Error code 400 and 403 are usually only around when something that isn’t allowed on the Venmo platform is attempted. It is fairly easy to avoid these error codes if you know what you’re doing.

Use A Different Phone Number

If the phone number you’re currently using is not working, it might be connected to the fact that your number is registered to another account.

If you previously created a Venmo account connected to your Facebook, this could be the answer. Venmo usually integrates the phone number from Facebook into your profile. This could have been done to you unknowingly. If you’ve got a different number, it’s best to use it.

If your DNS Cache is out of sync, this error can appear on your PC. Here’s how to flush the DNS.

  1. Go to your Windows Search bar and type in “CMD”
  2. Right-click on Command Prompt and Run as Administrator
  3. Type ipconfig /flushdns and hit Enter on your keyboard

Check for URL Syntax Error
