Free short links for small businesses, lsu.kr
lsu.kr turns long promotional addresses for your shop or group into short links that fit neatly into KakaoTalk, SMS and Band, for free. Recipients can add + to the end of a link to preview the destination and safety status before going there.

Safety checks
- Only domains registered at least 1 month (30 days) ago (blocks freshly registered phishing and illegal domains)

- Matches against malware and phishing threat lists (URLhaus, OpenPhish)
- Analyzes page content to block gambling, adult, drug, piracy and illegal-finance sites
- Every redirect is checked the same way; internal network addresses are blocked
- Links are re-checked every 3 hours and screened against hacking/phishing lists on every visit, and blocked immediately if they turn illegal or harmful
- Links with no visits (clicks) for 3 months (90 days) are deleted automatically, and a deleted address cannot be taken by anyone else for 1 year.
All links and clicks are logged and may be provided to authorities on lawful request.
Found an illegal or harmful link, or have a question?
How does lsu.kr work?
Enter an original address (a homepage, booking form, map and so on) and it becomes either a subdomain link with a name of your choice (shopname.lsu.kr) or an automatically generated short link. You can create one instantly without signing up, and a management password is issued right after creation.
See the KakaoTalk, SMS and flyer guides for step-by-step examples for each situation.
How do recipients confirm it is safe?
Every link goes through checks at creation — domain registration age, whether it is reachable, comparison against the KCSC block list and malware/phishing lists (URLhaus, OpenPhish) — and is re-checked every 3 hours. Adding + to the end of a link shows the destination address and this check status before you actually go there.
See how to check if a short link is safe for the full method.
Are there stats and management tools too?
You can check stats like click count, visitors, country/device and referral source. Guests manage links with a management password, and members manage them from My Page, including changing the destination and pausing or resuming.
Frequently asked questions
Is lsu.kr free?
Yes. You can create a short link for free without signing up.
Can I choose the name in the link?
Yes. You can set the subdomain name yourself, like shopname.lsu.kr, using 4 to 32 lowercase letters, digits and hyphens. The short path code after the domain, however, is always generated automatically as 6 characters.
Can bots or spam programs create links too?
No. Only links created by a person using a real browser are allowed, so automation programs cannot create them.
Is there an ad when the link redirects?
Human visitors may see a Coupang Partners banner for about 2 seconds before redirecting. Search engines and preview bots redirect immediately. See about lsu.kr for details.
