Depends on what you did leading up to that
I used Dolphin{anty} for this. Before registration, I checked the proxy quality and selected several different high-quality proxies.
It sounds like Tinder is flagging your account due to automated behavior. To avoid forced verification, try reducing the number of proxies you use and avoid rotating them too frequently. Stop farming cookies and let the account age naturally with minimal interaction. Using a real phone number or a more trusted verification method may also help, as SMS services can trigger flags. Slow down your activity. Don’t swipe or like too fast, as rapid actions are often seen as suspicious. Lastly, make sure each account uses unique device fingerprints, and avoid creating too many accounts in one go to prevent Tinder from detecting patterns.
It sounds like Tinder’s system is automatically flagging new accounts for verification, which usually happens when it detects unusual activity or repeated sign-ups from the same device or network, so the best approach is to use genuine information, a stable connection, and wait a bit before creating another account instead of registering multiple times quickly.
The issue is with the number, try using non-voip number. Also check your IP, it's might be blacklisted
