⚡ 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 / Flash / Boundless).
📖 Overview
Many bind/subscribe failures come down to billing address. This guide explains when a generic address is OK and when it must match exactly.
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: lenient merchants — any valid US-format address
Most payment platforms check addresses loosely — a correctly formatted US address is usually enough.
Case 2: strict merchants — fill a real address matching your exit IP
On strict platforms, enter a real billing address (street, city, state, ZIP) whose country matches your current exit-IP region. The MPChat App does not provide a billing address; MPChat cards are Singapore-issued and USD-settled — not US-issued. A US-format address with a US exit IP is for AVS matching; it does not mean the card is US-issued.
⚠️ If ZIP validation fails, use a ZIP that truly matches the city/state and retry.
Case 3: address rejected — try another real address matching your exit IP
If the merchant rejects the address, try a different real address in the same exit-IP region. The App does not provide a billing address; do not invent incomplete or fake addresses.

❓ 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.

💬 Still having trouble?
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.
