Coming to Boston

Every lost thing has a story. Help it get home.

Found a book on the Red Line, a mitten on the Common, an AirPod at Park Street? Snap it, drop a pin, and Last Seen turns it into a cheerful FOUND! poster that Boston can share until it's back where it belongs.

How it works

  1. 1

    Snap it

    Found something? Take a quick photo and drop a pin where you found it. Takes seconds.

  2. 2

    Post it

    Last Seen makes a bright, shareable FOUND! poster so friends, classmates and neighbours can spread the word.

  3. 3

    Get it home

    Owners search their area, prove it's theirs, and arrange a safe hand-off. Happy reunion unlocked.

Safe by design

Exact spot hidden

Posters show the general area, never the precise pin, so only the real owner knows where they lost it.

Owner-only questions

Finders set a question only the owner could answer, like what's written inside the cover, before anything changes hands.

Safe public hand-off

Meet somewhere busy and public, like a station entrance or café, or leave it with a staffed lost-property desk.

Found something valuable? Wallets, phones, IDs and cash should go to the police or the venue's lost-property office (in Massachusetts, the law expects finders to report valuable items). Last Seen helps spread the word and can point owners to where you handed it in.
