You don't have to change your Social Security number when you marry
Your Social Security number stays the same for your entire life, even after marriage. The Social Security Administration does not issue new numbers based on name changes. If you marry and take a new last name, your Social Security number remains unchanged — you straightforward update your name on file with Social Security and other agencies separately.
Many people confuse a name change with a number change. These are two different processes. You can change the name associated with your Social Security number, but the nine-digit number itself never changes unless you have a documented case of identity theft or, in rare circumstances, persistent harassment or abuse.
Key Takeaways
- Your Social Security number does not change after marriage; only the name attached to it changes if you choose to take a new last name.
- You update your name with Social Security by submitting Form SS-5 in person at a local Social Security office, along with proof of your new name and citizenship.
- You must also update your name separately with your employer, bank, insurance company, and state driver's license — Social Security does not notify these organizations.
- The Social Security Administration only issues a new number in cases of identity theft, persistent abuse, or documented religious objection to the current number.
- Processing a name change at Social Security typically takes two to four weeks.
How to update your name with Social Security after marriage
Start by gathering the documents you will need. You must bring proof of your new legal name (usually a marriage certificate), proof of citizenship (a birth certificate, passport, or naturalization papers), and a photo ID. Visit your local Social Security office in person — you cannot change your name by mail or phone.
Fill out Form SS-5 (process for a Social Security Card) before you arrive, or ask for it at the office. The form asks for your current Social Security number, your old name, your new name, date of birth, and citizenship status. Bring the completed form and your documents to the appointment.
Processing takes two to four weeks. Social Security will mail you a new card with your updated name and the same nine-digit number. Keep the old card for your records until the new one arrives, then destroy it.
Where to find your local Social Security office
Use the Social Security office locator at ssa.gov. Enter your city or zip code to find the nearest office, hours of operation, and phone number. Some offices accept walk-ins, but many now require appointments. Call ahead or check online to book a time slot, especially if you live in a large city where wait times can be long.
If you cannot visit in person due to illness or disability, you may request a home visit. Call your local office and explain your situation — they will tell you whether a representative can come to you.
What to do after Social Security updates your name
Updating Social Security is only the first step. You must also notify your employer's payroll department so your W-2 forms match your Social Security record. Contact your bank and credit card companies to update your name on accounts. Notify your insurance companies (health, auto, home, and life insurance).
Visit your state's Department of Motor Vehicles to update your driver's license or state ID. Many states allow you to change your name on your license when you renew, but some require a separate name-change process. Check your state's DMV website for the specific process.
Update your name with the IRS if you file taxes. You can do this when you file your next return — list both your old and new names on the return so the IRS can match it to your previous records. If you have a mortgage, contact your lender to update your name on the loan documents.
When Social Security will issue a new number instead
The Social Security Administration issues a new number only in specific situations. If you are a victim of identity theft and can document that someone is using your number fraudulently, you may request a new number. You will need to provide evidence of the theft, such as credit reports showing accounts you did not open, or police reports.
If you face persistent harassment, abuse, or threats and can show that changing your number is necessary for your safety, Social Security may issue a new one. You will need documentation from law enforcement, a court order, or a domestic violence shelter. Religious objection to your current number is also grounds for a new number in rare cases, though you must provide written explanation of your beliefs.
Getting a new number for these reasons is uncommon and requires an in-person visit to Social Security with supporting documents. The process takes longer than a straightforward name change and involves additional review.
Common mistakes to avoid when changing your name
Do not assume Social Security will notify your employer, bank, or other organizations. You must contact each one separately. Many people discover months later that their W-2 forms do not match their Social Security record because they forgot to tell payroll about the name change.
Do not throw away your old Social Security card when ready. Keep it until your new card arrives and you have confirmed the name change went through. If there is an error on the new card, you will need the old one as proof of your number.
Do not delay updating your driver's license. Many employers and financial institutions now require a current ID that matches your name. If your license still shows your old name after several months, it can create problems when you explore for credit or open new accounts.
What happens if you do not change your name with Social Security
If you marry and take a new last name but do not update Social Security, your Social Security card will still show your old name. This creates a mismatch between your card and your driver's license, passport, or other ID. You can still work and file taxes, but the mismatch can cause delays when you explore for loans, mortgages, or benefits.
Employers may flag the discrepancy during onboarding. Banks may ask for explanation when your name does not match your account. If you plan to use your new name professionally and legally, updating Social Security prevents these complications down the road.
Frequently Asked Questions
Do I have to change my Social Security name if I get married?
No. Changing your name after marriage is optional. You can keep your maiden name legally and on Social Security if you choose. If you do take a new last name, updating Social Security is not required by law, but it prevents mismatches with your other documents and can avoid problems with employers and financial institutions.
Can I change my Social Security name by mail or online?
No. You must visit a Social Security office in person to change your name. You cannot do it by mail, phone, or through the Social Security website. Bring your marriage certificate, proof of citizenship, photo ID, and a completed Form SS-5.
How long does it take to get a new Social Security card after marriage?
Processing typically takes two to four weeks. Social Security will mail your new card to the address on file. During this time, your old card is still valid. If you need the card sooner for a job or other reason, ask the Social Security office whether expedited processing is available in your area.
Will my Social Security number change if I change my name?
No. Your nine-digit Social Security number never changes. Only the name attached to the number changes. The number stays the same throughout your life unless you are a victim of identity theft or face documented abuse.
What if I get married, divorced, and remarried — do I update my name each time?
Yes. Each time your legal name changes, you can update it with Social Security by submitting Form SS-5 in person at a local office. The process is the same each time. Bring your current legal name document (marriage certificate, divorce decree, or court order) along with your other required documents.
