NEW: Earn bonus points adding someone to your Marriott, Nectar or ARCC Amex card

Links on Head for Points may pay us an affiliate commission. A list of partners is here.

Adding a supplementary cardholder to your American Express card has two key benefits:

you earn points, and trigger sign-up bonuses, more quickly when two people are carrying a card

you receive a second batch of cardholder cashback offers, as long as the supplementary card is registered online

On most of the American Express cards, you would also receive bonus points for adding a supplementary cardholder.

This is NOT usually a benefit for holders of the Marriott, Nectar, Amex Rewards Credit Card or Harrods American Express card. However, for a limited period, it is – see the Amex website here.

Until 31st July, you will receive:

3,000 Marriott Bonvoy points when you add your first supplementary card to your Marriott Bonvoy American Express

3,000 Nectar points when you add your first supplementary card to your Nectar American Express

2,000 Membership Rewards points when you add your first supplementary card to your American Express Rewards Card or Amex Green card

1,000 Harrods Rewards points when you add your first supplementary card to your Harrods American Express card

This are valuable incentives, given that the supplementary card is free:

3,000 Marriott Bonvoy points are worth £15 using HfP valuations

3,000 Nectar points are worth 1,875 Avios, which are worth £18.75 using HfP valuations (or use them for £15 of Sainsbury’s shopping)

2,000 Membership Rewards points are worth 2,000 Avios (£20 on our valuations) if you choose to use them for that

1,000 Harrods Rewards points are worth £10

The points will post very quickly. You should see them within 3-4 days of applying for the supplementary card. There is no requirement to spend a particular amount on the supplementary card.

How to apply

American Express has a special website for adding supplementary cards which you can find here.

This page also contains the standard supplementary card offers for the core Amex cards.

You cannot apply for a supplementary American Express Rewards Credit Card via that page. You need to log into your online Amex account and follow the link on your statement page, which may be under the ‘Offers’ section.

These special offers for adding supplementary American Express cards will run until 31st July.
