Ask HN: What's the best service for phone number verification?
Considering writing an app with phone number login using a verification system - I was considering rolling my own using Twilio (asking the user to call a number and add a code or get an SMS and enter a code), but I was wondering if there are any better solutions that work OOTB.
- rcdexta 11y agoFor a mobile app, I developed recently, I tried the following services: https://www.nexmo.com/product/verify/ https://www.nexmo.com/product/verify/ https://getprove.com/ https://getprove.com/ In terms of ease of use and reliability, I preferred Nexmo. But however, I faced issues sending sms to VOIP numbers with Nexmo. I ended up using Twilio and Parse (it was the backend anyway) to get a verification service running. You can use this http://shamadeh.com/blog/web/mobile/twilio/parse/2014/07/31/VerifyPhoneNumbersTwilioAndParse.html http://shamadeh.com/blog/web/mobile/twilio/parse/2014/07/31/... as a starting point!

- rcdexta 11y agoTwilio lookup gets you details about the carrier and whether it is voice/sms enabled. Basically used to validate if you have number that enables communication. This service is not the same as the verification API the OP is talking about!
- alex_sf 11y agoTwilio has a product specifically for the 'get a code via SMS and verify it' use case: https://www.twilio.com/authy https://www.twilio.com/authy
