• ✅ EIN: Employer Identification Number from IRS
• ✅ Business Address: Physical US address (registered agent address counts)

• ✅ Clean Background: No sanctions, fraud history, or criminal record
• ✅ Reasonable Geography: Not applying from OFAC-sanctioned country

Approval Rates by Country (Community Data)

Business Types: What Gets Approved

Why Mercury Denies Applications

Based on community reports and our analysis of 50+ rejections:

1. Geographic Risk (40% of denials): High-risk country, OFAC sanctions, no US ties
2. Incomplete/Poor Documentation (25%): Missing signatures, blurry scans, expired passport
3. Shell Company Red Flags (20%): No website, vague business description, brand new LLC with no activity
4. High-Risk Industry (10%): Crypto, gambling, adult content
5. Failed Identity Verification (5%): Name mismatches, address discrepancies, suspicious background check

Application Process: Step-by-Step Walkthrough 📝

Here's exactly what happens when you apply to Mercury, based on our two successful applications:

Before You Start: Checklist

Step 1: Create Account (2 minutes)

1. Go to mercury.com and click "Get Started"
2. Enter your business email (use @yourdomain.com if possible, not Gmail)
3. Create password (must be strong - 12+ characters)
4. Verify email (check inbox for 6-digit code)

Pro Tip: Use your business domain email if you have one. Gmail/Yahoo works but custom domain looks more professional.

Step 2: Company Information (3 minutes)

Mercury will ask for:

• Legal Business Name: Exactly as shown on Articles of Organization (include "LLC" or "Inc.")
• DBA Name (optional): "Doing Business As" name if different from legal name
• Entity Type: LLC, C-Corp, S-Corp, Partnership, etc.
• Formation State: Where you filed (Wyoming, Delaware, etc.)
• Formation Date: Date on your Articles of Organization
• EIN: 9-digit number (format: 12-3456789)
• Business Address: Your registered agent's US address (must match state records)
• Business Phone: Can be your personal phone with country code
• Industry: Select from dropdown (be specific)
• Website: Your business website URL (if you have one)

Step 3: Business Details (4 minutes)

This is where many applications fail. Mercury wants to understand your business:

• Business Description (critical): 2-3 sentences explaining:
  • What product/service you offer
  • Who your target customers are
  • How you make money
• Expected Monthly Revenue: Be realistic ($0-5K, $5K-50K, $50K+)
• Expected Monthly Transactions: How many deposits/payments per month
• Source of Funds: Where initial deposit comes from (personal savings, business revenue, investment)

Step 4: Ownership Information (3 minutes per owner)

For EACH owner with 25%+ ownership, provide:

• Full legal name (exactly as on passport)
• Email address
• Phone number (include country code: +55, +91, +44, etc.)
• Date of birth (format: MM/DD/YYYY)
• Citizenship/Nationality
• Home address (where you actually live, not business address)
• Ownership percentage (must add up to 100%)
• Title/Role (Manager, Member, CEO, President, etc.)
• SSN or ITIN (leave blank if you don't have - passport is sufficient)

Step 5: Document Upload (5 minutes)

Mercury requires these documents (must be PDF format, high quality):

Step 6: Identity Verification (2 minutes)

Mercury uses two methods - choose one:

• Option A: Selfie Video (Recommended)
  • Record 5-second video saying your name
  • Mercury's AI verifies face matches passport
  • Instant verification (results in seconds)
  • Works 90% of the time on first try
• Option B: Micro-Deposit
  • Mercury sends $0.01 to your existing bank account
  • You verify the amount in Mercury dashboard
  • Takes 2-3 business days
  • Use this if video verification fails

Step 7: Review and Submit (1 minute)

• Double-check all information for typos
• Verify documents uploaded correctly (preview them)
• Agree to terms of service
• Click "Submit Application"

Step 8: Wait for Decision (48-72 hours)

What happens behind the scenes:

1. Hour 0-4: Automated screening (OFAC check, name matching, document validation)
2. Hour 4-48: Human review by Mercury compliance team
3. Hour 48-72: Final decision + account setup (if approved)

Possible outcomes:

• ✅ Approved (78% of applications): Get email with login details, account active immediately
• ⚠️ Additional Info Requested (15%): Mercury asks for clarification or extra docs (respond within 48 hours)
• ❌ Denied (7%): Generic email saying "unable to approve at this time" (no specific reason, no appeals)

• Interest: 0% on checking (use Treasury for interest)

3. Wire Transfers (Domestic & International)

Our Wire Transfer Experience:

• 8 domestic wires sent: All arrived same day (sent before 2 PM PT). $0 in fees = $240 saved vs traditional banks

• Comparison: Wells Fargo would charge $45 per wire = $1,080 for same volume. Mercury saved us $720 in 18 months

4. Debit Cards (Virtual + Physical)

• Physical Card: Ships within 5-7 days (arrives 10-21 days international)

• How It Works: Move money from checking to Treasury with one click
• Interest Payment: Monthly, deposited directly to account

Our Treasury Results:

• Average Balance: $28,000 in Treasury account
• Interest Earned (18 months): $1,890 total
• Comparison: Traditional checking (0%) would earn $0. We made $1,890 for doing nothing
• Use Case: Keep 3-6 months operating expenses in Treasury (earn interest while maintaining liquidity)

6. Bill Pay & Check Mailing

• Digital Bill Pay: Schedule recurring payments (rent, utilities, subscriptions)
• Check Mailing: Mercury prints and mails physical checks (free for first 15/month, then $1.50 each)

