Understanding the Social Security Number

Your Social Security number is an essential 8-digit code assigned to every citizen, used to identify you in all interactions with Social Security throughout your life. Here are some key facts:

  • Assigned at birth: Parents must register their child as a beneficiary on the mother’s or father’s health card. The baby then receives a health card with a unique Social Security number.
  • Employment affiliation: When you start working and sign an employment contract, this number becomes your official Social Security affiliation number.

Methods to Find Your Social Security Number

1. Check Your Health Card

The quickest way to find your Social Security number is on your health card. On the back, look for a number with several digits preceded by "SS" (for Social Security).

  • The first two digits represent your province code.
  • They are followed by the 8-digit Social Security number in italics.
  • The final digits are control numbers.

2. Look at Your Medical Prescriptions

Your Social Security number is often printed on medical prescriptions. Alternatively, you can visit your local health center and request your number with a valid ID.

3. Check Your Pay Slips or Social Security Documents

If you are employed, your pay slip will display your Social Security number in the upper section. Official documents from Social Security, such as benefit notifications, will also contain your number.

4. Call Social Security

If you cannot find any documents, call Social Security at 901 50 20 50. Provide your name, surname, and ID to retrieve your number.

5. Use the Social Security Electronic Office

If your mobile number is registered with the General Treasury of Social Security, you can retrieve your number online. Use the Duplicate Affiliation Document Service to receive your number via SMS.

Additionally, you can access your Social Security number using:

  • Digital Certificate
  • Username and Password
  • Cl@ve System
