Received a link verification code text out of nowhere? It usually means one of two things: either your phone number is saved with Stripe Link and someone triggered a checkout verification, or a service you use sent a one-time code because a login or password reset was attempted on your account.
Why Did You Receive a Link Verification Code Text?
The short answer: something — a login attempt, a password reset request, a checkout, or a simple typo by someone else — triggered an automated security message tied to your phone number.
Most of the time, it's harmless. Someone entered the wrong number during signup or checkout. The code expires in minutes and nothing happens.
But sometimes it signals something worth paying attention to — like someone actively trying to get into one of your accounts. The key is knowing which situation you're in.
What Is Stripe Link and Why Is It Texting You?
This is one of the more specific — and more confusing — reasons people receive these messages. Stripe Link is a payment tool built by Stripe that lets shoppers save their card and address details once, then reuse them across thousands of online stores without re-entering everything each time.
When you check out on a site that uses Stripe, Link may associate your phone number with your saved payment profile. Future checkouts on any Stripe-powered site can then trigger a verification text to confirm it's really you.
What If You Never Signed Up for Stripe Link?
This is where it gets confusing for a lot of people. You don't have to consciously "sign up" for Link. If you've ever completed a purchase on a Stripe-powered checkout and your phone number was entered, Link may have quietly saved your details.
Alternatively — and this happens more than you'd expect — someone else entered your phone number by mistake during their own checkout. One digit off, and the verification lands on your phone instead of theirs.
In either case, you are not at financial risk simply from receiving the text. The code itself doesn't expose any payment data.
How to Remove Your Data from Stripe Link
If you want the texts to stop, you can delete your saved payment information directly through Link's account portal. Once deleted, your phone number is disassociated from the profile and verification texts stop. There's no account on your end that gets affected — you're simply removing stored payment details from Stripe's system.
What Is a Link Verification Code in General?
Outside of Stripe Link specifically, a link verification code is a one-time password (OTP) sent via SMS to confirm your identity on a platform. When you try to log in, reset a password, or set up a new device, the system generates a short numeric code — usually 4 to 8 digits — sends it to your registered phone number, and gives you a narrow window (typically 3 to 10 minutes) to enter it.
The logic is straightforward: even if someone steals your password, they can't get in without also controlling your phone.
Where These Codes Appear
- Login confirmation — triggered when signing in from a new device or location
- Password reset — confirms you own the account before allowing a credential change
- New account or device setup — verifies the phone number belongs to the person registering
5 Common Reasons You Received an Unexpected Link Verification Code
1. Someone Entered Your Phone Number by Mistake
A typo during signup, checkout, or account recovery can redirect a verification text to the wrong person. One wrong digit is all it takes. This is almost always harmless — the code expires, nothing happens, and the texts stop on their own. If they keep coming from the same service, it's worth blocking the sender.
2. A Login Attempt Was Made on Your Account
If someone has your username and password — possibly from an old data breach — they may be trying to log in and the 2FA code is the last barrier stopping them. This one matters. The fact that the code came to your phone means they haven't gotten in yet, but it's a clear signal to change your password immediately.
What's often overlooked here is the data breach connection. As noted in the Wikipedia overview of credential stuffing, billions of username and password combinations from past breaches circulate widely and are used to run automated login attempts across popular services. This is why you might receive a code for a platform you haven't thought about in years.
3. A Password Reset Was Requested
Someone clicked "forgot password" on an account tied to your phone number. It doesn't mean your account has been accessed — yet. But if you didn't request it, someone is trying to change your credentials. Change your password now and don't wait.
4. Two-Factor Authentication Triggered from a New Device
If your account has two-factor authentication enabled and someone attempts to sign in from an unrecognised device or location, the code gets sent automatically. A single unexpected code might be a login attempt that failed. Repeated codes in a short window usually mean someone is actively trying to force their way in.
5. A Scammer Is Testing Account Access
Some verification texts are part of a broader social engineering attempt. The attacker triggers the code, then calls or messages you pretending to be customer support, your bank, or a delivery service — asking you to "read back the code for verification."
Never do this. Legitimate companies do not call you to ask for a verification code they just sent you. That pattern, every single time, is a scam.
Is a Link Verification Code Text a Scam?
Not automatically. The same message format is used for both legitimate security checks and fraudulent attempts. Context is the deciding factor.
