We have released a change when printing USPS international shipping label that uses the CP72 customs form. This applies to Stamps.com and Express1.
These labels are used for USPS Priority Mail International (excluding flat rate envelope and small flat rate box), and USPS Express International.
Teapplix use to print 3 copies. Now we print 4 copies. The 4th copy should be kept by you for proof of mailing.
