Methodology
How DollarFerry sources and stays honest
A payment guide is only worth reading if you can trust the data. Here’s exactly how we compile the payment rules page, when we update it, what we won’t do, and how to correct us.
Who we are
DollarFerry is a small, independent editorial project run by people who have spent years doing one annoying thing repeatedly: getting overseas payments to go through from countries where local cards are declined. We’re not a bank, a card issuer, or a financial adviser. We don’t issue cards and we don’t hold your money. We publish what we learn so you don’t have to rediscover it the hard way at a checkout at 1 a.m.
How we compile the payment rules page
The payment rules page is our core resource, and this is how we put it together:
- We restate only what the official pages say. Every cell comes from the platform’s own help page, with a link to it; where the official pages are silent, we write “We didn't find this in the official pages” rather than answer for them, and we make no promises about any single product.
- We date everything. Each entry carries a “last checked” date. If you’re reading a stale date, treat it with caution.
- Each row carries its check date, and we re-check when rules change or readers report a problem.
- No numbers, just where to look. Fees, limits and day counts vary by country and issuer and they change, so we tell you which page to check instead.
Where our data comes from
Two places, in order of weight: primary sources (issuer terms, merchant help pages, regulator notices); and structured reader reports, which we re-verify before publishing. When something is genuinely uncertain, we say so rather than guessing — “confirm with a small charge before you rely on it” is a real answer, not a hedge.
What we will not do
- We don’t help with sanctions violations, merchant fraud, or deceiving a platform’s risk checks.
- We don’t teach region-spoofing to dodge legitimate pricing.
- We don’t give investment advice or predict cryptocurrency prices. Stablecoins appear here only as a short-lived dollar bridge for funding a card.
- We don’t impersonate any brand, and we’re not affiliated with OpenAI, Valve, Google, or Meta.
Independence and money
These English pages carry the invite code OK6698 on the home page and two promotion links, one in the body of the Nigeria page and one in the body of the Türkiye page, each next to a line explaining it. There are no links in the navigation, the footer or any list page, and never more than one on a page. If you use the code or the link we may earn a commission and you normally don’t pay more — and it never changes page content. We name a service only where naming it makes the page more useful, and you can always type the code in on that service’s own site instead. The reasoning is set out in full on our disclosure page.
Found something wrong? Tell us
Rules change and we miss things. If an entry is out of date or a route stopped working, email gzs30@dollarferry.com with the service, your country, and what happened. We re-check, update the date, and credit useful corrections.
