Reading a card face: holder, thru date, network and billing address
Every field on a virtual card has a job at checkout. Here is what each one is for and where people usually go wrong.
In this guide
A virtual card has no plastic, but it still has a face: a set of fields that checkout forms ask for in slightly different ways. Most failed payments on new cards come down to one field typed into the wrong box or in the wrong format. This guide goes through the fields one by one, in the order you usually meet them at checkout.
The card number
Sixteen digits for Visa and Mastercard, grouped in fours on the card so they are easier to read. Checkout forms usually accept the number with or without spaces. If a form complains, paste the digits without spaces; the copy button in My Cards copies the bare number for exactly that reason.
The first six to eight digits identify the card program that issued the card. Merchants use them to decide whether to accept the card at all, which is why two cards that look identical can be treated differently by the same store. You cannot change those digits, but knowing they exist explains a lot of otherwise puzzling refusals.
The last four digits are the part you will quote most often: to support, in your own records, and when a merchant asks you to confirm which card is on file. They are safe to share. The full number is not.
The network logo
The logo in the corner tells merchants which card network carries the payment. Most online stores accept the major networks, but a few have preferences, and some regional services only take one. If a checkout asks you to pick a card type from a menu, choose the one shown on the card face rather than guessing from the first digit.
The holder name
Many checkout forms have a "name on card" field. Copy the holder name exactly as it appears in My Cards, including its capitalization if the form is fussy. Some merchants compare this name with the name on your account with them; most do not check it at all. If you requested a specific name when ordering, that name is what the card carries. Our guide to choosing the name on your card explains when it matters.
The thru date
Labelled "thru" or "valid thru" on the card, this is the expiry month and year, written as MM/YY. Forms ask for it in three common ways:
- One field for MM/YY, typed as "08/29".
- Two dropdowns, one for the month and one for the year, where the year often appears in full as 2029.
- Two separate text fields, where the year may be two digits or four, depending on the form.
Getting the month and year the wrong way round is a surprisingly common mistake. The card stops working after the last day of the month shown, so the date also tells you how long the card can carry subscriptions. What happens at expiry explains the rest.
The CVV
Three digits (four on some networks) used to prove you have the card details in front of you. Merchants are not allowed to store it after a payment, which is why some services ask for it again when you add the card to a new device. In My Cards the CVV is hidden with the full number and only appears after you confirm with a fresh authenticator code. If a form rejects the CVV, check that you have not copied the expiry date or the last four digits into that field by mistake.
The billing address
This field causes more declines than any other. Each card comes with a billing address shown in My Cards, and that is the address the card program knows. When a checkout asks for a billing address, use that one, not your home or delivery address. Many stores let you enter a separate shipping address for delivery; that field can be anything.
Address checks usually compare only the house number and the postal code, so the important parts are those two items typed exactly. Spell out the rest sensibly, choose the matching country from the list, and leave optional fields empty rather than inventing data. If a payment still fails, the step-by-step method in fixing an address mismatch decline usually solves it.
A field-by-field checklist
| Checkout field | Take it from | Common slip |
|---|---|---|
| Card number | Copy button in My Cards | Pasting a masked number |
| Name on card | Holder name | Using your account display name |
| Expiry | Thru date | Month and year swapped |
| Security code | CVV after the code check | Typing it after it has hidden again |
| Billing address | Card's billing address | Entering the delivery address |
Once you have entered these five fields correctly for one merchant, the next checkout takes seconds. If you are still deciding what each card should pay for, start with planning your first few cards, and see the pricing page for what each card costs.
Quick answers
Is it safe to share the last four digits?
Yes. They identify a card without revealing it. Share them with support when asking about a specific card; never share the full number or CVV.
Why does a checkout reject a correct number?
Often the merchant does not accept that card type, or a browser extension changed the field. Try once more in a clean browser window before contacting support.
Can I change the billing address on a card?
No. The address belongs to the card program. Use it exactly as shown for every checkout.
