Are USPS "Stamps" Still Allowed On US Mail?

james's: Correct, but if you just using stamps only and are mailing something under 10oz with First Class Package or Priority Mail, does the USPS offer a tracking number? From the OP's first post, it sounds like they do and if so, how does one obtain one?

I send first class packages with stamps all of the time and use Label 400 on the package. Label 400 is the alternative to digital tracking number and is free with first class package and higher rate classes when using stamps. There is still the 10 ounce rule on packages with stamps (formally 13 ounce uni-bomber rule) and now packages which are thicker than half an inch with stamps must be handed to a clerk (also adopted as a result of the bombs in small packages in the Austin area a couple of years ago).

The mailer retains the narrow strip at the bottom.
