Sign your name in the upper-left corner of the traveler's check. You should do this to all of your traveler's checks as soon as you get them in your hand. Think of your signature as your insurance policy in case of loss or theft.
Add an additional signature to the upper-left corner of the travelers check. If you have American Express Checks for Two, your partner also needs to sign them.
Sign your name in the lower-left corner. You must do this in front of the person you're giving the travelers check to, so only do this when you're completing a transaction. The upper-left and lower-left corner signatures must match.
