Google Ads charges your billing profile as your campaigns run, so your card details need to be set up correctly before ads go live. This guide walks through what you need, how to add a Coinepay virtual card during sign-up or in your billing settings, and how to troubleshoot the most common reasons a card is declined.
Before you start, make sure you have registered with Coinepay and completed identity verification (KYC). You can create your account and manage everything from the iOS app, the Google Play app, or the 24/7 self-service dashboard. Each Coinepay virtual card comes with its own card number, expiry date and CVV.
What you need before you pay
- A Google account and access to the Google Ads interface.
- A verified Coinepay account with an active virtual card and available balance.
- Your real business or personal billing details, including the billing address tied to your payments profile.
- Your correct billing country and currency, since these determine which payment settings and methods Google shows you.
Use your real identity and real billing information throughout. Google screens payment details, and mismatched or inaccurate data is one of the most common causes of a failed charge.
Understand Google Ads payment settings
Google Ads does not sell fixed-price subscription tiers. Instead, it offers payment settings that depend on your billing country, currency and account eligibility:
- Postpay (formerly automatic payments): Google charges you after your ads run, on the first of the month or when your account hits its payment threshold, whichever comes first.
- Prepay (formerly manual payments): you add funds before ads run, and ads stop once the funds are used up. A minimum payment transaction may apply. Note that prepay is unavailable in the US and Canada, among other listed locations.
- Monthly invoicing: an approved credit line for eligible businesses, not a card-based option. Google says it does not accept credit-card payments against these invoices.
Google states there is no minimum spending commitment. For most campaigns your monthly spending limit is about 30.4 times your average daily budget, and a single day's cost can reach twice that average. These are spending limits set by your budget, not prices.
Step-by-step: add your Coinepay card and pay
- Sign in to Google Ads and begin creating your account. You can add business information and choose campaign goals and a budget, or create an account without a campaign.
- When prompted, select or create a payments profile and enter your billing country. This choice is important and generally cannot be changed later.
- Choose your payment setting (postpay or prepay, where available) and then select the card option as your payment method.
- Enter your Coinepay virtual card number, expiry date and CVV, exactly as shown in the Coinepay app or dashboard.
- Enter the billing address that matches your payments profile, then select Submit.
- Google may place a temporary card authorization or take a small refundable verification prepayment to confirm the card works. Make sure your Coinepay balance covers this.
To review or change your card later, go to Billing → Settings for payer details, payment settings and payment methods. Use Billing → Summary to see balances, charges and payment status.
Important card-type restriction to check first
Google's supported card networks vary by country, and Google's UK guidance lists Visa and Mastercard credit and debit cards. A single worldwide list of accepted cards is not published, so the options shown in your own account are authoritative.
Crucially, Google says prepaid cards are not accepted for postpay. In India, Google allows Visa and Mastercard to be saved, lets RuPay be used for individual payments but not saved, and does not support American Express, Diners or Discover for Google Ads.
Because acceptance depends on your card's type and network, contact Coinepay support to confirm your card meets Google's requirement before you rely on it for billing. You can reach the team through Coinepay support or on Telegram.
Managing spend with a dedicated card per account
If you run several ad accounts, Coinepay lets businesses issue a dedicated virtual card for each one and set a custom spending limit per card. Keeping one card per Google Ads account makes it easier to reconcile charges, control exposure on each account, and spot an unexpected decline quickly.
Troubleshooting: why a Google Ads card payment is declined
When a newly added card cannot be charged, Google may show an error asking you to correct the card details or select another payment method. Google lists these as common decline reasons, and Billing → Summary shows the decline reason if it is available; otherwise you need to ask your card issuer.
| Cause | What to do |
|---|---|
| Insufficient funds | Check your Coinepay balance in the app and top up so it covers the charge plus any verification authorization. |
| Exceeded credit or transaction limits | If you set a per-card spending limit in Coinepay, raise it or spread spend across your dedicated cards. |
| Incorrect card number or CVV | Re-enter the number, expiry and CVV exactly as displayed in your Coinepay card details. |
| Expiration | Confirm the card is still valid; replace it in Billing → Settings if it has expired. |
| Billing address mismatch | Make sure the address on your Google payments profile matches your real billing details. |
| Online/international transaction restrictions | Verify the card is enabled for online and international purchases; check your Coinepay settings or ask support. |
| Failed required authentication (3-D Secure) | Complete any verification prompt Google or the issuer sends, and make sure you can receive it on your registered device. |
If the decline persists after these checks, confirm with Coinepay support that your card is suitable for Google Ads billing, and confirm in Google that your billing country and currency are correct.
Regional and eligibility notes
Google Ads is unavailable to advertisers in Crimea, Cuba, Iran, North Korea, and the so-called Donetsk and Luhansk People's Republics due to sanctions restrictions. Updated Google Ads Terms of Service took effect on 1 July 2026, with payment-language references to regulatory or jurisdiction-specific fees in some regions. Google has also noted that PayPal is temporarily unavailable for new postpay accounts, and that Boleto is temporarily unavailable for new Brazil accounts except monthly-invoicing ones. Always rely on the options your own account displays.
Cancellation and refunds
An administrator can cancel at any time via Admin → Preferences → Account Status → Cancel my account. Ads may take up to 24 hours to stop, and charges you already incurred remain payable. Eligible unused funds are generally refunded to the original payment method after cancellation; Google estimates 4–12 weeks for a cancellation refund, while its separate guidance says card refunds are typically processed within two weeks before bank time. Eligible active accounts can request a refund of positive credit at Billing → Summary, though Google excludes active-account refunds in Argentina, Brazil, China, India, Mexico, Russia, South Korea, Taiwan and Ukraine. Keep your Coinepay card active until any refund clears.
Check prices on Google's official pages
Google Ads costs depend on your bidding, budget and the auction, so there is no standard price to quote here. Confirm current pricing, fees and availability on Google's official Google Ads and support pages for your country, and manage your card and balance in the Coinepay app. Some services are not available in every jurisdiction, and services related to virtual assets are not available to residents of mainland China.
