South Korea temporary number for OTP
OTP Bolt gives developers and privacy-minded users a temporary +82 number for South Korea verifications — pick an app, get the number, and watch the code appear in seconds.
Why use a local South Korea number?
South Korea is a East Asia market where SMS remains the default second factor for apps like KakaoTalk and Toss. Many services check that the number's country matches the account region, so a native +82 line passes where a foreign one is rejected.
Tips for South Korea verifications
- Format: +82 10 XXXX XXXX. Paste the number exactly as shown — OTP Bolt already includes the +82 prefix.
- Language: most South Korea services send codes in Korean; the inbox shows the full SMS text so you can read context, not just digits.
- When a code doesn't show within two minutes, cancel and rent another number; you're only charged when an SMS actually arrives.
- For long-running South Korea accounts that need repeat logins, a temp number is the wrong tool — use a dedicated number or your own SIM.

If the rental window closes without a message, the full price returns to your wallet automatically. You can also cancel early once the network allows it.
Can I keep a South Korea number long term?
