What to do if your employer gets a Social Security no match letter

This page covers Social Security no match letters only. It is general information, not legal advice. If your employer is doing a full check of everyone's work papers, or immigration agents sent a notice of inspection, see My employer is auditing everyone's work papers.

We know a letter like this can make your stomach drop. Take a breath. A no match letter is a paperwork notice, not an immigration case. You have time to get good advice before you do anything.

What is a no match letter?

Every year, employers send Social Security a W-2 for each worker. Social Security tries to match each name and number to its records so your pay counts toward your future benefits. When a name and number do not match, Social Security can tell the employer. That notice is often called a "no match" letter. Its official name is an Employer Correction Request, or EDCOR.

Mismatches happen for many ordinary reasons:

• A typo in your name or number
• A name change after marriage or divorce that was never updated
• Two last names, or names written in a different order
• A hyphen, accent or space handled differently by different offices
• A mistake in the employer's own payroll records

Some mismatches happen because a worker used a number that is not theirs. The letter does not say which reason applies. It does not know.

What does the letter actually say?

Social Security's own sample letter is clear. It says the letter:

• Does not mean you or your employer meant to give wrong information
• Does not address your work authorization or immigration status
• Should not be used to lay you off, suspend you, fire you or treat you differently just because your name and number do not match

The letter asks the employer to correct the record. It tells them to use Social Security's free online system, Business Services Online, to see which names and numbers did not match, and to fix errors with a corrected W-2, called a W-2c.

Can my employer fire me because of the letter?

Not just because of the letter. Social Security tells employers in plain words not to take action against a worker only because of a mismatch. And in California, several laws protect you:

• Your employer cannot ask for more or different papers than federal law requires, or refuse papers that look real. That is an unfair immigration related practice. Penalties can reach $10,000 per violation.
• Your employer cannot threaten to report you to immigration, or report you, to punish you for using a right at work. That counts as retaliation under California law.
• If you lawfully changed your name, Social Security number or work permit, California law says your employer cannot fire you or punish you for updating, or trying to update, that information (Labor Code 1024.6).

Here is the hard truth, too. Federal law says an employer may not keep employing someone it actually knows is not allowed to work in the United States (8 U.S.C. 1324a(a)(2)). A no match letter alone does not give them that knowledge. But if you tell your boss you do not have papers, or hand over a document that shows it, that can change your situation. That is why you should get advice before you say or give anything about your status.

Talk to an immigration attorney and an employment attorney about your exact facts. Free help is listed below.

What should I do first?

1. Stay calm and keep working. Do not quit before you get advice.
2. Ask for a copy of what your employer received. Ask in writing if you can, by text or email. Note the date on it.
3. Write down what was said. Who talked to you, the date, the time, and their exact words. Do it the same day.
4. Do not sign anything you do not fully understand, like a statement, a resignation or a new form. You can say, "I want to take this home and get advice first."
5. Do not hand over a different Social Security number or new documents until you talk to an immigration attorney or a DOJ accredited representative.
6. Never give false papers. It can hurt you badly in any future immigration case. Ask an immigration lawyer before you do anything with documents.
7. Call a free workers' rights clinic. Legal Aid at Work has an East Palo Alto line. See Who can help?

What does Social Security tell my employer to do?

Social Security's instructions to employers are simple:

• Look up which names and numbers did not match in Business Services Online
• Check the Social Security Number Verification Service
• Work with the worker to sort out the mismatch
• Fix errors with a corrected W-2 (Form W-2c)
• Do not lay off, suspend, fire or treat a worker differently only because of the mismatch

Nothing in those steps tells your employer to give you a new I-9 form. In California, asking for more or different papers than the law requires is illegal.

Legal Aid at Work, a free legal nonprofit, has sample letters a worker can give an employer to explain what no match letters mean. The letters were written in 2020 and updated in 2024. Ask the clinic before you send one.

What if the mistake is real and easy to fix?

If you have a valid Social Security number and the problem is a typo or a name change:

• Compare the name and number on your Social Security card with your pay stub and W-2.
• If your employer made a typo, show them your card and ask them to correct it.
• If your name changed and Social Security still has your old name, update it with Social Security first. Then give your employer the corrected information.

For the steps, see How to update your Social Security number with your employer.

What if I do not have a valid Social Security number?

This is the hardest situation, and it is where good advice matters most.

• You do not have to explain your status to your employer in that moment. You can say, "I need to get advice before I answer."
• Talk to an immigration attorney or a DOJ accredited representative first. They can tell you whether you may qualify for something that gives you a real number, and what risks you face. See Free legal help in the Bay Area and How to find a trusted lawyer.
• Your wages are still yours. If you worked, you must be paid for all of it, whatever your status. See How to file a wage claim and What to do if your paycheck is late or bounces.
• Make your family plan now. If you are worried about immigration, a plan helps your children and your home. See Make a family preparedness plan.

What if I was already fired?

You still have rights.

• Get your final paycheck. If you were fired, your employer must pay all wages you earned right away, including unused vacation. If they pay late, they may owe a penalty of one day's pay for each day late, up to 30 days. See Your final paycheck.
• File a retaliation complaint if you were fired, suspended or threatened after you complained about pay or safety, or used another right at work, or if your employer threatened to report you to immigration. You usually have 1 year. The Labor Commissioner does not ask about your immigration status, and you do not need a Social Security number or photo ID to file.
• File a federal charge if your employer demanded more or different papers than the law requires, or treated you differently because of your citizenship status. You have 180 days.
• Talk to a clinic before you sign a severance or release. See Should I sign a severance agreement?

For what counts as retaliation, see What counts as illegal retaliation at work.

Does the letter mean immigration is coming?

No. A no match notice is about Social Security records and wages. It is not an immigration order, a court notice or a warrant. It does not say anything about your status.

California employers must give workers a yearly notice of their rights, including rights about unfair immigration related practices. Ask your employer for it.

If you ever do get a notice from immigration, or agents come to your job, see If immigration agents come.

Questions people ask

Will Social Security tell immigration about me? The no match letter itself says it does not address immigration status. It does not say whether Social Security shares this information with other agencies. Before you contact Social Security or change any records, ask an immigration attorney about your own risk. Find free legal help.

My boss says I have 10 days to fix it or I am out. Is that legal? Social Security's letter sets no deadline for you. An employer that fires you only because of the mismatch may be breaking the law. Call a clinic before the deadline and keep records of what was said.

Can my employer make me fill out a new I-9? Not just because of a no match letter. Asking for more or different papers than the law requires is illegal. If your work permit is expiring, that is different. See What papers your employer can ask for, and when they can recheck them.

Should I quit before they fire me? Not before you get advice. A clinic can tell you what quitting would mean for your pay and your claims.

Can I still get paid for the hours I already worked? Yes. California's labor laws protect all workers, whatever their immigration status.
