restricted Delivery?

This is where the terms get even trickier, but the difference between these two services is important to note.

So, Adult Signature Required means that any resident of the home over the age of 21 can sign for the delivery.

But, Adult Signature Restricted Delivery is even more specific.

For this service, only the addressee (the name on the mailpiece) can sign, and they must be 21 years of age or older.

However, the mail carrier might let the ID check slide for Adult Signature Required when the person answering the door is clearly in their 40s or 50s.

But, they’re most certainly not going to skip the ID check for Adult Signature Restricted Delivery.
