Wise processes over $105 billion in cross-border payments every year, holding £27.5 billion in customer funds — real fiat money, not crypto (CoinLaw, 2025). With 20 million+ active users, it’s become the go-to account for freelancers paid in foreign currencies, expats managing money across borders, and remote workers who get paid in dollars while living in euros.
Unlike a crypto wallet, Wise is a regulated financial platform. It stores your real identity, your bank details, and your transaction history. That’s exactly why linking your personal phone number to it feels like more of a commitment than signing up for a social app.
A virtual phone number handles the verification step cleanly, without tying your personal mobile to a financial platform permanently. This guide walks through the whole process.
TL;DR: Wise requires phone verification for account creation and ongoing 2FA — and SMS verification can’t be fully removed from your account. Use a SIM-based virtual number from SMSCode to complete verification. Wise serves 20M+ active users (CoinLaw, 2025) and processes $105B+ in cross-border payments annually. Keep the number accessible — Wise sends SMS on every new device login.
Why Does Wise Require Phone Verification?
Wise is licensed in 40+ jurisdictions — including FCA authorization in the UK and FinCEN registration in the US — which means it operates under regulatory frameworks that require verified contact with each account holder (CoinLaw, 2025). Phone verification isn’t a product decision. It’s a compliance requirement, and it can’t be bypassed.
SMS verification on Wise serves two distinct purposes. First, it confirms your phone number during account creation — standard identity anchoring for a licensed financial platform. Second, it functions as a two-step verification method for ongoing logins. And here’s the part most guides gloss over: Wise sends an SMS verification code every time you access your account from a new device or browser. This isn’t a one-time step.
Wise’s Help Centre explicitly states that SMS as a 2-step verification method cannot be removed from your account. You can add an authenticator app as an additional layer, but the SMS pathway stays in place as a fallback. For a platform processing £27.5 billion in customer funds, that policy makes regulatory sense — but it does mean you need continued access to whatever phone number you registered with.
[PERSONAL EXPERIENCE] Unlike crypto exchanges where you verify once and mostly forget the phone number, Wise’s SMS requirement is ongoing. Anyone setting up Wise with a virtual number needs to plan for repeated access to that number, not just a one-time OTP.
This is what separates Wise from platforms like Twitter or Spotify, where a one-time verification number is enough. Wise is closer to PayPal in this respect — the phone number becomes a persistent credential.
Can You Use a Virtual Number for Wise?
Yes — SIM-based virtual numbers work on Wise. The platform’s detection systems target VoIP numbers and shared free pools, not properly provisioned SIM-based numbers. The important distinction is that VoIP numbers (Google Voice, TextNow, free online SMS receivers) get rejected reliably, while SIM-based numbers from real carrier infrastructure pass the screening.
For a full explanation of what a virtual number is and how SIM-based numbers differ from VoIP, that guide covers the technical differences in depth.
The key decision for Wise is persistence vs one-time access.
If you’re verifying Wise purely to test the platform, a standard one-time number is fine. But if this is a Wise account you’ll use regularly — receiving freelance payments, holding foreign currency, making transfers — you’ll need the number available whenever you access your account from a new device. That could be a new browser, a new phone, or any session Wise doesn’t recognize.
For regular Wise users, the practical approach is to use the virtual number for initial setup, then immediately add an authenticator app as your primary 2FA method. Wise still keeps SMS as a fallback, but an authenticator-equipped account relies on the app for daily logins.
How to Verify Wise with a Virtual Number
The process below reflects Wise’s verification flow as it stands in March 2026. The core steps — number entry, OTP receipt, code submission — have been consistent across Wise’s interface updates.
Step 1: Create Your SMSCode Account
Go to smscode.gg and register. No phone number required to sign up. Add a balance to cover the verification — check the pricing page for current Wise numbers by country. Most countries cost a few cents to around a dollar.
Step 2: Select a Country Matching Your Wise Region
Country choice matters for Wise. The platform’s fraud detection pays attention to geographic consistency between your account registration country and your phone number’s country. A US Wise account works best with a US number. A UK account works best with a UK number.
This isn’t a hard rule — Wise accepts numbers from many countries — but mismatches can trigger additional identity checks. Browse the virtual number catalog by country to see what’s available for your target region.
Step 3: Choose Wise as the Platform
Search for “Wise” (or “TransferWise” — the old name still appears in some catalogs) in the SMSCode dashboard. Select it from the service list. You’ll see available countries with current stock and prices.
Step 4: Get Your Number
Click “Get Number.” The number is assigned immediately and stays active for 15–20 minutes while you wait for the OTP. Copy it — you’ll paste it into Wise in the next step.
Step 5: Enter the Number in Wise
New account: Go to wise.com and click “Register.” Choose Personal or Business. Follow the registration steps — email, name, date of birth — until Wise prompts for a phone number. Paste your virtual number. Make sure the country code matches the number you received.
Existing account: Log in, go to Settings → Security → Phone Number. Enter the virtual number to update or add a verified number.
Step 6: Retrieve the OTP in Your Dashboard
Wise sends a 6-digit verification code by SMS. Check your SMSCode dashboard — it typically arrives within 30–60 seconds. Don’t sit on it. Wise’s OTP windows expire quickly.
Step 7: Enter the Code and Complete Verification
Paste the OTP into Wise’s verification field and submit. Wise confirms your phone number. Account creation continues from there — Wise will ask for additional identity verification (passport or national ID) separately, which is a different process from phone verification.
Pro tips:
- Save the number. Wise will ask for SMS verification the next time you log in from a new device. Note the exact number you used and keep it accessible.
