If you are leaving for Yom Tov, you may want to have your mail placed on hold while you’re away. The USPS offers this service free from 3-30 days.
It takes just a couple of minutes to sign up, which you can do by clicking here. You can sign up until 2:00 a.m the day you wish to start.
NOTE: When a hold is placed on your mail, it gets placed on the entire address, so if you’re a landlord or a tenant, be sure you both want your mail held.
