Why Standard VoIP Numbers Fail on OpenAI / ChatGPT & Claude
OpenAI employs Twilio Lookup to check line types. If the line type is returned as "voip" or "prepaid virtual", OpenAI displays: "It looks like this is a virtual phone number (also known as VoIP). Please provide a valid mobile number." BurnOTP provides authentic mobile lines that return "mobile" or "landline-physical", ensuring 100% acceptance.
