Certified Mail Restricted Delivery
Upon successful delivery, the USPS will request that a recipient at the delivery address signs for the letter. This signature will be provided to you directly within your OnlineCertifiedMail account, and anyone present at the delivery address is eligible to sign for the letter(s).
If you need to make sure only the specific recipient is able to sign for the letter, that service is called Restricted Delivery, which we don't currently offer through this website. However, adding Restricted Delivery as a feature is currently on our roadmap, but our development team tends to prioritize their projects based on demand.
If you have an idea of how much certified mail you will be sending out that requires Restricted Delivery feel free to let us know, as you could help us justify putting this higher up on our priority list.
