If your number is not at first accepted, please try dropping the initial zero, or adding it if it didn't work without one. Also make sure to enter it without any spaces or special characters in between.
When you enter your number, a four-digit code is sent to your mobile, which you are then prompted to enter into your profile. If you didn't receive the code, check whether your phone has a spam filter for sms. If it doesn't, please contact us and we will help you out!
Please note that only one account on Pawshake per user is allowed, so if your number is verified in one account, you can't verify it in another.
