<\/span><\/h2>\nRequesting a second code is an instinct when the first one seems slow to arrive. But here’s what happens behind the scenes: each new request invalidates the previous code. When you tap resend, Koho generates a new code and invalidates the old one.<\/span><\/p>\nThe most common mistake:<\/span><\/strong> entering the first code you received after requesting a second one. Even if the first code was perfectly valid when it arrived, it’s now useless. Koho only accepts the most recent code generated for your session.<\/span><\/p>\nCheck the timestamps on your SMS messages.<\/span><\/strong> The code in the message with the latest timestamp is the only valid one. Delete old verification threads before requesting a new one to avoid confusion.<\/span><\/p>\nIf you tapped resend multiple times,<\/span><\/strong> only the last code is valid. All previous codes are invalid, whether you used them or not.<\/span><\/p>\nAnother scenario:<\/span><\/strong> you requested a new code, but your phone never received it. In this case, the old code is still invalid because the new request superseded it. Wait a few minutes and request it again, but this time, request it only once.<\/span><\/p>\nA practical tip:<\/span><\/strong> after requesting a new code, wait at least 60 seconds before entering it. This gives the SMS time to arrive and ensures you use the most recent message, not one still in transit.<\/span><\/p>\nThe resend trap is one of the most common causes of persistent OTP errors. Once you understand that only the latest code works, you’ll avoid this issue entirely.<\/span><\/p>\n<\/span>Koho Says Wrong OTP But the Code Is Right? Check Your Number Format<\/span><\/strong><\/span><\/h2>\nSometimes the code you enter is valid, but Koho still rejects it. When this happens, the problem is usually the phone number format stored in your account.<\/span><\/p>\nKoho requires a full international format.<\/span><\/strong> Save your number as +1XXXXXXXXXX for US\/Canada numbers, or +[country code][number] for other regions. If your profile uses a local format without the country code, SMS may route incorrectly, or the code may be generated for a different number than the one you’re using.<\/span><\/p>\nCheck your Koho profile:<\/span><\/strong> Go to Settings > Personal Info > Phone Number and verify the format. Make sure there are no leading zeros (e.g., +1 0XXXXXXXXX is wrong) and no spaces or dashes.<\/span><\/p>\nIf you recently ported your number or changed carriers,<\/span><\/strong> update it in the app. Even if your number is technically the same, the carrier routing may have changed, and Koho needs the current information.<\/span><\/p>\nTry toggling airplane mode on and off.<\/span><\/strong> This refreshes your phone’s network connection and can trigger the delivery of pending SMS messages.<\/span><\/p>\nIf your number format is correct but codes still fail,<\/span><\/strong> the issue may be on Koho’s end, specifically, their SMS gateway. In that case, no amount of troubleshooting on your part will fix it. Your options are to wait and try again later, or use a different number for verification (covered below).<\/span><\/p>\nApple’s support documentation offers general guidance on how phone numbers are used for SMS-based features, which can help clarify format requirements.<\/span><\/p>\n<\/span>How to Fix Koho Wrong OTP by Using a Different Number<\/span><\/strong><\/span><\/h2>\nIf your carrier consistently delays or drops verification SMS, the fastest permanent fix is to switch to a different number. You have two options: update your Koho profile with a new personal number or use a paid virtual number to receive verification codes.<\/span><\/p>\nOption 1: Change to a different personal number<\/span><\/strong><\/p>\n\n- In Koho, go to Settings > Phone Number > Change Number.<\/span><\/li>\n
- Enter the new number in full international format (e.g., +1XXXXXXXXXX).<\/span><\/li>\n
