GRAND RAPIDS – The United States Postal service will deliver on Sundays again this holiday season.

Following the success of the 2014 holiday season, the Postal Service will again deliver packages seven days a week in select major cities and high-volume areas beginning Nov. 29, for the four Sundays before Christmas.

They expect to deliver on average approximately five million packages every Sunday during December.

In time for the holidays, the Postal Service will offer real-time delivery notifications – meaning customers who sign up for alerts at myusps.com will receive notification within a few minutes of the delivery scan for select packages.

“Customers can count on the Postal Service and our more than 600,000 dedicated employees to deliver their holiday gifts, cards and letters,” said Megan J. Brennan, Postmaster General and CEO.

“We have been investing in our infrastructure including package sortation equipment, new delivery vehicles and scanning technology to expand our capacity, improve operating efficiency and provide real-time visibility,” she added.
