We want to inform you of an operations update in preparation for the holidays. WEX, our third-party virtual credit card supplier, will perform a bank identification number migration (BIN) starting on September 16, 2019. 

 For context, there will be a slight change to the initial six digits of the virtual credit cards that we provide to merchants when purchasing goods. Currently, our BINs start at USD 555237. Once updated, the numbers will be USD 555244.

No action is required unless you are hardcoding and/or whitelisting BINs. If so, we recommend that you validate the algorithm still works post-migration to ensure the WEX cards have not fallen out of range due to the minor change.  Please reach out to your dedicated Client Success Manager with any questions.
