A website offering free online instruction for the general public has been expanded to include more than 200 courses.
In a blog post, USPS said it is offering the courses for free to all users who are members of the USPS Learning Community.
The site, which is now in its third year, also has more than 250,000 users worldwide.
The service will include tutorials, courses, quizzes, video guides, and more.
It will be open to anyone who is enrolled in a USPS Learning community, USPS says.
“Our goal is to help make the USPS your primary source for knowledge and information, as well as the information for your next project, event, or job,” USPS says in a blog statement.
The new online courses are offered in a number of languages, including English, French, Spanish, Italian, Portuguese, and German.
They will include a variety of topics from the history of postage stamps to how to use stamps for advertising, among other topics.
USPS says it has been expanding the program for more than two years, but the company said it had not yet decided which language to expand the courses to.
A recent report by the U.S. Postal Service found that over 75 per cent of Americans do not have a formal postal service, which means they do not receive stamps, pay postage, or use stamps to mail their mail.
