If Mercari’s asking for a phone number and you don’t have one, yeah, that’s frustrating. Or maybe you do have a number, you don’t want it tied to your selling account, totally fair. Either way, this usually turns into one of those this should take 30 seconds tasks that suddenly eat up your whole afternoon.
In this guide, I’ll walk you through how to verify Mercari without a phone number in a practical, user-friendly way, what to try first, what to do if SMS is required, and how to fix the annoying errors that keep popping up.

Quick reality check: Does Mercari require SMS phone verification?
Short answer: yes, pretty often. Mercari uses phone verification to help confirm you’re a real person and to protect accounts from suspicious activity. In many situations, that means you’ll need an SMS verification code (OTP) to finish signup, log in, or complete specific account actions.
Here’s the critical nuance: without a phone number usually means without using your personal number, not skipping verification entirely. Depending on what Mercari is prompting you for, an SMS-capable number may still be required.
A quick mental model:
- Signup verification: common when creating a new account
- Login verification: common when signing in from a new device
- Recovery verification: standard when resetting access/security details
- Rate limits: too many retries can temporarily block codes
If you want the most accurate, up-to-date guidance for your exact flow, go straight to Mercari’s official Help Center. It’s the only place that reliably reflects what they currently require:
The safest no-personal-phone path: what you can do first
Do this first seriously. Many verification issues aren’t real issues. They’re formatting mistakes, permission hiccups, or the classic I tapped resend 10 times, and now it’s rate-limited situation.
Try this clean pass before you touch any virtual number:
- Confirm your email + basic account setup (if Mercari offers that step first)
- Check number formatting (country code, no extra spaces, no weird copy/paste artifacts)
- Update the app and restart your phone (annoying, but it works)
- Avoid rapid resends; too many attempts can trigger throttling
And if the reason you’re here is privacy, I get it. You’re not being dramatic; you don’t want your personal number floating around more places than it needs to.
The goal is to verify cleanly, not bypass anything.
Temporary numbers for SMS: what works, what’s risky
A temporary phone number for SMS can absolutely be a practical option when you don’t want to use your personal line. But not all temp numbers are created equal. Some are public, some are private-access, and some are great for one-time OTPs, while others are better if you’ll need repeat access later.
Here’s the deal: the stricter the platform is about number types, the more you’ll care about privacy and stability. For anything sensitive, shared inboxes are a gamble.
A few realities to keep you out of trouble:
- Some platforms filter certain number types (especially shared/public inboxes)
- Shared inboxes can reduce privacy (other people may see incoming texts)
- If you’ll need future logins or recovery codes, you want continuity, not a one-off

Public inbox vs private number access
A public inbox is basically a shared page where anyone can view incoming SMS messages. It’s fast, it’s easy, and it’s okay for low-stakes testing, but it’s not ideal for accounts you’ll rely on.
A private number access option means only you can view the incoming messages for that number (during your activation or rental period). That’s usually the more intelligent choice for:
- Account logins you may need again
- Recovery codes you really don’t want exposed
- Reducing the risk of message leakage
With PVAPins, you can start lightweight with Free Numbers, then move to more stable options as Mercari needs.
Free vs one-time activations vs rentals
If you only need one verification code once, keep it simple. One-time activations are often the cleanest path. But if you’ll need the number again (re-logins, recovery, repeat codes), rentals make more sense.
Here’s the simple breakdown:
- Free numbers: good for quick testing and low-stakes checks
- One-time activations: best when you need a single OTP, and you’re done
- Rentals: best when you need ongoing access later (login, recovery, repeat verification)
This is where PVAPins fits naturally: 200+ countries, privacy-friendly workflows, and options that can be a better fit than basic web-only number types when a platform is picky. If you care about reliability, private access is usually worth it.
Payment note (mentioned once, as promised): PVAPins supports multiple gateways, including Crypto, Binance Pay, Payeer, GCash, AmanPay, QIWI Wallet, Nigeria & South Africa cards, Skrill, and Payoneer.
Step-by-step: receiving a Mercari OTP with a virtual number
Here’s a clean, user-safe process:
- Pick a number type that matches your need
- Only need one OTP? Start with a one-time option. Should I need future access? Consider a rental.
- Request the code once
- Don’t hammer resend. OTP systems can lag a bit (especially during busy times).
- Retrieve the SMS code
- Use your receive/inbox view to grab the newest OTP and enter it right away.
- If it expires, request a fresh one once
- Multiple resends can invalidate older codes. Then you’re chasing ghosts.
If you want an easier, all-in-one place experience, PVAPins also has an Android app handy if you don’t want to juggle tabs while you’re trying to verify:

