Czech EET System Confirms Sales with POK Code

• The Czech Ministry of Finance says the EET system confirms successful sales submissions with a POK code returned to the cash register.
• Each properly received sales record gets its own unique POK, linked to the original message by the taxpayer’s assigned number.
• If validation checks fail, the message is rejected and no POK is issued.
• The POK format includes a UUID from the receiving EET device and a two-digit hexadecimal device ID.
• The POK serves only as proof that the sale was successfully recorded by the tax authority’s system.
