Do couples need separate All Indonesia arrival declaration QR codes when arriving in Bali, and is there a fee?

Do not pay for the arrival declaration itself: travelers say the All Indonesia form is free. If a website asks for payment specifically for the form or QR code, verify that you are using an official service, as it may be an unofficial site.

The visa on arrival can be arranged separately at Bali airport. According to this traveler report, it can be paid for in US dollar cash, with change given in Indonesian rupiah.

If a spouse is added as an additional traveler in the application, one All Indonesia QR code may be enough for the couple: in the reported case, scanning it registered both travelers. At the checkpoint, clarify that two people are traveling together.
