I started working at that age too, but certainly didn't need an ID to get a job (and never have at any point in my life, afaicr - and I've never even heard of 'working papers'). Are you talking about in the states? Cause for jobs (at least those that aren't under the table) I've only ever needed a social security number.

Everyone who works in the united states must fill out form I-9 to prove your eligibility for employment.

Report card/school records is an option for children who don't have an ID. So ID doesn't appear to be strictly needed until one turns 18.

Working papers are permission to work as a minor - https://dol.ny.gov/working-papers this site says you get them from your school now. Back in the day when I got mine you had to go to the DMV.

Huh, I don't remember needing to get working papers, but I vaguely recall needing a parent signature - I was also pretty rural tho, so you kinda know most people around anyway. Presumably, social security card/birth certificate would be enough as well.
