About USPhoneGen
USPhoneGen is an online SMS reception service that provides temporary virtual phone numbers for receiving OTP verification codes. According to its website, its numbers are primarily US-based and come from carrier-grade infrastructure, supporting 700+ services (availability varies by region), with verification codes usually delivered within seconds and a claimed delivery rate of 90%. Each number is used for a single session only and is released after use; if no verification code is received before the number expires, credits are automatically refunded. The workflow is: create an account, top up credits, choose a service and country/region, request a temporary number, and receive SMS in the console. Credits never expire, and no subscription or monthly fee is required.
