PromptPay with Krungthai Bank
Krungthai Bank, ธนาคารกรุงไทย, is the state-owned one, light blue, with Krungthai NEXT as its banking app and Paotang as the government wallet alongside it. Many state payments and subsidy schemes are paid through it, which is why a lot of people hold a KTB account whether or not it is their main bank.
Registering the identifier
A mobile number or a Thai national ID number is bound to one KTB account, in Krungthai NEXT, at an ATM or in a branch. Registering the ID number here is common precisely because state payments are matched to it.
As everywhere, the menu wording shifts with app updates, so look for the PromptPay entry under the app's services or settings. The confirmation goes to the number being registered, so it must be yours.
NEXT and Paotang are not the same thing
Krungthai NEXT is the bank's app: accounts, transfers, your PromptPay code. Paotang is the state wallet used for government schemes, and it has its own balance and its own rules.
Confusing the two is the usual source of "the money is not there": it may have arrived in the wallet rather than in the bank account, or the other way round. Checking both is faster than wondering.
Reading a KTB slip
Light blue branding, then the four lines that matter: amount, receiver with part of the name hidden, date and time, reference number.
Since KTB is where many people receive state money, its slips also show up in rent and utility payments to landlords. The check is unchanged: an instant transfer means an unexplained delay is an answer, not a wait.
If KTB is your second account
Plenty of people use KTB only for state payments and another bank for daily life. That is a good reason to think about which identifier sits where: your ID number at KTB for official payments, your phone number at your main bank for friends and bills.
That split also makes your own records easier to read, because the two kinds of money never mix in one statement.
Using it with SlipDee
SlipDee builds the code from whichever identifier you registered, with your photo or logo in the middle so it can be told apart from the others in the gallery.
The slips Krungthai NEXT produces are read where they already are, in the phone's gallery, and filed against the bill they settle, so a shared rent or a split dinner closes itself.

Open SlipDeeFrequently asked questions
Is Paotang the same as Krungthai NEXT?
- No. NEXT is the bank app with your accounts and your PromptPay code; Paotang is the state wallet used for government schemes, with its own balance.
Why do state payments go to KTB?
- It is the state-owned bank, and schemes are commonly administered through it. That is also why many people hold a KTB account alongside their main one.
Can I register my ID number at KTB and my phone number elsewhere?
- Yes, and many people do exactly that. Each identifier points at one account, so two identifiers can point at two banks.
Can other banks pay a KTB code?
- Yes. PromptPay is national and bank-agnostic.
A KTB slip arrived but no money. What now?
- Transfers are instant, so after a few minutes treat it as unpaid, ask for the reference number, and check with the bank before delivering anything.
