What information do I need to provide to buy

To complete the purchase, the checkout asks for some details. They are used to issue the purchase in your name, send access or delivery, and meet security requirements. The checkout validates each field before letting you pay, so it is worth filling everything in carefully.

Personal details (always required)

• Full name — must have at least 3 characters. A name that is too short is rejected.
• Email — must be a valid email (with ”@” and a domain). This is the email where the confirmation and product access are usually sent, so use an address you can actually check.
• Document / Tax ID — for purchases in Brazil, the tax document is required and must be valid: 11 digits for an individual (CPF) or 14 for a company (CNPJ). An invalid document produces an error and blocks the payment.

Phone number

The phone number is required on most purchases in Brazil. When required, it must be a valid number (10 or 11 digits, with area code). In some flows the field may be optional, but if you fill it in, the number must be correct.

When paying with PayPal, the phone number becomes required, even if it would be optional with other payment methods.

Address

This depends on the type of product:

• Physical product (that will be shipped): the address is required. You need to fill in the ZIP/postal code, street, number, neighborhood, city, and state/region. All are validated — an incomplete ZIP code or an invalid state, for example, produce an error.
• Digital product (course, e-book, online access): usually no address is needed. If the field appears and you start filling it in, then the entered data is validated.

If an error message appears

When a field is missing or incorrect, the checkout shows a message pointing to the field (for example, “Please enter a valid email”, “Please enter a valid document”, or the name of the missing address field). Fix the item indicated and try to pay again.

Filling everything in correctly the first time avoids declines and speeds up the release of your product.