When It Is Likely Legitimate
- It follows an action you just took (logging in, resetting a password, completing a checkout)
- The sender name matches a service you actually use
- The message contains no link, or only links to the company's own verified domain
- There's no follow-up call or message asking you to share the code
When It May Be a Scam
- It arrived with no action from you and was quickly followed by a call or text
- The link looks shortened, mismatched, or slightly misspelled (e.g., "str1pe.com" instead of "stripe.com")
- The language is urgent or threatening ("Your account will be suspended")
- The sender number looks like a random mobile number rather than a short code or named sender
How to Verify a Sender Without Clicking the Link
Don't click anything in the text. Instead, open your browser and manually type the company's official website address. Log in from there and check your account activity. Most platforms — Google, Apple, Meta, your bank — show recent login attempts and active sessions in their security settings.
You can also search the sender's short code number on your carrier's website or a spam-reporting database to see if others have flagged it.

Security Risks You Should Understand
SIM Swapping — What It Is and Why It Matters
SIM swapping is when an attacker contacts your mobile carrier and convinces them — usually through social engineering or stolen personal details — to transfer your phone number to a SIM card they control. Once that transfer happens, every SMS sent to your number, including verification codes, goes to the attacker instead of you.
As reported by TechCrunch, SIM swap attacks exploit a weakness in mobile carrier security controls that allows support representatives to make account changes without always requiring the customer's direct authorisation — and major US carriers have only recently begun rolling out optional protections that aren't enabled by default.
This is why security professionals consider SMS-based two-factor authentication the weakest available form of 2FA. It's better than nothing. But it has a known exploit that doesn't require touching your device at all.
Smishing (SMS Phishing)
Smishing is phishing carried out via text message. The attacker impersonates a trusted company, creates a sense of urgency, and either asks you to click a link or share a code.
Unlike SIM swapping, smishing relies entirely on you taking an action — which means it's also entirely preventable by simply not engaging.
In practice, security teams commonly report that smishing attempts are harder for users to detect than email phishing, partly because people are less conditioned to be suspicious of text messages and partly because mobile screens often hide full URLs, making spoofed links harder to spot.
Malware via SMS Links
Clicking a malicious link in a fake verification text can install software on your device that runs in the background. Depending on what gets installed, it may log your keystrokes, capture future verification codes as they arrive, or redirect your browser to attacker-controlled pages when you try to access banking or email. In shared device environments or business settings, this can extend well beyond one compromised account.
What to Do the Moment You Receive an Unexpected Verification Code
Step 1 — Do Not Share the Code with Anyone
Full stop. The code expires within minutes. Its only value is to whoever triggered the login attempt. No legitimate company will ever contact you to ask for a code they just sent you. If someone is calling and asking — hang up.
Step 2 — Identify Which Service Sent It
The text usually names the platform. Go directly to that service by typing its URL into your browser. Do not tap the link in the text, even if it looks real. Navigate to your account security settings and review recent activity.
Step 3 — Check Your Login History
Most major platforms — Google, Apple, Facebook, your bank — show active sessions and recent login attempts in account settings. If you see a session you don't recognise, end it immediately from the security page.
Step 4 — Change Your Password
If someone triggered a code on your account, assume they have your current password. Change it immediately. If you've reused that password anywhere else, change it on those accounts too. A password manager makes this significantly less painful.
Step 5 — Switch from SMS 2FA to an Authenticator App
Apps like Google Authenticator or Authy generate time-based codes directly on your device. They are not tied to your phone number, which means SIM swapping can't intercept them.
Most major platforms allow you to switch to an authenticator app under security settings. It takes about five minutes and meaningfully reduces your exposure.

Conclusion
A link verification code text is either a routine security check or a signal that someone is trying to access your account. Don't share the code, check your account activity, update your password if anything looks off, and consider switching from SMS to an authenticator app for stronger protection going forward.
Frequently Asked Questions
Does receiving a verification code mean my account has been hacked?
Not necessarily. The code arriving on your phone means the attacker hasn't gotten in yet — your 2FA is doing its job. It does suggest someone may have your password, so changing it immediately is the right move.
Is it safe to click the link inside a verification code text?
Only if you triggered the action yourself and the sender is confirmed legitimate. When in doubt, go directly to the platform by typing the URL manually instead of tapping any link in the message.
What is Stripe Link and why is it sending me verification texts?
Stripe Link saves your payment details for faster checkout on Stripe-powered stores. If your phone number is associated with a Link profile — even accidentally — you'll receive verification texts at checkout. You can delete your data through Link's account portal to stop them.
What is SIM swapping and how does it affect my verification codes?
SIM swapping is when an attacker transfers your phone number to their own SIM by deceiving your mobile carrier. After that, all SMS codes go to them, not you. Switching to an authenticator app removes this risk entirely.
What should I do if I keep getting verification codes I never requested?
Change the password on the relevant account, review your login history, and enable or upgrade your 2FA method. If codes keep arriving from the same service, contact that company directly through its official support channel.
