PayPal guest checkout not working for shoppers

Your own test is almost never a guest test. Your browser may already hold a PayPal session, so the checkout offers you the account you know, and the card route you need never appears. A shopper with no account sees a different window: a login box with a sign-up link, or a card form with a field the page rejects. The gap is invisible from inside, because the one browser you test with already has the answer. Only a signed-out window with a new shopper shows what the guest actually gets.

• Does a signed-out shopper see a way to pay by card, next to the PayPal login?
• Does the card form accept a billing postal code in the shopper's country?
• Does a required billing field stop the shopper before the card step?
• Does the checkout show the same currency and total that the cart showed?

Your PayPal test runs through the browser you use every day. That browser can hold a PayPal session, a saved address and a payment choice from last time, and checkout may skip the steps a guest has to take. You also already know how the page should look, so you read what you expect instead of what is there. The guest sees the page for the first time, with nothing remembered, and the route that matters most is the one you never click.

Test as a guest from a private window, signed out of PayPal, with a shopper name and address you have not used before. Start from the product page, not from your saved cart. Then write down every option the checkout shows, in order, because the first screen is the one a guest decides on. Keep that list before you change anything.

Checkout flow testing

PayPal decides which options a shopper sees. Your account settings are one input, and the shopper's country and the currency of the order are others. PayPal may show only the account route to a shopper in some countries, even on a store that sells there. A currency the account does not support can change the page too. Those rules belong to PayPal and to your account settings, not to your page, so the test cannot change them. It can show you the result for each country and currency you sell in.

Once a guest reaches the card form, the form asks for a billing address, and that address is checked. A postal code in a format the form does not expect, a region field that is required for one country and not another, or a country list that does not match the shipping list can each reject a valid address. The guest sees a red message under a field and cannot tell which rule refused them. Check the form with a billing address in a country you ship to, and read the message beside each field.

Run the same guest path in two countries you sell to, with the same product and a different billing address. If one country passes and the other stops at a field, the cause is the address rule, not the card. If both stop on the same field, look at which rule that field enforces before you touch the PayPal settings.

The guest route can disappear after a change you did not make to the page: a PayPal account setting, a new currency in the store, or a new shipping country that changes the address form. Rerun a signed-out guest from each country you sell to after every one of those changes. You see the option that went missing on the step where it went missing.
