Summary
When you initially make a purchase with a merchant who uses the Square card processing system, you’ll have an option to enter an email address for a receipt.
In the future, when you use that same card with a merchant who uses Square, your email will be automatically saved from the previous purchase.
It’s not possibly to easily update the email at the time of your next purchase.
Change Email for Square Receipts
If you want to change the email address linked to your credit card, it’s necessary to click the “Manage Preferences” link at the bottom of a recent email receipt. This will take you to a page that shows all the cards associated with your phone and email.
You will probably want to save the previous purchase history and list of merchants, then delete the email address that was previously linked.
You will also want to save a screenshot of the old cards linked to your phone. These are probably old expired credit cards that you used in the past.
Unfamiliar Card Numbers
You may see some card numbers linked to your Square profile that you don’t recognized. These may be the alternate credit card number accounts that are generated by the Apple Wallet on iPhone or Watch for purchases.
If you’re curious about the alternate credit card numbers created by Apple Wallet, you can open the Wallet app on your iPhone, select a card, press the three dots menu button (top right) and scroll down to the section “Device Account Number” where you’ll see the 4-digit ending of the card.
In Wallet, the Device Account Number is described in this way:
“Apple Pay uses the Device Account Number instead of providing your credit or debit card number. This number can only be used with this iPhone.”
This may initially create some confusion because in trying to match your printed receipts with credit card accounts, you won’t initially recognized the numbers.
