What changed: According to the source, WooCommerce 11.2.1 fixes two issues from 11.2.0: stores removing address fields via the woocommerce_billing_fields or woocommerce_default_address_fields filters could see checkout blocked, tax not charged, or shipping options disappear; and the checkout block rejected valid postcode formats for Argentina, El Salvador, Saint Vincent and the Grenadines, and the British Virgin Islands.
Who is affected
WooCommerce stores that remove address fields via the woocommerce_billing_fields or woocommerce_default_address_fields filters, and stores receiving orders from Argentina, El Salvador, Saint Vincent and the Grenadines, or the British Virgin Islands.
What it means for your business
For businesses using WooCommerce, this means the checkout-blocking bug from 11.2.0 affecting customized address fields and certain country postcodes is resolved in 11.2.1.
What to do
If your store uses the woocommerce_billing_fields or woocommerce_default_address_fields filters, or receives orders from the listed countries, update to WooCommerce 11.2.1 and test both classic and block checkout.
When it takes effect
Version 11.2.1 has been available for download since October 9, 2026; the source gives no other effective date.
