Independent editorial. No affiliate links, no pay-to-rank. Every fact here comes from our full reviews of Mercury and Relay, verified as of August 2026. Provider policies change monthly.
For most people reading this, the comparison is already over before it starts.
Relay requires an SSN or ITIN. Mercury doesn't. If you're a non-resident with a Wyoming LLC, an EIN and a passport — the standard setup — Relay is a closed door and Mercury is your application. Everything below is the detail behind that sentence, and the cases where it doesn't hold.

1. The decision, by situation
| If you… | Choose |
|---|---|
| Have no SSN and no ITIN | Mercury — Relay will decline you |
| Have an ITIN and a real US address | Relay is worth considering |
| Only have a registered agent's address | Neither — both reject it |
| Are resident in Pakistan | Neither — Mercury and Relay both restrict it |
| Are resident in Nigeria, Bangladesh, the Philippines, Indonesia or Vietnam | Not Mercury — check Relay's list separately |
| Run everything through QuickBooks or Xero | Relay, if you qualify |
| Send frequent international wires | Mercury — free outgoing wires |
| Want Profit First-style allocations | Relay — 20 accounts, 50 cards |
| Are pre-launch with no website | Neither yet — build the site first |
2. Eligibility — the only section that matters first
Fees are irrelevant if the door is shut. So this comes first.
| Mercury | Relay | |
|---|---|---|
| SSN or ITIN required | No | Yes |
| Physical US address required | Yes | Yes |
| Registered agent address accepted | No | No |
| Virtual mailbox accepted | No | No |
| Prohibited countries published | Yes, on their support site | Not prominently |
The ITIN gate is the whole comparison
Relay used to sit alongside Mercury as a standard non-resident recommendation. That changed quietly across 2024–2026, and most published reviews still haven't caught up. Relay now requires an SSN or ITIN for the account holder.
For a founder whose entire US footprint is an LLC, an EIN and a passport, that requirement is disqualifying. No amount of application polish changes it.
Don't get an ITIN purely to open a Relay account. If you already have a US tax filing obligation — a 1040-NR, treaty benefits, US-source income — you may need one anyway, and Relay access is then a genuine bonus. But acquiring one solely for banking rarely justifies the cost and processing time when Mercury is open to you.
Both reject the same address
This one catches people who did everything else right. Neither provider accepts a registered agent's address or a virtual mailbox as a business address.
Mercury's address checks flag commercial mail-receiving agencies, which is how most virtual mailbox providers are registered. Relay rejects PO boxes, virtual mailboxes and Pack & Ship addresses outright — and the frustrating part is that its form accepts the address without complaint, so founders often learn this only after being declined.
If you don't have a genuine US address, solve that before applying to either.
Country restrictions are maintained separately
Mercury publishes its prohibited list. Per Mercury's own support documentation it includes Bangladesh, Indonesia, Nigeria, Pakistan, the Philippines, Ukraine, Vietnam and others. Mercury's co-founder announced the 2024 additions publicly, attributing them to a stricter regulatory environment and strain on partner banks.
Relay does not publish its list prominently. Pakistan is confirmed restricted — and an ITIN does not help there.
Do not assume the two lists match. They are maintained separately by two different companies with two different partner banks. A country closed at Mercury is not necessarily closed at Relay, and the reverse is also true.
Check before you rely on this: both lists move. Verify on each provider's own support pages before applying.
3. Fees and structure
Neither is expensive. They're built differently.
| Mercury | Relay | |
|---|---|---|
| Monthly fee | None | None |
| Minimum balance | None | None |
| Incoming wires | Free | Free |
| Outgoing wires | Free, domestic and international | Not stated in our review |
| FDIC coverage | Reported around $5M via sweep | Reported up to $3M via Thread Bank sweep |
| Partner banks | Choice Financial Group, Column N.A. | Thread Bank |
| Sub-accounts | Standard | 20 checking accounts, 50 debit cards |
| Cash deposits | — | Not supported |
| Check writing | — | Not supported |
| Check deposit holds | — | 6–7 business days reported |
Check before you rely on this: FDIC coverage figures and partner bank relationships change. Verify current limits with each provider.
Free outgoing international wires is Mercury's most underrated advantage for this audience. If you invoice clients abroad, that's a real recurring saving rather than a feature-list item.
Relay's twenty accounts are its most underrated advantage. For anyone running Profit First allocations, managing several revenue streams, or separating client funds from operating funds, there is no close substitute at this price point.
