Three things set it apart from the plugins that came before it. **1. It works in the block checkout.** WooCommerce replaced its checkout with one built on blocks. Plugins written for the old checkout simply draw nothing there: the customer reaches the payment step and there is no CPF field at all. This plugin uses the official additional checkout fields API, the same one WooCommerce itself uses, so the fields show up in both checkouts without workarounds. **2. It accepts the alphanumeric CNPJ.** Since 31 July 2026 the Brazilian federal tax authority issues CNPJ numbers that contain letters (Normative Instruction RFB 2.229/2024). The identifier still has 14 positions, but the first 12 may include letters; only the 2 final check digits remain numeric. A validator that accepts digits only will reject a legitimate company at checkout, and the sale is lost without anyone finding out why. The validation rule here was checked during development against 200,000 random numeric CNPJ numbers plus six real, publicly known ones: the new algorithm accepts everything the old one accepted, with no divergence. The plugin also ships a diagnostics page that runs a short validator battery inside your own store, so you can see the rule working on your installation. **3. You can move off the old plugin without losing data.** Stores already running _Brazilian Market on WooCommerce_ have the CPF stored in _billing_cpf, and the whole ecosystem reads it from there: invoicing software, payment gateways, themes, export spreadsheets. This plugin **writes to the same keys, in addition to the new ones. Nothing that used to work stops working when you switch. Existing customer records are imported automatically, in batches, without locking up the admin. #### Address autofill from the CEP Type the Brazilian postal code and the street, district and city fill themselves, in the block checkout and in the classic one alike. The lookup uses ViaCEP, needs no key and no account. It only writes into fields that are still empty, so it never erases something the customer typed. If the CEP is unknown, or ViaCEP is unreachable, nothing happens and the person fills the address by hand: the checkout is never blocked by a lookup. Stores that prefer to turn it off can return false from the ballitech_cf_buscar_cep filter. #### Included fields * Person type (individual or company), which shows either CPF or CNPJ * CPF, with check digit validation * CNPJ, numeric and alphanumeric, with validation * State registration (inscricao estadual) * Street number and district, on both billing **and** shipping, so the shipping label comes out right * Input masks for CPF, CNPJ, postal code and phone * Address lookup from the Brazilian postal code (CEP) #### Compatibility * Block checkout and classic checkout * HPOS (High-Performance Order Storage), declared and tested * WooCommerce 8.9 or newer ### Is there a paid version? Yes, and this plugin is complete without it. Everything described above is free and stays free: the fields, the validation, the alphanumeric CNPJ, the migration and the postal code lookup. **Ballitech Checkout Fields Pro** adds one thing only: it looks the CNPJ up at the federal tax authority and fills in company name, address, district and postal code by itself, warning you when the company is no longer active. It is a separate plugin, distributed outside this directory, and nothing here depends on it. ### External services This plugin uses **ViaCEP** (https://viacep.com.br) to fill in street, district and city from the postal code typed by the customer. * **What is sent:** the postal code typed by the customer, and nothing else. * **When:** at the moment the customer finishes typing the 8 digits, from their own browser. The store server does not take part in the request. * **Terms of use and privacy policy:** https://viacep.com.br To turn the lookup off, use this filter: ``` add_filter( 'ballitech_cf_buscar_cep', '__return_false' ); ``` ## Screenshots [⌊The fields in the block checkout.⌉⌊The fields in the block checkout.⌉[ The fields in the block checkout.

Install and activate the plugin. 2. That is all. There is no settings screen; the fields appear at checkout. 3. If you were using _Brazilian Market on WooCommerce_, **deactivate it**. Your data has already been imported. 4. Open **WooCommerce > Ballitech Checkout** to confirm everything is green. ## FAQ ### The fields show up twice. What happened? Either the old plugin is still active, or your WooCommerce already draws the fields on its own and compatibility mode is switched on for nothing. Open **WooCommerce > Ballitech Checkout**: the page tells you which of the two it is, in one line. ### Will my invoicing software keep working? Yes. The plugin writes to the same keys _Brazilian Market on WooCommerce_ used (` _billing_cpf`, `_billing_cnpj`, `_billing_number`, `_billing_neighborhood`), which is where invoicing tools read from. ### What is an alphanumeric CNPJ? A CNPJ with letters in the first 12 positions, issued by the Brazilian federal tax authority since 31 July 2026. Older CNPJ numbers, made of digits only, stay valid forever: there is no migration and no renumbering. ### Do I need to configure anything? No. If you need to change the behaviour, the code documents the available filters. ### Does it work with the classic (shortcode) checkout? Yes. The plugin detects which of the two the store uses and adapts. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Ballitech Checkout Fields for WooCommerce” is open source software.
