Is there a phone verification API? by Rahul Am

Answer by Rahul Am:

[Disclaimer: I am working for 2Factor [1], who builds in-house OTP solutions]

2Factor offers simple RESTful APIs for integrating phone verification into any third party application.

Why I Feel 2Factor’s Offering Is Better:

  • 2-6 SEC DELIVERY

    2Factor manages direct connectvity with Vodafone and Airtel ( Which are most preferred telcos for OTP use cases )

    Direct Connectivity with TIER-1 Telcos helps in achiving 2–6 seconds average delivery time ( Faster delivery )

  • FAIL-OVER HANDLING

    Proprietary routing algorithms Re-routes any failed messages ( in real-time ) via backup operators to ensure higher delivery rates

  • PAY PER DELIVERY ( SLA Driven )

    2Factor is the only known OTP provider, who offers SLA driven pricing.

    You are charged only if
    – OTP is delivered +
    – OTP is delivered within 15 seconds

  • DATA PRIVACY

    Several messaging vendors in India have been observed selling your customer’s phone numbers to data harvesting companies ( for helping them launch bulk messaging campaigns )

    2Factor is the only known OTP provider, who offers DATA MASKING functionality to hide instruct 2Factor not to log your customer phone numbers in sms logs.

    This ensure higher privacy of your client contact numbers

  • BUILT TO SCALE

    With several SALES focused companies, users have always seen complaining about delays in SMS delivery, Latencies in API response time.

    To address such issues, 2Factor always ensures to offer you sufficient thruput / transaction per second limits to deliver your messages promptly.

  • REAL TIME REPORTS

    2Factor also offers detailed and real-time delivery report sent to your callback URL, so your server can be notified in real-time about the actual message delivery status.
