the most common questions people have about 3o2


What's 3o2.co?

It is an URL shortening service. By using 3o2.co you can create short URL address for easily sharing and reduce addresses complexity. E.g: an address like https://this-is-a-very-long/and-complex?address=you-may-wanna-share will be converted to https://3o2.co/[ABC].

Why 3o2.co?

Basically, 302 means the HTTP code for temporary redirects, so you can deliver the right message to your audience. Also, by using 3o2.co, you will get the advantage of all awesome features and first class support we provide.

How does it work?

Well, its logic is not complex at all.

Once you request an URL to be shortened, the 3o2.co algorithm will calculate a new (random) address for you and will store it together to the original address. Always someone uses your short URL link, we will increase our counters and record some other additional data, such as IP address and time. Then, you (or everyone else) can later check its statistics page. By creating a FREE account, you can have all your shorten links indexed in your account's dashboard to track their usage and performance. If you choose to go Premium, you will have access to additional features, such as custom domain (e.g: you.302.co); custom keywords (e.g: 3o2.co/try-it-now) and priority support.

Are short links and clicks statistics public?

Yes, they are.

How can I shorten an URL?

The simplest way to do it is by visiting our website and filling the form with the long URL. Also, you can use our API to integrate your own website/ app or our exclusive browser extension for Google Chrome.

Why there is a count-down before redirecting me to the long URL?

It is just because we want your audience to make sure they really want to go to the target URL. With the 5 seconds count-down, you will give the chance to your audience to give up before being redirected. Also, by giving them the change to decide before being redirected, or even report evil links, you will increase the trust between your audience and you.

Will a link report be sent to the link owner?

No. When someone reports a link, actually, it flags the link for review and there's no notification sent to the link owner if any. Our team will review the flagged links and decide upon keeping it live to remove it. However, if too many reports are given to a single link (boundaries are dynamic) our bots will put that link down automatically by removing it without prior notice.
