Use case

A lost and found board people actually check

Lost keys, a found wallet, an ID card on a bench — post it once with the details that get it home.

Get started free

When something goes missing, a message in one group chat reaches thirty people and is buried by evening. A shared lost and found board works better because everyone looking — owners and finders — checks the same place. Asyncbit's lost and found board takes a post marked lost or found, with a title, description, location, photos and a category: electronics, stationery, clothing, ID card, keys, wallet, bag, bottle or other.

Unresolved items also appear in the For you feed, so a post reaches people who never open the board. Contact happens through chat rather than phone numbers, and when the item is back with its owner you mark the post resolved. Two things to know: 1:1 chats need a mutual follow, so owner and finder follow each other before messaging; and lost and found posts carry your name.

The problem

Posts vanish in a day

A “has anyone seen my blue bottle?” message scrolls away before the person who picked it up ever sees it.

Finders don't know where to post

Someone found your keys and wants to return them, but there's no obvious place to say so.

Anyone can claim anything

Post “found a wallet” and three people say it's theirs. The finder needs a fair way to check.

Notices stay up forever

Nobody updates the post after the item is found, so people keep searching for something that's already home.

How to do it on Asyncbit

  1. 1

    Post it quickly, with a category

    Pick lost or found, choose the category, and write a plain title: “Lost: black backpack with laptop, main library”. The sooner you post, the more likely someone still remembers seeing it.

  2. 2

    Add the location and the right details

    Say where and roughly when. Add a photo if you have one. If you lost it, describe it — but keep back one detail (a sticker, what's inside) that only the owner would know.

  3. 3

    Check the other side of the board

    Lost something? Look through found posts in the same category. Found something? Look for a matching lost post before posting your own.

  4. 4

    Talk in chat, not over the phone

    Arrange the return through chat. Because 1:1 chats need a mutual follow, follow the other person and ask them to follow back. You don't have to share a phone number with a stranger.

  5. 5

    Hand it over and mark it resolved

    Meet somewhere public, or hand the item to a staffed desk. Then mark the post resolved so it stops showing up as an open item in people's feeds. Resolving also earns you points (10 by default).

If you found something

  1. 1

    Photograph it without the sensitive parts

    Show a wallet or bag from the outside. For an ID card, post the category and location but don't show the card number, photo or address.

  2. 2

    Ask the claimant to describe it

    Ask what's inside, a distinguishing mark, or exactly where they lost it. The real owner answers without guessing.

  3. 3

    Hand it over safely

    Meet somewhere public, or leave it with a front desk or security office and tell the owner where it is.

When the board isn't enough

Because lost and found posts are named, keep your own details light: say the area, not your address. Our guide on protecting your privacy on social media covers the habits that matter most. A board like this works best as part of a wider online community where people already check in daily.

Nobody claimed an item after a long wait, or you're clearing out things you no longer need? That's a different job: hand unclaimed items to the place they were found, and use the marketplace for your own things — see how to buy and sell locally.

The features you'll use

Frequently asked questions

What categories does the lost and found board use?
Electronics, stationery, clothing, ID card, keys, wallet, bag, bottle and other. Each post is marked as either lost or found.
Who sees my lost or found post?
Everyone who browses the lost and found board. While the item is unresolved, the post can also appear in members' For you feeds.
Do I have to share my phone number?
No. People contact you through chat. A 1:1 chat needs a mutual follow, so you follow each other first.
What happens when I mark a post resolved?
The item is shown as resolved, it stops appearing among unresolved items in the For you feed, and you earn points (10 by default).
Can I post a lost item anonymously?
No. Lost and found posts are posted under your name, which also helps the other person trust the exchange.
