I don’t have these charge cards, so I don’t have any personal success with this, but here’s what I know.

1. Call 1-800-297-3276 and ask to apply promo code 5721 to your account. You may have to hang-up and call back again if the customer service representative (CSR) does not apply the promo code to you account.
You could also send a message to American Express asking to add promo code 5721 to your account.
2. Add an Authorized User to your American Express charge cards. You may be able to do this in the same phone call as in step 1 above, or you may have to hang up and call card services (or get the CSR to transfer you).
Remember that adding an authorized user to your credit card means that your balance on the charge card will also be reported in the authorized user’s credit report.
You may have to provide the date of birth and social security number of the authorized user. If you don’t want to provide the social security number, you could hang up and call back later to speak with a more agreeable CSR.
Remember, you don’t have to send the authorized user the card (if you’re worried about the authorized user going on a spending spree!). The card will be mailed to your address.
You could use your children (above 16), parents, siblings, in-laws as authorized users.
3. Spend at least $1 on the authorized user’s cards. You have to spend at least $1 within 4 months on the authorized user’s charge cards to get the bonus MR points. The points should post in 6 to 8 weeks.
If you have an American Express charge card, then consider adding a few authorized users to your accounts to get a 10,000 extra MR points per user.
If you’ve already added an authorized user since January 2011 to your American Express charge cards, then call or email to ask for 10,000 bonus MR points.
You can get up to 50,000 points for EACH charge card you have with American Express, so consider adding authorized users to personal as well as business charge cards.
