If someone sends “LTK” in a text or you see it on TikTok or Instagram, it usually means “Let Them Know.” However, LTK can also refer to the popular LTK (formerly LIKEtoKNOW.it) shopping platform used by influencers. The correct meaning depends entirely on the conversation and platform.

Quick Answer
LTK is most commonly:
- Let Them Know (text abbreviation)
- LTK (formerly LIKEtoKNOW.it), a fashion and shopping platform
- Less commonly, it can represent technical or company-specific abbreviations in professional contexts.
What Does LTK Mean in Text Messages?
In texting, LTK stands for “Let Them Know.”
It’s a shorthand people use when asking someone to pass along information or notify another person. Instead of typing the entire phrase, they simply write LTK.
Examples include:
- LTK when you get home.
- LTK if she’s still coming.
- LTK what they decide.
The abbreviation keeps conversations short while still sounding natural.
Unlike internet slang such as LOL or IDK, LTK isn’t used by everyone. It’s relatively uncommon, so some people may not recognize it immediately.
All Real Meanings of LTK
Depending on where you see it, LTK has several legitimate meanings.
1. Let Them Know (Most Common in Texting)
Type: Text abbreviation
Meaning:
Tell someone else the information.
Example:
I’ll be late. LTK I’ll arrive around 8.
Here, the sender is asking someone to pass the message along.
2. LTK (Formerly LIKEtoKNOW.it)
Type: Brand name
On Instagram, TikTok, Pinterest, fashion blogs, and creator profiles, LTK usually refers to the influencer shopping platform.
Creators often write:
- Shop my LTK
- Link in my LTK
- New outfits on LTK
In this context, it has nothing to do with texting.
Instead, it’s a shopping marketplace where influencers share products and earn commissions.
3. Technical or Industry Meanings
Outside social media, LTK occasionally appears as an abbreviation inside businesses or specialized industries.
Examples include internal company names, software abbreviations, engineering terminology, or organization initials.
Unless you’re reading professional documents, these meanings are usually irrelevant.
A Common Misunderstanding
Many people assume LTK always means “Let Them Know.”
That’s true in text conversations.
However, on Instagram or TikTok, seeing someone write:
“Everything is linked in my LTK.”
does not mean “Let Them Know.”
It refers to the shopping platform.
The easiest way to understand LTK is to ask:
Is this a conversation or a creator recommending products?
That single question usually tells you which meaning is correct.
Which Apps Is LTK Used On?
Text Messages
Very common for “Let Them Know.”
Example:
LTK when you’re outside.
Occasionally used in quick chats among friends or family.
Example:
LTK if Mom already left.
Snapchat
Appears occasionally in private conversations.
Not considered Snapchat-exclusive slang.
Most often refers to the influencer shopping platform.
Examples include:
- Shop my LTK
- New finds on LTK
- LTK link in bio
TikTok
Creators regularly mention LTK when sharing fashion, beauty, home décor, and lifestyle recommendations.
In comments, however, some users still use LTK = Let Them Know.
X (formerly Twitter)
Both meanings appear, but context matters.
Shopping creators usually mean the platform.
Casual users may mean “Let Them Know.”
Grammar: How Is LTK Used?
LTK is a text abbreviation rather than a standard part of speech.
Most often it functions like a shortened command.
Examples:
- LTK when they arrive.
- LTK if plans change.
- LTK whether she’s coming.
It can appear:
- At the beginning of a sentence
- At the end
- In the middle of a message
Unlike “OK” or “LOL,” LTK usually cannot stand alone as a complete reply.
For example:
Friend:
Should I tell everyone?
Reply:
LTK.
While understandable, most people would instead say:
Yeah, LTK.
or
Please LTK.
Where Did LTK Come From?
Let Them Know
The texting abbreviation likely developed naturally as mobile messaging became more common.
Unlike slang with a clearly documented first appearance, there isn’t reliable evidence identifying exactly who first shortened “Let Them Know” to LTK.
Its origin is therefore considered unclear.
LTK Shopping Platform
The shopping platform began in 2011 under the name LIKEtoKNOW.it.
As the company expanded globally, it officially rebranded to simply LTK in 2021 because the shorter name was easier to remember across social media.
The two meanings developed independently.
Is LTK Part of AAVE?
No reliable evidence connects LTK (“Let Them Know”) to African American Vernacular English (AAVE).
Instead, it appears to be a straightforward abbreviation created through everyday internet and texting habits.

Why Has LTK Stayed Popular?
Unlike many internet abbreviations that disappear after a few years, LTK has remained relevant because its most common meaning evolved beyond texting.
Originally, some people used LTK as a friendly sign-off in messages. Over time, the launch and growth of the LTK influencer-shopping platform gave the abbreviation an entirely new life. Millions of creators now use it daily, making the platform meaning far more recognizable than the original texting abbreviation.
This shift shows how internet abbreviations can change meaning as digital culture evolves. Today, many users first encounter LTK while shopping through creators rather than chatting with friends.
