I am Samuel and I will help you. So you're trying to register for Uber and they're sending you a validation code via text that you are not receiving?
Who is the mobile carrier for your phone?
When signing up to ride with Uber you must provide and verify your mobile number.
After you provide your number, we send you a verification message. If you confirm that you entered your correct phone number but did not receive this message immediately, it is likely your mobile carrier may be blocking the short code SMS that Uber uses to contact you.
Please contact your mobile provider to confirm that short code SMS is enabled for your mobile account.
After confirming, if your phone still hasn’t received a verification SMS, please share your mobile number at the link below. We’ll make sure your account is set up correctly.
