Yahoo offers many excellent features and is easy to use, but some users have problems. Some common problems are related to the Yahoo verification code email. One reason for the Yahoo verification code not being received is that you have entered incorrect recovery information or no longer access your recovery phone number or email address. Moreover, you need to enter a mobile number to receive verification codes; entering a landline number will not do the job. Further, check the device you are using to receive the verification code that it should not have hardware issues and have sufficient memory to receive the code. In some cases, Yahoo verification codes end up in the spam folder of your account, which makes them inaccessible.
