There are two ways to check your Wells Fargo account number. The first way is to log in to your Wells Fargo online account, click on the type of account you have, and then click on the four last digits under the name of the bank account. The second way is to open the Wells Fargo app, log in, tap "Accounts," select your account, tap "Details," and verify your identity. Routing numbers and account numbers are also available in Wells Fargo Online.

I hope that helps! Let me know if you have any other questions.
