You hit send code on Mercari, and nothing. Crickets. That little SMS just never shows up.
Trust me, you're not alone. Thousands of people run into this every single day. And here's the thing it's probably not your fault. More often than not, Mercari's anti-spam system has silently flagged your number, or there's a routing delay somewhere in the chain.
This guide is for anyone trying to verify a Mercari account (US or JP) and dealing with OTP failures. Whether you're a buyer, seller, or power user, these fixes actually work in seconds. Just a heads-up don't use these methods for account recovery or payment verification. Mercari may need your real number for those sensitive actions.

If your code doesn't arrive in 60 seconds, cancel and retry with a different number from a different country pool.
Always match your IP address to your virtual number's country code using a VPN to avoid anti-spam filters.
Never refresh the Mercari app while waiting for an OTP it cancels the pending SMS.

#Why Your Mercari OTP Isn't Arriving Common Culprits You Can Fix Fast
Let's cut to the chase. Most Mercari OTP failures boil down to three things: a blocked number (someone else used it before you), a blocked SMS sender, or a simple network delay. Mercari's anti-spam filter is aggressive if your number looks even slightly suspicious, the app silently drops the SMS no error, no warning, just an empty inbox.
Mercari's fraud detection flags numbers that have received too many codes within a short period.
Many free or basic virtual numbers are already blocked in Mercari's database.
The airplane mode toggle and carrier reset can force the SMS gateway to reroute.
If you're using a non-US carrier internationally, SMS routing delays are common.
Mercari's anti-spam filter silently drops SMS codes from numbers with a high fraud score you get no error message, just an empty inbox.

#How to Troubleshoot Mercari SMS Code Problems on iPhone and Android
On both platforms, the process is nearly identical: you request the code, then check the Messages app (iPhone) or the default SMS app (Android). The most common mistake? Missing the code because it's hidden under Filtered Messages or your phone's spam folder. On Android, open the Messages app, tap the three dots, then Spam & blocked Mercari codes often land there.
iPhone: Go to Settings > Messages > Filter Unknown Senders and toggle off.
Android: Clear the Messages app cache under Settings > Apps > Messages > Storage.
If using a dual-SIM phone, ensure the data line matches the number you provided to Mercari.
Restarting the phone clears bugs in the SMS queue that cause code not received errors.

#Mercari Two-Factor Authentication Failed? Here's Your Step-by-Step Reset
If Mercari's 2FA is failing repeatedly, it means the app's session token for your number has gone stale. The fix requires resetting the full phone number in Mercari's security settings.
Go to Settings > Account > Security > Two-Factor Authentication.
Remove the current number from your account.
Wait 15 minutes this allows Mercari to clear the session cache.
Re-add the number using a fresh code from a new virtual line.
Do not reuse the same virtual number immediately Mercari caches failed requests for up to 6 hours.
If you see Too many requests, wait 24 hours before attempting again.
Using a number from a different country pool (e.g., Canada instead of the USA) can bypass IP-based blocks.
After reset, ensure your IP matches the number's region as much as possible.
#The Silent Killer of Mercari Verification: Carrier vs. Number Compatibility Issues
Not all virtual numbers are created equal. Mercari's backend uses carrier code parsing that rejects numbers from certain VoIP ranges or specific area codes. If your number's carrier is flagged as Google Voice or TextNow, Mercari will block the SMS every time. The workaround? Use numbers from real mobile carriers (like T-Mobile or AT&T) even when they're virtual.
Always check the carrier type before choosing a virtual number avoid VoIP/LCR tagged lines.
Numbers from major US carriers (T-Mobile, Verizon, AT&T) have the highest acceptance on Mercari.
Some providers let you filter by carrier; if not, test two different numbers from the same batch.
UK and Japan numbers often work better for Mercari-JP than US numbers for Mercari-US.
A number from a real mobile carrier like T-Mobile has a 95% success rate on Mercari, compared to less than 20% for a VoIP number.

Request a new number from a provider with direct carrier access, then immediately request the code from Mercari without switching apps.
The error is often a session timeout close the Mercari app completely, reopen, and try again.
If using a browser, clear cookies and cache before the second attempt.
Switching from Wi-Fi to cellular data can force a different SMS routing path.

The app's batch processing Mercari queues SMS sends every 60 seconds. If you're in a rush, request the code, wait 45 seconds, then cancel and request again. The second attempt often skips the queue.

#How to Avoid Mercari Phone Verification Failed Errors When Using Virtual Numbers
Phone verification failed is Mercari's catch-all error for numbers that look suspicious. The fix isn't in the number itself it's in the account setup. If the IP address you're using doesn't match the country code for the number, Mercari will flag the verification. Always use a VPN or proxy that matches the number's region before starting verification.
Verify the number from a browser on a computer to inspect IP-matching don't use mobile data.
If using a USA number, connect to a USA-based VPN server before opening Mercari.
Avoid using VPNs from free providers (Mercari blocks known VPN IP ranges).
Incognito mode or a fresh browser profile reduces the chance of cached session conflicts.
An IP mismatch is the #1 reason for Mercari phone verification failed errors when using an otherwise valid virtual number.
