Unlock phone request - says information is invalid

@random_user1, we want to help get your device unlocked. 

Let’s meet in a Direct Message to work on getting your device unlocked together.  Please check your Direct Message Inbox (it’s the chat icon next to the bell icon in the upper right corner of the Forums).

In the meantime, here is more information on our eligibility requirements. Prepaid devices must be active for at least six months of paid service. You did mention that you've had service for more than a year. Your phone should eligible to be unlocked.

Here's the list of general requirements for all unlock requests: 

• The device must be designed for use on, and locked to, the AT&T wireless network. 
• It must not be reported lost or stolen.
• It’s not associated with fraudulent activity.
• All the device’s service commitments and installment plans are completed, and all early termination fees are paid in full.
• The device is not currently active on a different AT&T customer’s account.
• If you performed an early upgrade, you must wait the 14-day buyer’s remorse period before you can request to unlock your previous device.
• Visit our Unlock Support page for the full requirement list. 

How to request a device unlock:

1. Go to our Device Unlock portal.
2. Select Yes if you are an AT&T Customer, No if you are not an AT&T customer. 
3. Enter your telephone # if you are an AT&T Customer. Enter your IMEI if you are a non-AT&T Customer.
4. Follow the prompts. 

We look forward meeting you in a Direct message to help get your device unlocked. 

Thank you for contacting AT&T Community Forums.
