On your Forma Card settings page, there are two addresses: Billing address and Mailing address
Billing address is usually your primary residential address you use to fulfill online orders. The billing address must match what the card issuer has on file. Please make sure to update your billing address when your residential address changes.
Mailing address is where Forma sends the Forma Card when requested from your Forma account or through the Forma app. Please make sure to update your mailing address when it changes.
