INDIANAPOLIS — Retail services at Post Offices throughout Indiana will be closed on Monday in recognition of Columbus Day. Regularly scheduled mail delivery, PO Box and caller services will also be suspended for the holiday.

 Customers requiring postal services can use the Self- Service Kiosk available at select Post Offices. The ATM-like kiosk, which accepts debit and credit cards only, can handle 80% of the transactions conducted at the retail counter such as buying stamps, mailing a parcel or shipping an urgent letter or package by Express or Priority Mail.  Access to a SSK is available 24-hours a-day, seven-days-a-week. Go to usps.com, Find Locations, put in your ZIP Code and you’ll find a nearby Post Office that has a kiosk.

 Commercial customers are asked to check with their Bulk Mail Acceptance Unit for hours of operation. To obtain the phone number of a specific Post Office, customers may call 1-800-ASK-USPS.

 Mail will be delivered as scheduled on Tuesday. Post Offices also will resume regularly scheduled retail lobby hours Tuesday.
