How to identify if there is a problem with the Social Security Number (SSN)?

There are three cases:

-If the worker has two or more Social Security Numbers.

-If the employer reports a different Social Security Number than the one the worker has contributed to.

-If the worker shares the Social Security Number with another worker.

If it is detected that there are any of these errors, you must go to the IMSS to certify the NSS and subsequently to the AFORE to begin the correction.
