Lookup Pass

A TEXT FROM A NUMBER YOU DON'T KNOW

Who sent that text? Look up the number before you reply.

A text can say it's from anyone: your bank, the post office, your kid on a new phone. The sender typed those words. The number is different. It has to run on a real phone network. That part is much harder to fake. Look it up first, then decide: reply, delete, or report.

The mistake almost everyone makes

There are three things people usually do with a strange text. Each one helps the sender.

You trust what the text says.

A text can claim to be your bank or your grandson. Anyone can type those words. Typing them costs nothing.

You search the number.

You get old directory pages covered in ads. Many are wrong, especially after a number moves to a new carrier.

You text back "Who is this?"

Now the sender knows a real person reads this number. You still don't know who they are.

WHAT THE SENDER DOESN'T WANT YOU TO SEE

There's a layer underneath every number

Every text has to pass through a phone company's network to reach you. Which company carries that number right now, what kind of line it is, and whether people have reported it: that is harder to fake than the words in a message.

Lookup Pass reads that layer. When a text says it's your bank but the number is an internet line people have reported for scams, you can see that before you tap the link. Not after.

A TEXT LIKE THIS

"Your package is on hold. Tap here to pay the redelivery fee." One look shows the number is an internet line with scam reports. You delete it and check the real tracking page yourself.

One look tells you who's really there

Every Lookup Pass includes all of this for any US phone number, right in your browser.

  • The company that carries the number's texts, and the one that carries its calls. Today's, not the one it started with.
  • The caller ID name on file for the number, when there is one.
  • The line type: mobile, landline, or an internet (VoIP) line.
  • Scam and spam reports from national reporting.
  • Your own number, re-checked every month. If a check finds a change, you get an email.
  • 50 lookups every month, plus 10 bonus lookups in month one.
  • Works in your browser, on your home screen, and in the Lookup Pass app.

How it works

Paste the number

Copy the number out of the text and paste it in.

See who's behind it

The messaging and voice provider, the caller ID name, and the line type.

See if it's been reported

Numbers reported for scams and spam are flagged, so you can decide whether to reply, delete, or report it.

INCLUDED WITH EVERY LOOKUP PASS

Your own number, watched

Lookup Pass keeps an eye on your number too. It's re-checked every month for the quiet changes you'd otherwise be the last to know about: a spam label showing up on your number, a port-out or SIM-swap move (the first step in many account takeovers), or your number quietly set up for texting through a provider you've never heard of.

When a check finds a change, you get an email that says exactly what changed and what to do about it. Not your friends, who quietly stopped answering your texts.

A TEXT LIKE THIS

"Hi Dad, I dropped my phone. This is my new number. Can you help me with something?" One look shows an internet line, not the mobile his son uses. That's enough to make him call his son's real number first. Nobody sends a cent.

Why you can't afford to reply blind

The people behind scam texts count on one thing: you can't tell who they really are.

Americans got 52.8 billion robocalls in 2024. The same phone that rings gets the texts too.
Americans reported losing $12.5 billion to fraud in 2024. The phone is still one of the main ways scammers reach people.
A text can put any name on your screen. The carrier behind the number is harder to fake.
Blocking one number does little. They switch numbers. Checking the number helps you decide what to do next.

IPHONE

Every doubt you're having right now, answered straight

"I'm not techy. I'll mess this up."

Paste the number. Get an answer. If you can copy a number out of a text, you can use this.

"Can't I just search the number?"

You can, and you'll often get an old directory page or a forum post nobody updated. It looks like an answer. It isn't a current one. Lookup Pass checks the number fresh, every time.

"What if it's nothing and I used up a lookup?"

Good. You go from "is this a scam?" to "nothing has been reported" in less time than it takes to make coffee. That's what you're paying for.

Does a clean result mean the text is safe?

No. A clean result means nothing has been reported against the number. That is not the same as safe. It is one more thing you know before you reply.

Does it tell me who the person is?

Not always. It shows the caller ID name on file when there is one, the carrier, the line type, and what's been reported. It tells you what a number is, never where a person is.

Does it read my texts?

No. You type or paste the number yourself. The Lookup Pass app never reads your contacts, call history, or messages.

How many lookups do I get?

50 every month, plus 10 bonus lookups in month one. They reset at the start of each billing month.

Does it work on my phone?

Yes. It works in any browser and you can add it to your home screen. The Lookup Pass app is on Google Play, and coming soon for iPhone.

Is $1.99 the whole price?

No. It's $1.99 today, the $18.00 balance at day 7, then $19.99 a month. The full breakdown is just below.

Let me be straight with you about the money

Lookup Pass is $19.99 a month. Month one is split into two payments: $1.99 today and the $18.00 balance at day 7. After that, it's $19.99 a month.

TODAY

$1.99

DAY 7

$18.00

the balance of month one

THEN

$19.99

a month after that

You get full access from the first day. Every lookup shows the carrier, the line type, the scam and spam reports, and the caller ID name when there is one.

One bad text can cost a lot more than $19.99. Money gone. Hours on the phone with your bank. Then a month of second-guessing every message.

The scam text your dad forwards you. The "your account is locked" message on your mom's phone. You check the number, tell them what's been reported, and nobody taps the link. That's what Lookup Pass is for.
