What is the primary purpose of Ancillary Service Endorsements?

The primary purpose of Ancillary Service Endorsements is to provide additional services or options for mailpieces. These endorsements are added to mail items to inform postal workers and recipients about specific handling instructions, service requests, or delivery options that are relevant to that particular mailpiece.

For example, a mailpiece might require a signature upon delivery, may need to be returned to the sender if undeliverable, or could be marked for specific forwarding instructions. These endorsements enhance the versatility and effectiveness of mailing services by allowing senders to specify how they would like their items handled, thus ensuring that the mailpieces are processed correctly and meet the sender's needs.

Using these endorsements can help in managing the delivery process more effectively, giving senders and recipients added peace of mind when sending important documents or packages. This additional functionality is precisely what makes Ancillary Service Endorsements a valuable component of mailing services, setting them apart from basic mailing options.
