To reactivate a deactivated Mapbox account, follow these steps:
Log in to the account at account.mapbox.com.
Enter valid payment information into the persistent modal to be used for upcoming invoices.
Navigate to the account's invoices page, and click the Pay button to pay any Past Due invoices.
Please note that reactivating your account will not automatically pay Past Due invoices. You need to manually navigate to your invoices page and click the Pay button to clear any outstanding invoices. All past due invoices will need to be paid in order to keep using the account in accordance with our Terms of Service. You can find more information in our Account Deactivation guide.
