Bulk Rate Postcard Postage. Bulk mail is a way to save money on postage by doing things that the Postal Service would usually do, like sorting the mail for them and adding barcodes. This postcard size guide covers the standard postcard size, optional larger postcard sizes, paperweight for postcard thickness, and mailing costs and regulations.

You can track your international registered mail item or packet to its destination by using our online international tracking system.
There are discounts for Special Local Mail and presorted (pre-coded) business mail. Postage prices change periodically, so it's a good idea to double-check postage rates, even if you've mailed a similar-size-and-weight package before. Rates were based on the distance between sender and receiver in the early years of the nation.
