I haven't received the SMS code

We send SMS codes to the mobile phone linked to your OKX account. Codes may take some time to arrive, and each is valid for 10 minutes. Your account will be locked if you enter incorrect codes 6 times within a period of time. If you're not receiving codes, try these solutions:

  • Clear your browser or mobile app cache, then request a new code.

  • Request a code on different OKX platforms: desktop browser, desktop app, mobile browser, or mobile app.

  • If you can't log in, switch to other alternatives, see the steps below to know how it's done.

Note: SMS security codes are only sent through standard mobile carriers. Other messaging services (such as WhatsApp, Telegram, or third-party apps) are not supported for receiving SMS verification codes.

How can I troubleshoot when I don't receive the SMS code?

If you’re having trouble receiving verification messages, try the following:

  • Restart your phone: Long device uptime may affect signal reception. Restart your phone and try again.

  • Check dual SIM settings: If you’re using dual SIM, try swapping the SIM card slots and resend the verification message.

  • Check storage space: Make sure your SMS inbox isn’t full. Delete old messages if necessary.

  • Review blocked messages: Check whether security apps or system settings are filtering or blocking SMS messages.

  • Disable SMS-blocking apps: Temporarily turn off any SMS-blocking or filtering apps on your device.

  • Check carrier status: Visit your mobile carrier’s official website or app to confirm whether the message was successfully delivered.

  • Use voice verification: Wait 60 seconds, then select Voice Verification to receive a call instead of an SMS.

  • Cooling period after failure: If you see “SMS sending failed,” wait about 2 hours before trying again.

  • Number portability issues: If you recently switched carriers while keeping the same phone number, delivery issues may occur. Please inform customer support for further assistance.
