First-class and priority mail for servicemembers stationed in Afghanistan should be sent by Dec. 4 for arrival by Christmas. The deadline for parcel airlift mail is Dec. 1, and space-available mail bound for Afghanistan should be sent by tomorrow.

A chart with recommended mailing deadlines for all types of mail to various APO and FPO addresses is available at the Postal Service’s Web site at http:⁄⁄www.usps.com⁄communications⁄newsroom⁄2009⁄pr09_082.htm.

Express mail cannot be used to mail packages to Afghanistan; however priority mail is available.

Priority mail packaging products, including priority mail flat-rate boxes, can be obtained free at any post office, or online at http:⁄⁄shop.usps.com. The priority mail large flat-rate box can be used to mail to any overseas military address, no matter the weight of the box, for $11.95.

The Postal Service offers free military care kits, designed for military families sending packages overseas. To order by phone, call 800-610-8734 and ask for the military care kit. Each kit includes two ‘‘America Supports You” large priority mail flat-rate boxes, four medium-sized priority mail flat-rate boxes, six priority mail labels, a roll of priority mail tape and six customs forms with envelopes.

All packages and mail must be addressed to the individual servicemember by name, without rank.

Military overseas units are assigned an APO or FPO ZIP code, and in many cases, that ZIP code travels with the unit wherever it goes, according to Army officials.

Mail sent APO and FPO addresses may require customs forms. All mail addressed to military post offices overseas is subject to certain conditions or restrictions regarding content, preparation and handling.
