  • Context: A user has two Amex cards that share the same last four digits due to Amex’s scheme for additional users/replacement cards (often ending in “100n”).
  • Reference: American Express statements and its website display the last five digits, which reliably distinguish cards.
  • Ask: Have Shop Pay show the last five digits for Amex instead of four to improve card identification at checkout.

Hi there,

It turns out that I have two different Amex cards, both have the last four digits. This is a side-effect of how Amex uses those digits to indicate which additional user and which replacement card it is - everyone’s first amex, for example, usually end in 100n.

Amex’s statements and website uses the last five instead, which seems unique enough.

Can you have Shop Pay show the last five?