4. The freeze and shutdown difference
This section exists because no other comparison page has it, and because it's the difference that costs people money.
The two providers fail in different places.
Mercury's risk is mid-life. The documented pattern: account approved normally, business operates for weeks or months, a KYC refresh or a location signal triggers review, account closed citing terms without specifics, balance held — commonly reported around 60 calendar days — and returned by paper check.
That paper cheque detail is close to disqualifying if you're in Lagos, Karachi or Manila with no US mailing address, and it's rarely mentioned in reviews written for a US audience.
Mercury has stated the mechanism plainly: decisions rest on business and residential addresses given during onboarding and KYC refreshes, plus frequent location of account activity via IP address.
Relay's risk is at the front door. The honest position is that Relay's post-onboarding freeze pattern is far less documented — and the reason is that far fewer non-residents get through the application in the first place. Fewer accounts means fewer complaint threads.
So the practical difference: most non-resident pain at Relay is a decline. Most non-resident pain at Mercury is an offboarding. A decline costs you an afternoon. An offboarding costs you your operating balance for two months.
We're not going to manufacture a Relay pattern to match Mercury's. The data is thin, and saying so is more useful than inventing symmetry.
The rule that applies to both
Never keep your full balance in a single fintech.
This is not a criticism of either provider. It's the structural reality of banking through a fintech as a non-resident — a compliance decision can lock your operating capital with little warning and no useful appeal. The founders who survive it run two rails and sweep surplus out weekly.
5. Accounting integrations
Relay wins this outright, and it's why accountants recommend it.
QuickBooks integration is the deepest in the category. Xero is equally strong. Gusto and Expensify are well supported. If your business reconciles through QuickBooks and you want banking that doesn't fight it, Relay is the best-fitting product available.
Mercury's integrations are strong but differently aimed. Stripe works cleanly — Mercury account details function as a Stripe payout destination, which is the single most common stack for this audience. QuickBooks and Xero are native and well maintained. Shopify and Amazon work over standard ACH and wire.
If your stack is US LLC → Stripe → Mercury → accounting software, it fits together without friction.
6. What each one is genuinely best at
Mercury is best at being open. No tax ID requirement is the single most valuable property a US business bank can have for this audience, and it's why Mercury became the default recommendation. Add free international wires and the best product design in the category, and for a founder in a supported country it's hard to beat.
Relay is best at structure. Twenty accounts, fifty cards, the deepest QuickBooks integration available, and reported FDIC coverage up to $3M. For a founder who has cleared the ITIN and address hurdles and runs a business with real allocation needs, it's excellent.
They're not really competing for the same person. Mercury competes for everyone; Relay competes for the subset who already have a US tax identity.
7. When neither is right for you
If you're in a country Mercury prohibits and you don't have an ITIN, both doors are closed. That's a large share of the people reading this, and it isn't a dead end.
Wise Business is the most universally approvable option for this audience. It isn't a bank — it's an EMI, so no FDIC — but it has the broadest country acceptance and strong FX at roughly 0.4–0.6%. Expect enhanced KYC from Pakistan and Nigeria: more document requests, but the door is open.
Airwallex is the strongest multi-currency alternative, with good non-resident approval rates.
Payoneer is the practical receiving rail if marketplaces are your main income source.
A traditional bank account at Chase or Bank of America, opened in person if you'll eventually visit the US, is the most durable option available — and the least likely to be closed by an algorithm.
Our full rankings work through all of them, and the Country Path Checker will tell you which are open from where you are.
The honest bottom line
Mercury if you don't have a tax ID, you're in a supported country, and you have a real business with a real address. Which describes most people asking this question.
Relay if you already hold an ITIN for tax reasons, have a genuine US address, and want the accounting integration and multi-account structure.
Neither if your only US address is a registered agent's, or if you're in Pakistan.
And whichever you pick, open a second rail before you need it. The comparison that actually matters isn't Mercury versus Relay — it's one account versus two.
Should you pay someone to apply?
For either provider, no. Both applications are free, online and self-serve. There's no privileged channel and no partner relationship that guarantees approval — anyone claiming otherwise is describing something that doesn't exist.
What determines the outcome is your country, your tax ID, your address, your website and the consistency of your documents. All of which you control.
Where help genuinely earns its cost is upstream: knowing before you apply whether your country is eligible, solving the physical address problem properly, and getting an ITIN if you have a legitimate tax reason for one. That's preparation, not access.
