The selected project and billing account cannot pay for Maps in your region. Select an existing project that is paid for by a Maps billing account

This problem happens after enabling the billing method using a Pakistani Credit Card, and Billing details also fill up as Pakistani Addresses.

The selected project and billing account cannot pay for Maps in your region. Select an existing project that is paid for by a Maps billing account.

I have this problem while creating a Flutter Application using Google Map SDK.

Solution:

I have searched several sites and discovered that the problem is due to creating Pakistani Billing Addresses.

Why does this problem happen?

Google Cloud Console supports INR, USD and Rupee, but for using Google Map SDK / Enabling Map Billing, the account has to be USD Support.

How to solve this ?

First of all, check if you've enabled the API you're trying to use, or second, you must check the billing account type, go to an overview of your billing account, and there you'll find it. If it is a cloud console type, then you've to create another project and link it with another billing account with maps (that's what I've done, and still trying to find a way to merge both of them) and, most importantly, maps billing account won't in INR it'll be USD, The INR is allowed only of cloud console billing account not on Maps Platform.
