⚡ Quick summary (TL;DR)
Fill subscription billing addresses that match IP/account region and ZIP/state for fewer AVS failures and declines.
Keep egress region, billing address, and card details aligned; leave a balance buffer; do not rapid-retry payments.
This guide is for MPChat Pay & MPCard (Cloud / Boundless).
📖 Overview
Billing address mismatches can cause binding or payment failures. View the card address recorded in MPChat, then enter it accurately at the merchant.
What is a billing address?
Most overseas platforms ask for a billing address (card statement mailing address) for AVS (Address Verification System). If it does not match card records, binding or payment may fail.
Three scenarios — how to fill it in
Case 1: view the card billing address
Assets tab → Pay → swipe left in Total Assets to find the card → Settings → Change Billing Address. Use the recorded address rather than an arbitrary address.
Case 2: merchants with strict address checks
Enter street, city, state, postal code and country exactly as recorded for the card. View or change it at: Assets tab → Pay → swipe left in Total Assets to find the card → Settings → Change Billing Address. Cards are Singapore-issued and USD-settled; a US-format address does not make the card US-issued.
⚠️ If ZIP validation fails, use a ZIP that truly matches the city/state and retry.
Case 3: verify fields if an address is rejected
Check merchant fields against the card address. To change the recorded address, use Assets tab → Pay → swipe left in Total Assets to find the card → Settings → Change Billing Address. Avoid fabricated addresses and rapid retries; contact in-app support if it still fails.

❓ FAQ
Does billing address affect shipping?
No. Virtual-card billing addresses are for payment verification only — not physical shipping.
What if I enter the wrong address?
AVS may fail and binding/payment may be declined. Follow Case 2/3 above.
What ZIP should I use?
A real ZIP matching city/state; on strict merchants, use the ZIP for the card’s designated address.

Do not retry payments rapidly (risk systems may cool you down). Screenshot the error (mask card number & CVV), then tap the message icon in MPChat for 1:1 support.
