HUB3: the Croatian payment barcode

HUB3 is the 2D barcode on Croatian payment slips (uplatnica). It holds the recipient, IBAN, amount, reference model and number, and the description, and banking apps read it so the payer does not type. The Croatian Banking Association (HUB) defines it, and it is a PDF417 barcode, not a QR code.

What is inside a HUB3 barcode

The barcode holds 14 lines of text. The first line is the header HRVHUB30, the second is the currency, and the rest follow in a fixed order.

Amount
Fifteen digits with no decimal point, so 42.90 is 000000000004290.
Payer
Name, street and town of the payer. Leave them empty: the banking app fills in the payer, and this barcode is often public.
Recipient
Name (25 characters), street (25) and town (27).
IBAN
The recipient's account, which starts with HR.
Reference
A model such as HR00 and a reference number of up to 22 characters (the Croatian poziv na broj).
Purpose
A four-letter code such as COST and a description of up to 35 characters.

Details that often go wrong

  • The standard barcode is PDF417, a wide rectangle. Do not assume a banking app will read a QR code that holds the same text.
  • Mark the text as UTF-8 so č, ć, š, ž and đ survive. Scanay does it for you.
  • The amount has no decimal separator, so a missing leading zero shifts the amount by a factor of ten.

Using it in your Shopify store

Scanay makes the code for every order automatically and puts it into your Shopify order e-mails, so you never type these details yourself. It picks the right standard from the country of the order.

Questions

Is HUB3 a QR code?

No. It is a PDF417 barcode, a stacked linear barcode. Croatian banking apps read both the printed barcode and the image on screen.

Has HUB3 changed with the euro?

Croatia has paid in euro since 2023, and the barcode now carries EUR as its currency. The structure of the fields is the same.
