broken.<\/span><\/p>\nHere’s the quick pass:<\/span><\/p>\n\n- Confirm what kind of code it is: <\/span>SMS, email, login prompt, or password reset<\/b><\/li>\n
- One request, wait <\/span>30\u201390s<\/b>, retry once<\/span><\/li>\n
- Switch <\/span>app web<\/b><\/li>\n
- Switch <\/span>Wi-Fi mobile data<\/b><\/li>\n
- Disable <\/span>VPN\/AdBlock<\/b> briefly<\/span><\/li>\n
- Still stuck? Use the official recovery flow rather than button-mashing.<\/span><\/li>\n<\/ul>\n
If you request five codes in 20 seconds, you didn’t try harder. You likely triggered a rate limit, and now you’re fighting <\/span>both<\/span><\/i> delivery and throttling.<\/span><\/p>\n<\/span>First, identify which code you’re missing<\/b>.<\/span><\/span><\/h2>\nOTP problems aren’t random; they’re channel-specific. <\/span>SMS<\/b> usually breaks because of carrier routing\/filtering. <\/span>Email<\/b> breaks because spam filter rules\/delays eat it. And <\/span>login\/password reset<\/b> flows break when your session is stale, or the wrong number\/email is on file.<\/span><\/p>\nUse this quick decision tree:<\/span><\/p>\n\n- Expected a <\/span>text<\/b>? Think signal, carrier filtering, blocked senders, and request limits.<\/span><\/li>\n
- Expected an <\/span>email<\/b>? Think spam\/trash, filters\/rules, provider delays.<\/span><\/li>\n
- Stuck on a <\/span>login screen<\/b> that keeps asking for a code? Think cookies, cached sessions, or VPN\/AdBlock interference.<\/span><\/li>\n
- Doing a <\/span>password reset<\/b>? Treat it like a high-friction flow, don’t spam retries.<\/span><\/li>\n<\/ul>\n
You’re not fixing Affirm. You’re figuring out which delivery lane is failing, then switching lanes.<\/span><\/p>\n<\/span>Affirm SMS code not received: fixes that actually work<\/b>.<\/span><\/span><\/h2>\nIf Affirm SMS codes aren’t showing up, fix the delivery chain first, signal, blocked senders, short-code filtering, and request limits, then retry once from a stable connection. Most of the time, it’s broken because the text never landed.<\/span><\/p>\nTry these in order:<\/span><\/p>\n\n- Toggle airplane mode reconnect\u00a0<\/span><\/li>\n
- Restart once\u00a0<\/span><\/li>\n
- Temporarily turn off SMS spam blockers or message cleaner apps<\/span><\/li>\n
- Check blocked numbers \/ unknown sender filters<\/span><\/li>\n
- Switch <\/span>Wi-Fi mobile data<\/b>, then request the code once more<\/span><\/li>\n
- If it keeps failing, stop looping and move to a more reliable verification plan<\/span><\/li>\n<\/ul>\n
If you’re not getting verification texts from multiple services, not just Affirm, that’s almost always carrier-side.<\/span><\/p>\nCarrier, signal, short-code filtering checks<\/b><\/h3>\n
A lot of OTP texts come via <\/span>short codes<\/b>, and carriers treat those differently from normal messages. So yes, you can get regular texts, fine, and still miss verification codes.<\/span><\/p>\nMini checklist:<\/span><\/p>\n\n- Stable signal?<\/span><\/li>\n
- Roaming or using a travel SIM?<\/span><\/li>\n
- Turned on aggressive spam protection recently?<\/span><\/li>\n
- Dual-SIM phone: set the correct SIM as the default for SMS?<\/span><\/li>\n
- Resent too many times and triggered throttling?<\/span><\/li>\n<\/ul>\n
My friends’ texts arrive, but OTPs don’t. That’s classic short-code filtering behavior.<\/span><\/p>\n![\"Affirm](\"https:\/\/pvapins.com\/blog\/wp-content\/uploads\/2026\/01\/Affirm-OTP-not-received-troubleshooting-checklist-for-SMS-email-and-login-code-issues.webp\")

iPhone: where missing OTP texts hide<\/b><\/h3>\n
On an iPhone, the message might not be missing; it might be <\/span>filtered<\/b>. iOS can route texts from unknown senders into a separate view.<\/span><\/p>\nCheck:<\/span><\/p>\n\n- Messages\u00a0 Filters <\/span>Unknown Senders<\/b><\/li>\n
- Blocked Contacts list<\/span><\/li>\n
- Focus \/ Do Not Disturb\u00a0<\/span><\/li>\n<\/ul>\n
Apple reference:<\/span><\/p>\nAndroid: permission default SMS app sanity check<\/b><\/h3>\n
Android issues are often dull, which is excellent, because boring is fixable.<\/span><\/p>\n\n- Confirm your default SMS app didn’t change after an update<\/span><\/li>\n
- Check permissions<\/span><\/li>\n
- Pause aggressive filtering apps temporarily<\/span><\/li>\n
- Retry once on a stable connection<\/span><\/li>\n<\/ul>\n
If you’re testing, test clean: one request, one wait, one retry.<\/span><\/p>\n
