Got a link from an unknown number? Use this 2-minute verification flow (by message type), plus examples, safe reply templates, and what to do if you already clicked or shared information.

Key Takeaways

  • Do not click unknown links to verify anything.
  • Verify inside official apps and sites you open yourself.
  • Treat one-time codes like passwords.
  • If you clicked, you can still reduce risk quickly.

If you cannot verify the sender quickly, do not test the link. Verify the claim inside the official app or website you open yourself. If you cannot match it to a real account or delivery you expect, ignore it.

Why unknown-link texts are risky even when they look harmless

A link is an action, not information. The message is trying to move you from reading to doing, often before you know what you are dealing with.

Once you click, you are no longer evaluating the sender. You are interacting with a page that can ask for logins, payments, or personal details while you are still in a rushed mindset.

Unknown-link scams are conversion funnels: get the click first, then decide what to steal (login, money, or identity data).

Text-link scams scale because they do not need to target you personally. They only need you to click once. Today the landing pages can be AI-written, localized, and brand-consistent, so treat polish as noise and rely on controlled verification plus link warnings.

What makes an unknown link risky (and what doesn’t)

Destination: shortened links and odd domains are risky because they hide where you land.

Urgency: urgency is used to prevent verification. Real issues can be verified through official apps.

Codes and logins: the damage is usually credential entry, not the click itself.

Payments: any link that asks for money or fees should be treated as high risk.

Identity: verify the claim through a channel you already trust (official app, saved contact, number on the card).

What an unknown link is trying to set up

Delivery, bill, or account problem: open the official app or website directly and check status there.

Money request: verify identity through a known number before doing anything.

One-time code: do not reply. Secure the account immediately.

Link with no context: treat as unverified. If it matters, they can explain without a link.

Common scripts you will see (and how to handle them)

A delivery link says your package is held

Delivery scams are common because they look routine and create urgency.

Instead, open the carrier app or retailer account and check tracking there.

A bank alert link says unusual activity

Some bank alerts are real, but links can also be traps.

Instead, open your bank app or call the number on your card (not the number in the text).

A message asks for a one-time code

Codes are often the last step needed to sign in as you.

Instead, do not share it. Change your password and enable two-step verification.

If you already clicked or replied, what matters now

If you clicked: close the page and do not enter information. Then verify through an official app you open yourself.

If you entered a password: change it now and enable two-step verification.

If you entered payment info: contact your card issuer and monitor charges.

If you replied: stop replying; block/report if the message continues.

When it is worth reporting, and who to report to

Report spam texts: use your messaging app report feature. Many carriers also accept reports via 7726 (SPAM).

It is safer to not click. Some links can lead to lookalike sign-in pages or push downloads. Verify through official apps or sites you open yourself.

What if the text says it is from my bank?

Do not use the link. Open your bank app directly and check for alerts or messages there.

Why do scammers ask for one-time codes?

Codes can let them sign in as you. Treat codes like passwords and never share them.

What should I do if I already clicked?

Close the page. Change any password you entered, enable two-step verification, and review account activity.

Should I reply and ask who it is?

Often the safest move is to not reply. If you do reply, keep it neutral and do not share personal info.