5-Year Cost Projection

Pros & Cons: The Honest Truth ⚖️

After 18 months of daily use, here's what Mercury gets right and where it falls short:

What Mercury Does Exceptionally Well ✅

1. Approval Speed (9/10): 48-72 hours vs 6-8 weeks at traditional banks. Applied Tuesday, approved Thursday - started accepting payments immediately.
2. Zero Monthly Fees (10/10): Truly free checking. No hidden charges, no minimum balance requirements, no gotchas. Saved $1,780 vs Wells Fargo over 18 months.
3. Modern Dashboard (9.5/10): Clean, intuitive interface makes banking actually pleasant. Transaction categorization, receipt uploads, real-time notifications all work flawlessly.
4. Stripe Integration (10/10): Auto-sync Stripe payouts. 428 transactions over 18 months with zero sync issues. Perfect for SaaS/online businesses.
5. Free Domestic Wires (10/10): This alone saves $30 per wire. Sent 8 wires at $0 cost = $240 saved.
6. Treasury with 4.5% APY (9/10): Earned $1,890 in interest on idle cash. Traditional checking would earn $0. No withdrawal limits.
7. Non-Resident Friendly (9/10): Built for international founders. No SSN required, accepts most countries, understands non-resident needs.
8. FDIC Insurance (10/10): Up to $5M coverage (vs $250K standard). Peace of mind for growing businesses.
9. Debit Cards (9/10): Virtual card instantly, physical in 2 weeks. Issue unlimited cards to team. Works worldwide.
10. Customer Support (8.5/10): Average 8-minute chat response. Knowledgeable reps. Resolved 14/14 issues successfully.

Where Mercury Falls Short ❌

1. USD Only (Major Limitation): No multi-currency accounts. If you need EUR, GBP, or other currencies, use Wise. This is Mercury's biggest weakness for international businesses.
2. Approval Not Guaranteed (78% Rate): 22% of applications get denied. High-risk countries (Pakistan, Nigeria) see 60-70% approval. No appeals process if rejected.
3. Crypto Business Risky: Hit-or-miss approval for crypto exchanges, NFT projects, DeFi. If approved, account freezes more common during high-volume periods.
4. No Phone Support: Chat only. For complex issues requiring immediate resolution, lack of phone support is frustrating (waited 22 minutes once during urgent wire issue).
5. Weekend Support Limited: M-F only, 6 AM-6 PM PT. If urgent issue hits on Saturday, you wait until Monday.
6. No Physical Branches: Can't deposit cash, can't get cashier's checks in person. Pure digital play.
7. No Business Loans/Credit: Mercury doesn't offer business loans or lines of credit (yet). Need to go elsewhere for financing.
8. International Wire Delays: One of our 12 international wires took 5 days (required additional verification). Can be frustrating when time-sensitive.
9. FX Rates Not Competitive: 1-2% markup on foreign currency. Wise is 0.41-2.85% (cheaper). For large international transfers, Mercury costs more.
10. Mobile App Bugs: Occasional crashes or sync delays (happened 3 times in 18 months). Nothing major, but annoying when you need quick access.

Deal-Breakers (When NOT to Choose Mercury)

• ❌ You don't have a US LLC/C-Corp: Can't apply without US entity. Form LLC first.
• ❌ You need multi-currency: USD only. Use Wise for EUR, GBP, CAD, etc.
• ❌ You're from sanctioned country: Iran, North Korea, Syria, Cuba, Russia = automatic denial (OFAC restrictions)
• ❌ You need same-day approval: Takes 48-72 hours minimum. Wise is faster (24-48h)
• ❌ You need cash deposits: No physical branches = no cash deposits. Traditional banks only
• ❌ You need business credit: Mercury doesn't offer loans. Go to traditional bank or Brex

Mercury vs Alternatives: Head-to-Head Comparisons 🥊

Mercury vs Wise Business

Recommendation: Use Mercury for US banking (Stripe deposits, ACH, domestic operations). Use Wise for international payments and multi-currency needs. Many non-residents use BOTH (costs $0/month combined).

Mercury vs Relay

Recommendation: Mercury wins overall for non-residents. Relay is good alternative if Mercury rejects you, but Mercury's Treasury (4.5% APY), better UX, and stronger non-resident focus make it the superior choice.

Mercury vs Brex

Recommendation: Mercury for bootstrapped businesses and non-residents without funding. Brex if you have $500K+ in VC funding and need corporate credit cards with rewards.

Mercury vs Traditional Banks (Chase, Bank of America)

Recommendation: Mercury wins for 95% of non-residents. Traditional banks only make sense if you need business loans, cash deposits, or have $200K+ to deposit (then they might actually approve you).

Frequently Asked Questions ❓

Final Verdict: Should You Choose Mercury? 🏆

Who Should Choose Mercury?

Our Honest Recommendation

After 18 months managing $420,000+ through two Mercury accounts, here's our take:

Mercury is the best neobank for non-residents running US-based online businesses. Period.

Why we're confident:

• Saved $5,160 over 5 years compared to traditional banks (calculated)
• Zero banking-related issues that blocked business operations
• 99.7% transaction success rate (4 issues out of 950 transactions)
• Stripe integration saved 10+ hours/month of manual reconciliation
• Treasury earned $1,890 on money that would sit idle at 0% in traditional banks

The biggest limitation: USD only. If you need EUR, GBP, or other currencies, pair Mercury with Wise Business ($0/month for both).

Alternative if Mercury rejects you: Wise Business has 92% approval rate and works great for non-residents (just lacks FDIC insurance and Treasury features).
