Millions of Americans carry a reloadable prepaid Mastercard—whether it is a Netspend Prepaid Mastercard, a Brink’s Money Prepaid Mastercard, a Green Dot Everyday Prepaid Mastercard or an online-issued Walmart MoneyCard Mastercard. When you try to buy Bitcoin with a prepaid Mastercard, however, you run into a double filter: not only do major exchanges block prepaid Bank Identification Numbers (BINs), but one of the largest crypto card processors in the United States restricts American card buyers to Visa only. This guide explains why a prepaid Mastercard behaves differently from a prepaid Visa in the US, where a 3-D Secure prepaid Mastercard can still work, and how to use your card account’s built-in ACH routing numbers to buy Bitcoin without a single card decline.
The short answer on buying Bitcoin with a prepaid Mastercard
If you hold an unregistered store-bought Mastercard gift card (such as a single-load Vanilla Mastercard Gift Card), it will not work on any regulated Bitcoin exchange. If you hold a personalized, reloadable prepaid Mastercard verified in your legal name, here is what works:
- outside the US (Europe, UK, Global): Both Simplex and Paybis accept reloadable prepaid Mastercards that support Mastercard Identity Check (3-D Secure) and international online payments, provided your issuer does not block MCC 6051 quasi-cash transactions.
- Inside the United States: Simplex blocks all US Mastercards for crypto purchases (accepting US Visa only). That leaves two paths for US prepaid Mastercard holders: trying a 3-D Secure checkout like Paybis, or—much more reliably—using the ACH bank routing and account numbers inside your verified Netspend, Brink’s or Green Dot account on a licensed US exchange.
Buying Bitcoin with a prepaid Mastercard vs spending crypto on a Mastercard
Make sure you don’t mix up the two directions:
- This guide (`/buy-bitcoin-with-prepaid-mastercard`): Covers using a fiat-loaded prepaid Mastercard (from a supermarket rack, payroll program or reloadable provider) to buy Bitcoin.
- Our crypto prepaid Mastercard hub (`/crypto-prepaid-mastercard`): Reviews cards that let you spend your crypto or stablecoins at Mastercard merchants—such as the MetaMask Card, Bybit Card, Nexo Card, OKX Card, Bleap and Binance Card Brazil.
Major US prepaid Mastercard programs and how they work
One reason “buy Bitcoin with a prepaid Mastercard” is searched so heavily is that three of America’s biggest reloadable card brands issue on the Mastercard network:
| Prepaid Mastercard Brand | Program Manager & Issuing Bank | Dedicated Guide | Best way to buy Bitcoin with it |
|---|---|---|---|
| Netspend Prepaid Mastercard | Ouro Global · Pathward, N.A. or Republic Bank & Trust | Netspend guide | Use Pathward/Republic ACH routing numbers or Paybis 3DS |
| Brink’s Money Prepaid Mastercard | Netspend network · Republic Bank & Trust / Pathward | Brink’s guide | Use Online Account Center ACH routing numbers |
| Walmart MoneyCard Mastercard | Green Dot Corporation · Green Dot Bank, Member FDIC | Walmart MoneyCard guide | Use Green Dot Bank ACH routing numbers (or switch to OnePay) |
| Green Dot Everyday Mastercard | Green Dot Corporation · Green Dot Bank, Member FDIC | Green Dot guide | Use Green Dot Bank ACH routing numbers |
| Skylight ONE Debit Mastercard | Netspend Payroll · Axos / Regions / Pathward / Republic | Skylight ONE guide | Use ACH or transfer wages to a checking debit card |
What if you hold a personal bank debit Mastercard from a US neobank—such as the Albert Cash Mastercard (issued by Sutton Bank) or the OnePay CashRewards Mastercard (issued by Coastal Community Bank or Lead Bank)? Those are true bank debit cards, not prepaid cards, so exchanges like CEX.IO, Coinbase and Kraken accept their BINs directly.
Why US prepaid Mastercards hit a wall at Simplex
When you tap “Buy Bitcoin” inside many self-custody wallet apps, the app routes you to Simplex because Simplex is the one major processor whose help center explicitly says: “We also accept virtual and prepaid cards.” However, read three lines further down on Simplex’s official card rules page:
Many US cardholders assume their Brink’s or Netspend Mastercard was blocked by their bank, when in reality the wallet widget routed them to Simplex—which blocks all US Mastercards by policy.
How major crypto platforms treat prepaid Mastercards vs bank debit Mastercards
| Platform | Prepaid Mastercard (Netspend, Brink’s, Green Dot) | Personal Bank Debit Mastercard (Albert, OnePay) | ACH Bank Transfer from Account |
|---|---|---|---|
| CEX.IO | Discouraged (most prepaid swipes fail) | Supported (+ Apple/Google Pay) | Supported ($0 ACH deposit in ~39 US states) |
| Paybis | Conditional (requires 3DS + legal name) | Supported (with 3DS) | Not standard |
| Simplex | Blocked in US (accepted outside US) | Blocked in US (Visa only in US) | Not offered |
| Coinbase | Refused by prepaid policy | Supported (with 3DS) | Supported via Plaid |
| Ramp / Banxa / Mercuryo | Refused by prepaid policy | Supported | Supported in select regions |
The ACH escape hatch: turning a US prepaid Mastercard into a bank transfer
Here is the good news if your money is already sitting on a personalized Netspend, Brink’s, Green Dot or Walmart MoneyCard Mastercard: once you pass USA PATRIOT Act identity verification, every single one of those accounts gives you a 9-digit bank routing number and an account number inside its Online Account Center or mobile app.
- Prepaid MastercardBlocked by US Simplex & Coinbase
- Open Account CenterCopy routing & account numbers
- Link via US ACHMoves over bank rails, not Mastercard
- Buy Bitcoin$0 ACH deposit fee & no MCC 6051 block
When you fund a licensed US exchange via ACH using those routing and account numbers, the exchange never touches the Mastercard network, never sees a prepaid BIN, and never triggers a $1–$2 Pay-As-You-Go card swipe fee.
Step by step: buying Bitcoin when you hold a prepaid Mastercard
- 011. Activate your personalized Mastercard and verify your ID
Never attempt a crypto purchase with an unverified temporary rack card. Make sure your legal name is embossed on the card and your street address is on file.
- 022. Use your account’s ACH routing and account numbers in the US
Log in to your card’s Online Account Center (Netspend, Brink’s or Green Dot), copy your Direct Deposit routing and account numbers, and fund a regulated US exchange via ACH.
- 033. If testing a card swipe at Paybis, enable Mastercard Identity Check (3DS)
Ensure your phone number can receive SMS one-time passcodes, turn off any VPN or ad blocker, and leave $10+ extra balance for per-purchase or cross-border fees.
- 044. Or switch to a personal bank debit card (OnePay, Albert, Chime, Varo)
True bank debit BINs avoid prepaid card bans altogether and work with Apple Pay and Google Pay.
If you live in the United States and hold a prepaid Mastercard from Brink’s, Netspend or Green Dot, do not waste time typing the 16-digit card number into wallet widgets—Simplex blocks US Mastercards and Ramp/Banxa block prepaid BINs. Go straight to the Direct Deposit tab in your card’s app, grab your routing and account numbers, and use ACH—or open a free Chime, Varo or OnePay account.
For US buyers who want to pay with a personal Visa or Mastercard debit card, Apple Pay, Google Pay or an ACH bank transfer, CEX.IO has operated since 2013, is registered with FinCEN as a Money Services Business (NMLS 1804170) and holds state Money Transmitter Licenses in about 39 US jurisdictions (excluding New York and California).
