How do you enable trade and the market in Knight Online?

There are two ways: do SMS approval on your account or use premium. SMS approval is done on the NTTGame account portal under Game Services > SMS Approval and costs 5 NPoint. On a premium account the market and trade work without SMS approval; NTTGame staff said the new phone rule didn't change anything on the premium side.

Since October 2026 the order has changed: you have to add a mobile number to your account before SMS approval. According to NTTGame's announcement, accounts without a number can't do SMS approval directly.

How do you do SMS approval? (after October 2026)

  1. Add a mobile number to your account: Overview > Cell Phone on the portal. The first number is free; steps in How to do phone verification.
  2. Go to Game Services > SMS Approval. The page no longer asks for a number; it shows the one you added under Overview.
  3. Send the verification code. It's texted to that number and 5 NPoint is taken from your account.
  4. Enter the code before it expires and confirm. Market and trade are now open.

Don't mix up phone verification and SMS approval: in phone verification you text 5564 yourself, while in SMS approval the code comes to you.

I already did SMS approval. Do I have to do it again?

No. SMS approval you did earlier stays valid on the current servers, and according to NTTGame players on the old servers who already did it have no obligation right now. If you like, you can sync your SMS approval number to your new account number for 5 NPoint under Game Services > SMS Approval. If you'll play on the new servers opening November 12, you still need account phone verification.

How many accounts can one number enable trade on?

In SMS approval one number can be used on at most 3 accounts. The account phone number and the SMS approval number are treated separately: you can add a number to your account as its phone, but if the same number was used for SMS approval on 3 other accounts, you'll get an error saying it's already used on 3 accounts when you try SMS approval. Then you either use another number or open the market and trade with premium.

Ways to enable trade
RouteWhat you needCost
SMS approval A mobile number on the account, and a number that hasn't filled 3 accounts in SMS approval 5 NPoint
Premium Active premium; no SMS approval needed Premium price
Existing SMS approval An approval done earlier; nothing else needed Free, stays valid

How will trade work on the new servers?

To register for the new servers you'll already have added a phone number to your account. If you move to the new servers with an account that has no SMS approval, you do SMS approval with that number for market and trade. If the number hits the 3-account limit in SMS approval, the route NTTGame points to is premium. Registration and dates are in How to pre-register for the new servers.
