What Does A Postal Service Clerk Do

Postal service workers sell postal products and collect, sort, and deliver mail. 


Postal service workers typically do the following:

  • Collect letters and parcels
  • Sort incoming letters and parcels
  • Sell stamps and other postal products
  • Get customer signatures for registered, certified, and insured mail
  • Operate various types of postal equipment
  • Distribute incoming mail from postal trucks

Postal service workers receive and process mail for delivery to homes, businesses, and post office boxes. Workers are classified based on the type of work they perform.

The following are examples of types of Postal Service workers:

Postal service mail carriers deliver mail to homes and businesses in cities, towns, and rural areas. Most travel established routes, delivering and collecting mail. Carriers cover their routes by foot, vehicle, or a combination of both. Some mail carriers collect money for postage due. Others, particularly in rural areas, sell postal products, such as stamps and money orders. All carriers must be able to answer customers’ questions about postal regulations and services and, upon request, provide change-of-address cards and other postal forms. 

Postal service clerks sell stamps, money orders, postal stationery, mailing envelopes, and boxes in post offices throughout the country. These workers register, certify, and insure mail, calculate and collect postage, and answer questions about other postal matters. They also may help sort mail.

Postal service mail sorters, processors, and processing machine operators prepare incoming and outgoing mail for distribution at post offices and mail processing centers. They load and unload postal trucks and move mail around processing centers. They also operate and adjust mail processing and sorting machinery.

Although there is no specific postsecondary education requirement to become a postal service worker, all applicants must have a good command of English.

Postal service mail carriers must be at least 18 years old. They must be U.S. citizens or have permanent resident-alien status. Males must have registered with the Selective Service when they reached age 18.

All applicants must pass a written exam that measures speed and accuracy at checking names and numbers and the ability to memorize mail distribution procedures. Jobseekers should contact the post office or mail processing center where they want to work to find out when exams are given.

When accepted, applicants must undergo a criminal background check and pass a physical exam and a drug test. Applicants also may be asked to show that they can lift and handle heavy mail sacks. Mail carriers who drive at work must have a safe driving record, and applicants must receive a passing grade on a road test.


Newly hired postal service workers receive short-term on-the-job training, usually lasting less than 1 month. Those who have a mail route may initially work alongside an experienced carrier.
