What is a Personal Identification Number, or PIN?
Your Personal Identification Number, or PIN, is a four-digit number (0-9) selected by you. It will ensure that no one but you will have access to your account information or transactions via our web site and the WorldPerks Automated Information Line. You will need your PIN each time you wish to access your WorldPerks account information so it's a good idea to write it down. For your protection, always store your WorldPerks number separate from your PIN.
How do I request a PIN? Your PIN can be any four-digit number that is easy for you to remember, except 0000. To create your PIN, visit
www.nwa.com or call the WorldPerks Automated Information Line at 1-800-327-2881. A PIN cannot be created by a Northwest representative. When creating a PIN, you will be required to provide your Zip/Postal code if it is on file with WorldPerks. Some areas in the Asia Pacific region either do not have postal codes or have recently changed postal codes. To see what address information is on file with WorldPerks, simply check your last mileage summary or mailing from WorldPerks or contact your local WorldPerks Service Center.
What if I forget my PIN? If you forget your PIN, you may request a PIN reminder
by visiting www.nwa.com or by calling the WorldPerks Automated Information Line at 1-800-327-2881. Your PIN reminder will be sent by postal mail to your address on file with WorldPerks.
If I save my PIN on my PC, for how long will it be saved? The PIN can be saved on your personal computer for one year.
This means you will not be asked for your PIN on subsequent visits to nwa.com.
Each time you return to nwa.com and elect to save or continue to save your PIN on your PC, your one year period begins again. After one year you will be required to re-enter your PIN.
If you use a PC other than your own personal computer to access your account,
we recommend you log out of WorldPerks when leaving that computer.
Not logging out will enable anyone with access to that computer access to your WorldPerks information.
How can another user log in if I have chosen to have my PC remember my PIN? To clear your PIN from your PC and allow another user to log in, you must first log out of your nwa.com WorldPerks session. Go to the Mileage Balance page and click on Log Out. Once you have logged out, a new user can enter their WorldPerks number and PIN to begin their own nwa.com WorldPerks session. If you are using someone else's PC, first make sure they are logged out and then enter your WorldPerks number and PIN.
How do I request mileage that has not been added to my account? To ensure that retroactive miles are properly credited to your account, you must provide the original,
13-digit ticket number from your Northwest-operated flight.
Northwest Airlines will no longer issue retroactive credit based
on a boarding pass alone. If you purchased your ticket using a credit card, you'll find your ticket number
on the credit card statement or receipt. Otherwise, your ticket number can be found on your Trip Summary and Receipt or your paper ticket. A Northwest ticket number always begins with 0. Your travel professional can also provide you the number.
To request retroactive credit, visit the WorldPerks on nwa.com
and select "Mileage Request" or call 1-800-327-2881 and select option 1.
How is my Account History displayed and how many transactions can I view at once? Your Account History will be displayed based upon your flight and non-flight activity and you may view up to 15 transactions at a time.
