Google is a service that provides its users a number of amazing facilities which they can enjoy anytime and with any application of Google, be it Google Drive, Google Photos, Google sheets, Google mails, etc. There is no doubt in the fact that Gmail is one of the best services of Google. But there are times when this service also faces glitches like Google verification code not coming. If you are not getting a verification code even after the two-step verification or authentication method, then there might be plenty of reasons for the same. But do not worry this problem can be resolved in simple ways; you are just needed to follow them carefully.
The first thing you should focus on is the device on which you are requesting the code. You have to request for the code on the device which is linked to your Gmail, you will not get the code if you will request it on any other device.
The second thing you should check is the signal or the network connection of the device on which the code is being requested. If the device does not have good signals, this can be the reason for the Gmail verification code not being received.
If there are no such problems that are listed above, then the users should wait for a few minutes to get the code. Sometimes, because of the technical glitches, the users might not receive the code immediately but after some time it is sent from the Gmail services.
