What is the difference between First Class Mail and Standard Rate Mail (Bulk Rate)?
First Class Mail is your best choice for time-sensitive materials. First Class Mail is generally delivered in 3-5 days nationally and 1-3 days in California and the Southwest. Standard Mail (also known as U.S. Bulk rate) offers lower postage rates but with a longer delivery time. You can expect delivery in 10-14 days nationally and 4-6 days in California and the Southwest U.S. Additionally, First Class delivery is consistent throughout the year while Bulk rate can take considerably longer at peak mailing periods such as the holidays.
