alg_wc_eu_vat_advanced_vat_shifted_text, default VAT Shifted): the reverse-charge note shown when VAT has been exempted.
Other invoice plugins #
Any invoice plugin can read the number directly from the order meta key _billing_eu_vat_number. If your invoice tool supports custom fields, point it at that key to print the VAT number.
