I’ve completed identity verification…

I’ve completed identity verification with Sumsub several times while registering for different online services. Each time the process has been quick and straightforward. Uploading my ID and finishing the selfie step only takes a few minutes and everything usually gets approved without delays. Overall it’s a very convenient system. The only thing I sometimes think would be useful is some kind of universal login, similar to how Gmail works, so you wouldn’t need to repeat the process on every new platform.

I was a little nervous about the KYC…

I was a little nervous about the KYC process when signing up for a new crypto exchange, since I had heard it could take hours or even days. However, the verification through Sumsub turned out to be much easier than expected. I uploaded my passport, completed the quick selfie check, and the process went smoothly. Within a few minutes I received confirmation that my identity was verified, which made the whole onboarding experience far more pleasant than I had anticipated.

Our company has been with SumSub…

Our company has been with SumSub several years now, and the service has gone drastically downhill. They recently doubled our fees without notice and you even have to pay for an account manager now. I hear others have been having same issues.

1 Star is too much

The verification is useless. I have tried uploading everything and every single one of them has failed. Whatever verification method they use for verifying document is horrible and a complete waste of time. i wish I could give 0 stars

Make sure you have a passport

Jokes can't buy crypto cause Sumsub will only except passport as I'd . Meaning mire 50% of a country are unable to buy crypto

Unfortunately a very bad and inadequate…

Unfortunately a very bad, inadequate and incompetent support Quality.Sumsub does not have any support, the way they reply is phlegmatic and indifferen and not acceptable.They simply do not care about customers concerns and forward you by saying "we can not assist you with this matter, please consult the company that asked you to verify.The funny part is....the company that asked me to verify is also unable to help me.0 of 5 Stars from me for nothing.

Nexo uses Sumsub for KYC

Hi,I was a verified customer with Nexo many years ago, but after re-login to Nexo it asked me to re-verify my identity. I questioned why but they insisted without giving me a reason. After I completed the Nexo's 3rd party provider Sumsub's verification, the screen shows "We couldn't verify your identity." I was pis*** off. Because the root cause is from Sumsub, therefore I wrote an email to Nexo saying I'm going to make a 3rd complaint to the Information Commissioner's Office UK for Sumsub and you need to manually verify me. Just before I finished writing the email, I received another email from Nexo saying I was fully verified. And also the Sumsub screen refreshed with "You've been verified." I don't know if Nexo manually verified me or I've been whitelisted by Sumsub. Because I'm verified, I changed my mind to complain to ICO UK about this time, and leave a 3 star rating for Sumsub. I used to leave 1 star rating, but I'm a fair person despite the trouble caused though I ended up with a satisfactory result. However I will leave a 1 star to Nexo for asking a fully verified customer to do kyc again.
