If the first few cards in a batch connect without issue but subsequent ones start erroring out, your bank has most likely flagged the repeated connection requests as potential fraud and begun blocking them automatically.
This is a bank-side safety measure — it is not an issue with Vergo or your cards themselves.
How to fix it
Call the number on the back of the affected card(s) and tell the representative that you are connecting your corporate cards to an expense management platform.
Let them know the connection attempts are legitimate and ask them to approve the requests and remove any fraud block on your account.
Once the bank confirms the block has been lifted, return to Vergo and retry connecting the remaining cards.
⚠️ Note: if cards continue to fail after the bank has cleared the block, contact Vergo support with the affected cardholder names and card last-four digits so we can check for any errors on our side.
