The 1win sign up form is short, but two of its fields deserve a pause: the currency and the login method. Below are the five steps in order, then what to prepare for the identity check that comes later. You must be 18 or older. Most people finish in a few minutes; the extra care is in the choices, not the typing.
Open the official 1win site, the Android app, the iPhone web app or the Windows client and tap the registration button.
Enter a phone number or email address and a strong password, or use Google or Telegram where offered.
Set baht as the account currency. It is fixed once the account is created.
Add a promo code if you have one. The field can be left empty.
Add about ฿200 to ฿350 or more and keep or untick the welcome offer in the cashier.
Use a phone number or email you will still have in a year. If you lose access to it, recovering the account becomes harder.
Choose a password you use nowhere else. A password manager on your phone is safer than a note in your gallery.
On currency, THB makes sense for most players in Thailand. Even if you plan to deposit with crypto, the cashier converts the amount, and every bonus and payout figure stays easy to read in baht.
Take a moment with 1win's terms before you confirm. They set out the one-account rule, the bonus conditions and the verification policy.
Leave the promo code field empty if you do not have a code from a source you trust. It is optional, and an empty field does not block registration.
Finally, think about the bonus before the first deposit. The welcome offer is ticked in the cashier by default where it applies, and it carries 40x wagering. If you only want to try the lobby with a small amount, unticking it keeps things simple.
The 1win sign up itself needs no documents. ID is requested once withdrawals pass about $500 in equivalent, or whenever 1win asks.
A passport or a Thai ID card is fine. Make sure the name matches the one on your account and payment method, and send a clear, uncropped image.
Expect the review to take a day or two in most cases. Sending documents early in the life of the account means a larger withdrawal later does not wait on paperwork.
Keep only one account. Duplicates are closed, so registering again with different details only creates problems.
Payment methods should be in your own name too. A card or bank account belonging to someone else is a common reason for extra questions during the check.
If something goes wrong during the check, for example a photo is rejected as unclear, live chat is open 24/7 and can tell you what to resend. Email is there for anything that needs a longer reply.
Once verified, the account is fully set up. From then on, withdrawals depend mainly on the method: crypto usually within hours, bank transfer and e-wallets within 24 hours, cards in 3 to 5 working days.
A few minutes. Verification, if requested later, usually takes a day or two. There is no waiting time before your first deposit.
Where offered, yes. Google sign-up is also available in some cases. Either way, the account works the same once it is open.
It cannot be changed. Contact live chat for help, but plan to choose carefully from the start. Choosing THB from the start avoids the problem for most players in Thailand.
A Thai ID card or passport, usually requested once withdrawals pass about $500 in equivalent. Send a clear, uncropped image so the review is not delayed.
