We can definitely assist you with signing in to your AT&T PREPAID account online. To get started, you'll need your 10-digit wireless phone number. If this is the number that you've lost in the email, we recommend that you check the settings of your cell phone, as it is usually listed there depending on the kind of device that you're using. If it isn't, you can also try calling/texting one of your contacts and asking them for your phone number. After entering your phone number at the AT&T PREPAID login page, you can follow these steps to Reset your online password or 4-Digit PIN. Let us know if this helps.
