Serial Number

The Mongoose website is pretty vauge about this issue. I have a Mongoose model marked with "Police" sticker.
It is second hand. I'm trying to locate the Serial Number on it, so I can register it. Can anyone tell me explicitly where
this would be engraved? I've looked everywhere I can think of. Thank you.

If you cant locate the factory s/n, I would think you can always add one of your own........
Check with your local PD

The three most common places are under the bottom bracket, on either rear dropout, and at the top of the seat tube, below the top tube joint. If you've checked all four places to no avail, you might contact Mongoose directly for more ideas.

A serial number engraved under the bottom bracket is often hidden or partially hidden under the cable guide. This is often the case with road frames using under the bb shell shift cable routing but not usually a problem with MTB frames that route all of the cables along the top tube.

Thank you to everyone who responded! The serial number is almost entirely filled in with heavy paint, it's stamped in under the crank.
The bike has a prominent decal reading "Police" on either side, on the top bar. (black electricians tape over the word in this pic). Previous owner had this partially covered with tape. Not sure if this will
discourage thieves or attract unwelcome police attention.

So this was probably a police bike. If so and bought used, it probably saw lots of use (or almost none), so expect some wear on parts where you don't usually see it such as the bottom bracket.

I see a rusty chain and cassette, so either care was limited or it was stored badly. Consider going to a bike co-op to have the hubs, pedals, bottom bracket and headset serviced, to forestall more unnecessary wear and tear.
