USP’s tracking number structure 

USPS shipping labels have a specific structure, referred to as a tracking number. These numbers contain 10 to 22 digits and two to eight symbols, indicating the shipping service and country of origin. Priority Mail labels are assigned a letter, while other types of mail are given a digit. Here are some tips to remember USPS tracking numbers. We’ll also look at some other important aspects of tracking a package. 

USPS tracking numbers are different from those for domestic mail and packages. Domestic USPS mail and packages start with a series of numbers (like 9400 or 1ZZZZZZZ), whereas international packages begin with a letter combination. These numbers will also indicate whether or not the package is fully trackable. If you have trouble identifying a package’s USPS tracking number, consult a post office website. 

Verification process 

A mailing service may request that you verify the email address on your list. There are several ways to do this. One option is to verify by using a service called Quick Email Verification. This process involves seven separate validation steps to identify Safe-to-Send email addresses and place them in a list ready for mailing. This process can be done for both domestic and international B2C emails. Verification is done using two different APIs: a real-time API, which checks new submissions on a form, and a bulk verification API, which processes a full batch of uploaded email addresses. 


There are many different ways to track your mail, including through the post office. USPS, UPS, and FedEx all offer tracking of packages and letters, but they each charge a different price. The Post Office offers signature-required delivery confirmation for $3.15. You can also choose to receive daily emails about your mail. This service is more for the convenience of the sender than for the recipient. However, if you’re unsure if your mail is safe, you can sign up for a signature-required delivery confirmation service.
