Key Takeways
According to a report, the cybercrime cost is predicted to reach $9.5 trillion in 2024.
Unexpected verification codes, sent via text or email, are meant to add security by confirming your identity. But if you get one without trying to log in, it could mean someone else is trying to access your account. Cybercriminals use various tactics to steal data hence, you must act swiftly to protect your information.
How Serious is Receiving an Unrequested Verification Code?
The seriousness of an unexpected verification code depends on the account. Codes for non-sensitive accounts (like streaming) may not be urgent.
A code for a banking or financial account is a major red flag. If you get a bank code without trying to log in, it could mean a hacker has your details. They may have gained access through phishing or a data breach. Immediately contact your bank using official channels to confirm the code and secure your account.

How can you handle Unauthorized Account Creation?
Here’s how you can handle and manage unauthorized account creation
Stay Alert for Unrequested Codes
If you receive OTP SMS verification codes for accounts you didn’t create, it may indicate someone is using your contact info without your permission.
Recognize the Risks
This situation might seem harmless at first, but acting quickly is crucial to protect your personal information.
Gather Information
Take note of the verification codes and any details about the unauthorized account for your records.
Contact the Service Provider
Reach out to the company that sent the verification code. Use their official website or customer service number to ensure you’re contacting the right place. In some cases, it will be the OTP service provider and in others, it will be the business you are dealing with.
Verify Your Identity
Be prepared to prove your identity. This may involve answering security questions or providing identification.
Request Account Closure or Transfer
Ask the service provider to close the unauthorized account or transfer it to your control.
Document Your Communication
Keep records of your interactions with the service provider, including dates, times and names of representatives you spoke with.
Monitor for Spam
Keep an eye on your email and messages for any unwanted notifications or spam that may result from the unauthorized account.
Change Your Passwords
If you suspect that your information was compromised, change your passwords for other accounts, especially those linked to the same email or phone number.
Be Proactive About Security
Consider enabling two-factor authentication on your important accounts to add an extra layer of security and reduce the chances of unauthorized access in the future.
Monitoring for Data Breaches
Sometimes, an unexpected verification code can mean your personal info was exposed in a data breach. Cybercriminals use stolen login details to try accessing accounts.
To protect yourself, regularly check trusted cybersecurity sites that track data breaches. By entering your email or phone number, you can see if your info was compromised and take steps like changing passwords or watching for suspicious account activity.

Avoid Clicking Suspicious Links

Verify Requests Independently

For Businesses: Preventing OTP Fraud and Unauthorized Verification Requests
The flip side of this problem sits on your side of the exchange. When your signup, login, or checkout flow sends a one-time passcode, fraudsters and bots can trigger that same flow thousands of times against numbers that never asked for anything, an abuse pattern known as OTP fraud or SMS toll fraud. Every message you send is billed to your account, and the sudden volume spike gets flagged by carriers as suspicious traffic, which drags down deliverability for your legitimate customers too.
How to Prevent OTP Fraud and Unauthorized Verification Requests
- Verify phone numbers before sending an OTP. A quick pre-flight check through a phone number verification API filters out disposable, VoIP, and fraud-linked numbers before you spend on delivery
- .Rate-limit and fingerprint verification requests. Cap how many OTPs a single number or IP address can request per hour, and route delivery through an SMS verification API built to catch abusive request patterns.
- Add WhatsApp OTP as a fraud-resistant channel. WhatsApp delivery runs on TLS-secured IP rather than the open SMS network, so it is far less attractive for toll-fraud abuse and typically costs less per verified OTP.
- Route through a provider with built-in abuse detection. VerifyNow combines phone verification, adaptive rate limiting, and multi-channel delivery so a single fraud spike does not break your authentication flow or your budget.

Frequently Asked Questions
Why am I receiving a verification code I didn't request?
This usually happens when someone enters your phone number by mistake, or when someone tries to log in to an account using your number and the service sends an OTP to verify the attempt. It can also happen when automated bots target signup forms and trigger OTP messages to random or scraped phone numbers.
Is it safe to ignore an unrequested verification code?
Yes, as long as you never share the code with anyone and don't click any links in the message. The code alone cannot be used to access an account without also knowing your password, so ignoring or deleting the message is generally safe.
How can businesses stop sending OTPs to people who never requested them?
Businesses can prevent this by verifying phone numbers before sending an OTP, rate-limiting verification requests per number and IP address, and routing OTP delivery through a provider with built-in fraud detection such as Message Central's VerifyNow.
