Businesses and individuals who use Fedex shipping services on a frequent basis will usually benefit from having a Fedex account. The benefits of a Fedex account include discounts on shipping rates and more advanced reporting tools. It also allows you to ship packages using your Fedex account number, to be billed at a later date. Using a Fedex account number to ship packages is easy to do.

Sign up for a Fedex account number. A Fedex account can be obtained online at the Fedex website (fedex.com) or by calling 1-800-GO-FEDEX (1-800-463-3339).

Obtain a blank Fedex airbill. An airbill is the form that is filled out to provide Fedex with the information for both sender and receiver. Get an airbill from any Fedex shipping location, including drop boxes or from a Fedex delivery driver.

Fill out the airbill. Use a black or blue ink pen to fill out the name, address and telephone number for the shipper and receiver. Check the box marked “Sender” in section 7 of the airbill which contains the billing information. Clearly write your Fedex account number in the space marked “Fedex Account No.” Leave the line for credit card information blank.

Affix the airbill to your Fedex package or envelop. Place the package in a Fedex drop box, deliver it to an authorized shipping center or give it to any Fedex delivery driver. You will be billed automatically according to your billing schedule.
