In April 2020, the United States Postal Service (USPS) modified its signature requirements for certified mail receipts. To reduce health risks, they are temporarily modifying customer signature capture procedures. While maintaining a safe, appropriate distance, employees will request the customers first initial and last name so that the employee can enter the information on the electronic screen or hard copy items such as return receipts, PS Forms 3811 and 3829. https://faq.usps.com/s/article/USPS-Coronavirus-Updates-for-Residential-Customers#mailing_shipping USPS prepared a video outlining the process: https://www.youtube.com/watch?v=2rn0LXFFMao&feature=youtu.be
Please note that the USPS signature requirement modification may impact the
sufficiency of service of process to the extent a party relies on Federal Rule
of Civil Procedure 4(e)(1) and applicable state law requirements to affect
service.
