The rule that keeps you safe

Give it after you are hired, on paper or on the employer's own onboarding form, and never through platform messaging. Anyone asking earlier is either careless with your identity or trying to steal it, and neither one is worth the job.

Nothing about applying needs it. Not being considered, not being offered work, not proving who you are. The number exists so the government can match income to a person, which only matters once you are working.

When an employer really does need it

There are three normal reasons, and all three happen after you are hired.

• An I-9, which every employee fills out to show they can work in the US.
• A W-4 and a W-2, if you are being hired as an employee with taxes taken out.
• A W-9, if you are being paid as a contractor and they will send you a 1099.

How to hand it over safely

On their form, in person or through their own onboarding site. Paper handed to a person is fine. A secure company portal is fine.

Never in a chat message here. Never in a text or an email. Never as a photo of your card, because that photo then lives in the other person's phone, in their cloud backup, and anywhere it gets forwarded.

If someone says the platform requires it, they are lying. We never ask for your Social Security number in messaging, and we never will.

The asks that are always a scam

Some requests are not carelessness, they are the whole point of the fake job.

• Your number before you have been hired, to run a check on you.
• A photo of your Social Security card or your driver license, sent in a chat.
• Your bank login, or your card number, for any reason at all.
• A fee you have to pay first, with your number attached to the form.
• Anyone rushing you, saying the spot goes away in an hour.

If you have already given it out

Do not panic, and do not wait either. The steps below are free and you can do all of them today.

• Put a fraud alert on your credit, which you only have to do at one of the three bureaus because they tell the other two.
• Freeze your credit at all three. It is free, it stops new accounts being opened, and you can unfreeze it when you need to.
• Pull your credit reports at annualcreditreport.com, which is the real free one, and look for accounts you did not open.
• Report it at identitytheft.gov, which walks you through a plan and gives you a report you can show a bank.
• Ask the IRS for an Identity Protection PIN so nobody can file a tax return in your name.

Signs somebody is using your number

Watch for mail about an account you never opened, a tax notice about wages you never earned, or a call from a collector about a debt that is not yours.

Any one of those is enough to act on. Start with the freeze, then the report, then deal with the specific account.

If you do not have a Social Security number

Some people file taxes with an ITIN instead, which is a number the IRS issues for tax purposes only. If that is you, the same rule applies. It goes on a tax form after you are hired, never in a message.

Be extra careful about anyone who says they can get you paperwork for a fee. Charging desperate people for documents is one of the oldest scams there is.
