The invalid error after a resend usually means the previous code was voided, not that your new code is broken.<\/span><\/li>\n<\/ul>\nThe takeaway: each resend makes things worse. The system is rate-limiting you, and the only fix is to stop.<\/span><\/p>\n<\/span>How to Use Another Number for OfferUp Verification\u00a0<\/b><\/span><\/h2>\nIf your current number keeps failing, OfferUp lets you switch to a different number during verification. In the app, go to Settings \u2192 Account \u2192 Phone Number \u2192 Change, and enter the new number. The system will send a fresh code to the new number, wait for it before closing the screen, and don’t request a resend unless the first code fails.<\/span><\/p>\nFollow these steps:<\/span><\/p>\n\n- Open OfferUp and go to <\/span>Settings<\/b> \u2192 <\/span>Account<\/b> \u2192 <\/span>Phone Number<\/b> \u2192 <\/span>Change<\/b>.<\/span><\/li>\n
- Enter the new number and confirm it’s correct before submitting.<\/span><\/li>\n
- Wait for the SMS to arrive, don’t close the screen or navigate away.<\/span><\/li>\n
- Enter the code within two minutes of receiving it.<\/span><\/li>\n
- If it fails, wait 30 minutes before trying again; don’t switch numbers during the wait.<\/span><\/li>\n<\/ul>\n
Important notes:<\/span><\/p>\n\n- You can switch numbers mid-verification; you don’t need to wait for the old code to expire.<\/span><\/li>\n
- Use a number that can receive SMS reliably; avoid numbers with a history of failed OTPs.<\/span><\/li>\n
- After switching, the old number is no longer valid for verification, so don’t go back to it.<\/span><\/li>\n
- If the new number also fails, the issue is likely on OfferUp’s side or your device will return to the time settings fix before trying a third number.<\/span><\/li>\n<\/ul>\n
Switching to a fresh number is the fastest fix, but not all numbers accept OfferUp codes. Use a paid verification service with higher acceptance delivery varies by app and country, and you’re refunded automatically if no code arrives.<\/span><\/p>\n<\/span>OTP Error Alternative Phone: What Kind of Number Actually Works?<\/b><\/span><\/h2>\nOfferUp’s OTP system accepts most numbers, but its anti-fraud filters are stricter for certain categories. A fresh number that has never been used on OfferUp and belongs to a standard mobile line has the highest chance of receiving a code. Numbers from temporary or disposable services are often blocked outright, returning the wrong OTP error even if the code is correct.<\/span><\/p>\nWhat to look for in an alternative number:<\/span><\/p>\n\n- Numbers previously used on OfferUp (even for other accounts) may be flagged and blocked.<\/span><\/li>\n
- A number with a different country code than your account region may trigger extra verification steps.<\/span><\/li>\n
