CERTIFICATE OF MAILING
Customers can purchase a certificate of mailing,
PS Form 3817, when they send unregistered letters,
letter packages, post/postal cards, printed matter
items, matter for the blind, and small packets;
uninsured parcel post; or require a duplicate of an
original certificate that pertained to a previously
mailed item. A certificate of mailing cannot be
obtained in combination with registered mail, insured
parcel post, or recorded delivery service.