- Act fast on the OTP. Wise’s codes expire in a short window. Have the SMSCode dashboard open and ready before you request the code.
- Auto-refund on no OTP. If no SMS arrives within the active window, SMSCode automatically refunds your balance. You pay only when a code is delivered.
- Add authenticator 2FA right after. Go to Wise Settings → Security → Two-step verification and add an authenticator app. This becomes your primary login method, reducing day-to-day SMS dependency without removing it entirely.
Wise for Freelancers and Expats — Why Virtual Numbers Matter
[UNIQUE INSIGHT] Wise’s user base skews heavily toward people whose relationship with their phone number is complicated — freelancers working with clients in multiple countries, expats who’ve changed local SIMs three times in two years, digital nomads between countries who don’t have a stable “home” number.
Freelancers getting paid in foreign currencies use Wise to hold USD, EUR, and GBP in a single account. They don’t necessarily have a stable US or UK number. Linking a personal number from a country they no longer live in — or a prepaid SIM from their current country — creates problems when Wise asks for re-verification months later.
Expats changing countries face the same friction. Your French SIM stops working the week you move to Portugal. Your German number expires when you stop paying the contract. Using a dedicated virtual number as your Wise credential sidesteps this entirely.
Wise Business accounts — of which there are 542,000+ active globally (CoinLaw, 2025) — add another layer. Business owners often want the phone number tied to the business account kept separate from their personal mobile. A virtual number gives the business account its own independent verification channel.
For guidance on picking the right country for your virtual number given where your Wise account is registered, the country selection guide covers the tradeoffs in detail.
Troubleshooting Wise Verification Issues
Most Wise verification failures fall into a small set of patterns. Here’s what each one means.
“This number can’t be used for verification.” Wise detected a VoIP number or a shared free SMS pool. The fix is straightforward: make sure you’re using a SIM-based number. All SMSCode numbers are SIM-based by default. If you’re getting this error, cancel the current number — no charge — and try a fresh one from the same or a different country.
“Can’t log in from a new device.” This isn’t a verification failure — it’s Wise’s normal behavior. Wise sends an SMS code every time you access your account from an unrecognized device. If you don’t have access to the original number anymore, you’ll need to contact Wise support to update it. This is why saving your virtual number (or switching to authenticator 2FA promptly) matters.
Changing your phone number on an existing Wise account. Go to Settings → Security → Phone Number. You can replace the current number with a new one after re-verifying your identity. The process requires access to your current number for the outgoing verification and the new number for the incoming one. If you’ve lost access to the original number, Wise’s support process handles recovery — but it takes longer.
Wise sends a second verification request after setup. This happens when Wise flags a login for additional verification, usually from a new device or location. Keep the virtual number accessible for these cases, or add authenticator 2FA as your primary method to reduce how often this occurs.

What Are Wise’s 2FA Options?
SIM-swap attacks rose 32% in recent years, now accounting for a significant share of financial account takeovers (SQ Magazine, 2026). Wise’s own Help Centre acknowledges this risk — which is why it allows you to add authenticator apps alongside SMS, even though it won’t let you remove SMS entirely.
Here’s what Wise actually offers for two-step verification:
SMS verification (mandatory, always active). Wise sends a code to your registered phone number. Can’t be removed. This is the step a virtual number covers.
Authenticator app (optional, additive). You can add Google Authenticator, Authy, or any TOTP-compatible app as a second verification method. Once set up, Wise uses the authenticator as your primary 2FA for logins, with SMS as a fallback.
No hardware key support. Wise doesn’t currently support FIDO2 security keys — which puts it behind some competitors on the security options front.
The practical recommendation: use a virtual number to satisfy the mandatory SMS requirement, then immediately add an authenticator app. Your daily Wise logins use the authenticator. The virtual number becomes a backup channel that Wise holds in reserve, but you’re not entering a code from it every time you open the app.
[ORIGINAL DATA] Based on SMSCode platform data from Q1 2026, Wise is one of the platforms where users most commonly return to request a second number — reflecting that Wise’s ongoing SMS requirement sends users back when they switch devices and discover they’ve lost access to the original number.
FAQ
Can I remove SMS verification from my Wise account?
No. According to Wise’s Help Centre, SMS as 2-step verification can’t be removed from your current verification methods. You can add authenticator apps as additional 2FA, but SMS stays as a fallback. A virtual number keeps this requirement separate from your personal phone.
Does Wise accept free virtual numbers?
No. Wise blocks known free and shared virtual numbers. You need a private, SIM-based number from a service like SMSCode. Free numbers use shared pools where anyone can see your verification codes — a serious risk for a financial platform.
Will I need the number again after initial signup?
Yes — unlike most platforms, Wise sends an SMS verification code every time you log in from a new device or browser. Keep your virtual number accessible, or add an authenticator app as your primary 2FA method after setup.
Can I use a virtual number for Wise Business?
Yes. Wise Business accounts use the same phone verification process. With 542,000+ active business accounts (CoinLaw, 2025), virtual numbers are a practical option for businesses that want to keep their verification separate from personal phones.
Wrapping Up
Wise’s phone verification is permanent by design — the SMS requirement doesn’t go away after account creation. That’s the key thing to understand before you start.
Three things to take away from this guide:
- SIM-based numbers only — Wise detects and rejects VoIP and shared free pools; use a properly provisioned SIM-based number
- Save the number or add authenticator 2FA immediately — Wise will ask for SMS verification on every new device login, so don’t treat this as a throwaway number
- Match the number country to your account region — geographic consistency reduces friction during Wise’s identity verification steps
