A bank account on Pay By Group has two parts: an identity check and a payment destination.
The easier one to check is the payment destination component. The site asks for the Name On Bank Account, your Routing Number, and Account Number.
Usually the Routing Number is what trips people up. Pay By Group needs the electronic routing number for ACH payments, not the number for wire transfers. This number is typically 9 digits long. If you need help finding it, contact email@example.com
The identity check is more finicky. Pay By Group's bank is trying to make sure you're a real person before it pays this group to you. Double check all your information to make sure it is current. The most common problem with this section is the Address field, which prefers simpler answers to more complicated ones. My address might well be 5018 Blue Street Tower 2 Suite 306 Apt 404c, San Francisco, CA but for our field, I should just write "5018 Blue St."