Mercari verification code not received: fast troubleshooting checklist.
If the code isn’t arriving, don’t assume it’s your fault. Most of the time, it’s deliverability, filtering, or throttling. The fix is to troubleshoot calmly and make one controlled change at a time.
Try this in order:
- Check connection and device settings: stable network, notifications on, permissions allowed
- Look for blocked senders or spam filtering: some phones hide OTPs quietly
- Stop resending repeatedly: wait, then request one new code
- Try a different number type if needed: shared/public inboxes may be filtered more often
- Only enter the latest code: older ones can be invalid or expired

Phone number already in use on Mercari, how to fix it
This error is annoyingly familiar. It usually means:
- The number is linked to another Mercari account, or
- The number was previously used for verification, or
- The number is recycled and still attached to Mercari’s system
Fastest fix: use a different number. Don’t brute-force it. Mercari may temporarily block attempts if you keep retrying.
What to do:
- Assume the number is attached somewhere already
- Try a fresh number instead of repeating attempts
- If you control the other account, update or remove the number there first
- If you can’t access the linked account, contact support with the exact error
This is one of those situations where rentals can help, as you can keep a consistent number for future logins and recovery.
Receive SMS on Wi-Fi: when it helps and when it doesn’t
Receive SMS on Wi-Fi can help if your real issue is a weak signal, roaming problems, or a phone that’s being weird about incoming messages.
But it won’t fix number-type restrictions. If a platform filters certain types of numbers, switching to Wi-Fi doesn’t magically change that.
Use Wi-Fi receiving when:
- You’re travelling or in a low-signal area
- You need steady access to retrieve the code
- Your device drops SMS notifications randomly
It won’t help much when:
- The platform is filtering the number type
- You’re rate-limited from too many resends
- The code you’re entering has already expired
One small tip that saves headaches: don’t flip VPNs or bounce networks mid-verification. Consistency helps.

Mercari SMS verification when travelling or in international scenarios
If you’re abroad, verification can get flaky for boring reasons: roaming, carrier filtering, or formatting mismatches. The fix is usually to simplify, not to complicate.
What usually goes wrong:
- Roaming is off, or messages arrive late
- The format doesn’t match what the form expects
- Switching locations/IPs triggers extra security checks
What to do instead:
- Choose a number option aligned with your account’s region expectations
- Keep the flow consistent, don’t switch numbers mid-process
- Prefer a stable option if you may need future logins or recovery

Security best practices for SMS verification protect your account.
Treat OTP codes like passwords. Don’t share them, don’t forward screenshots, and definitely don’t give them to anyone claiming to be support. Honestly, if someone asks for your OTP, that’s the whole red flag right there.
If you’re using a virtual number for privacy, private access helps reduce the risk of misuse in the shared inbox. And don’t skip the basics; your email security matters a lot because it often becomes the recovery key.
habits that actually help:
- Don’t share OTP codes ever
- Use a strong, unique password and secure your email account
- Be cautious of messages pretending to be support
- Keep recovery options updated and consistent

When to contact Mercari support
If you’ve tried clean retries and you’re still blocked, support is the most legitimate next step. The secret is giving them enough detail so you don’t get a generic reply.
Send this (short and specific):
- Exact error message
- Your country or region
- Approx time of attempts
- Device and OS version and app version
- What have you already tried
Also: don’t keep retrying verification while a ticket is open. That can create new blocks and make it harder for support to help.
FAQ
Q: Can you verify Mercari without a phone number at all?
A: In many cases, Mercari requires SMS verification for signup, login, or account actions. Without a phone number usually means not using your personal number, not skipping verification. Your options depend on what Mercari is prompting for.
Q: Why isn’t Mercari sending my verification code?
A: Common causes include carrier filtering, permission issues, unstable connections, or rate limits from repeated resends. Check settings first, then request a new code. Always enter the newest OTP.
Q: What phone number format should I use for Mercari verification?
A: Use the correct country code and avoid extra spaces or symbols. If you pasted the number, double-check you didn’t include hidden characters. Let the form auto-format if it does that.
Q: What’s better for Mercari: one-time activation or a rental number?
A: One-time activations fit a single OTP moment. Rentals are better if you’ll need future login or recovery codes. The deciding factor is whether you’ll need the number again later.
Q: Is it legal and safe to use a temporary number for verification?
A: It depends on Mercari’s terms and your local regulations. Use temporary numbers for legitimate privacy/account access needs, and avoid anything that violates policies. When in doubt, check official help documentation.
Q: What should I NOT use temporary numbers for?
A: Don’t use them for impersonation, policy violations, fraud, or anything illegal. Also, avoid public/shared inboxes for sensitive accounts, since messages can be viewable by others.
Q: What if I get a phone number already in use on Mercari?
A: That usually means the number is linked to another account or was used before. Try a different number instead of repeatedly retrying. If you can’t access the connected account, contact support with the exact error.
Conclusion
If Mercari asks for SMS verification, the goal isn’t to skip it; it’s to complete it safely without handing over your personal number. Start with the basics (formatting, settings, one controlled resend), then choose the option that matches your needs: quick testing, one-time verification, or ongoing access for re-logins and recovery.
