The newest code usually works better than the first delayed one.<\/span><\/li>\n<\/ul>\nAlso, switching networks helps more than people expect. If you’re on weak reception, roaming, or Wi-Fi calling is acting weird, SMS delivery can lag. A quick change (Wi-Fi or cellular) can unstick things.<\/span><\/p>\n<\/span>Fixes on iPhone: settings that block verification texts<\/b><\/span><\/h2>\nOn iPhone, OTP texts can get blocked by Focus modes, hidden by filters, or muted by notification settings.<\/span><\/p>\nTry these iPhone checks (in this order, trust me):<\/span><\/p>\n\n- Focus or Do Not Disturb:<\/b> Temporarily turn it off and retry.<\/span><\/li>\n
- Filter Unknown Senders:<\/b> OTPs may show up in a separate filtered list.<\/span><\/li>\n
- Message delivery mode:<\/b> OTPs are plain SMS, not iMessage. Make sure SMS works.<\/span><\/li>\n
- Date & time:<\/b> Set to automatic (Settings, General, Date & Time).<\/span><\/li>\n
- Restart Messages and reboot:<\/b> Annoying, yes. Still one of the best fixes.<\/span><\/li>\n<\/ul>\n
If you want a reliable reference point, Apple’s official guidance on <\/span>blocking and filtering Messages<\/b> is worth a quick read (support.apple.com).<\/span><\/p>\n<\/span>Fixes on Android: permissions, spam filters, and messaging apps<\/b><\/span><\/h2>\nAndroid phones often <\/span>receive<\/span><\/i> OTPs, but your SMS app flags them as spam or blocks short-code texts.<\/span><\/p>\nRun this checklist:<\/span><\/p>\n\n- Confirm your default SMS app and grant notification permissions.<\/span><\/li>\n
- Check the spam\/blocked folder inside the messaging app.<\/span><\/li>\n
- Temporarily turn off battery optimization for your SMS app (on some phones, delivery is delayed).<\/span><\/li>\n
- Use an official messaging app supported by your phone or carrier.<\/span><\/li>\n
- Restart and request a single fresh code.<\/span><\/li>\n<\/ul>\n
Android settings vary a ton by device, so where is spam?\u00a0 The question is fundamental. Google’s official help on <\/span>blocking and reporting spam texts can help you find the proper menus fast.<\/span><\/p>\n![\"Mercari](\"https:\/\/pvapins.com\/blog\/wp-content\/uploads\/2026\/02\/Mercari-OTP-not-received-error-on-phone-verification-screen.webp\")
<\/p>\n
<\/span>When Mercari says verification code not working: invalid or expired<\/b><\/span><\/h2>\nInvalid usually means you entered an older code.\u00a0 Expired means the SMS arrived late or you waited too long.<\/span><\/p>\nHere’s the clean reset:<\/span><\/p>\n\n- Stop requesting codes for a minute.<\/span><\/li>\n
- Close Mercari completely.<\/span><\/li>\n
- Wait briefly.<\/span><\/li>\n
- Open Mercari again and request <\/span>a<\/b> new code.<\/span><\/li>\n
- Enter the newest code you receive (ignore older late arrivals).<\/span><\/li>\n<\/ul>\n
If codes keep expiring:<\/span><\/p>\n\n- SMS delivery is probably delayed by filtering\/network issues.<\/span><\/li>\n
- You might be stuck in a resend loop, generating multiple codes.<\/span><\/li>\n<\/ul>\n
Also, watch for too many attempts.\u00a0 That’s your cue to stop. Honestly, pushing harder usually makes it worse.<\/span><\/p>\n<\/span>Mercari phone verification not working: number format and account checks<\/b>.<\/span><\/span><\/h2>\nSometimes it’s not delivery, it’s the number setup. Formatting errors, country code mismatches, or number conflicts can cause verification to fail.<\/span><\/p>\nCheck these:<\/span><\/p>\n\n- Enter your phone number exactly how Mercari requests (often with country code).<\/li>\n
- Watch for leading zeros and mismatched country selection.<\/li>\n
- If you see a phone number already in use, it may be tied to another account.<\/li>\n
- If you’re changing numbers, confirm your recovery options first.<\/li>\n
- Write down the exact error message. Support moves faster with specifics.<\/li>\n<\/ul>\n
This is also where people get stuck after switching carriers, moving from SIM to eSIM, or changing phones. Same number, different routing. It happens.<\/span><\/p>\n<\/span>Short-code SMS not received: carrier blocks and otp-in steps<\/b>.<\/span><\/span><\/h2>\nCarriers frequently filter short codes, which can prevent Mercari OTP texts from reaching your phone.<\/span><\/p>\nA <\/span>short code is a special automated texting number. Carriers treat them differently. Some accounts even have short codes blocked by default.<\/span><\/p>\nTry this:<\/span><\/p>\n
