There are 9 ways to find out your lost or forgotten SSS ID number. It is by online, from your employer, over the phone, at the SSS branch office, and on the SSS Forms.
1. Check your SSS ID number Online on the Website
The official website of SSS is www.sss.gov.ph. To check your SSS ID number online, visit the SSS website and log in to your User Account. You will find your SSS ID number in the upper-left corner of the webpage underneath your name. This is the fastest and easiest way to determine your SSS Number.

To view your SSS Number using the Mobile App, open the Mobile App on your Smartphone then log in to your User Account. You will view your SSS Number at the top center of your mobile phone’s screen.

3. Register in My.SSS using your CRN
This is another suggestion that you can do without leaving your home. If you have a Unified Multi-Purpose ID or UMID with a CRN. I suggest that you register in sss online at the website or using the mobile app. The agency knows your number, but one way for you to view it is to register for an online account.

Go to sss.gov.ph and visit the “member” link under the portal. You will be redirected to new screen. Proceed to “Not Yet Registered in My.SSS?”
On the sss website, you can register an online account using different options. But since you do not know your social security number, then select the “UMID.” Select the option to use your CRN. Fill up all the necessary fields. After you are successful with your registration, you can log in to your account. Immediately, you can view your sss number at the upper left of the page just below your complete name.
This option is only possible assuming you are not registered online yet. If you already have an online account and you do not know your login details, I suggest you proceed with password recovery.
4. Inquire about your SSS ID number from your Employers
Employers refer to the persons and companies that employ you.
To know your SSS ID number through your Employers, inquire about your SSS Number to the Human Resources Department of your current and previous employers and they will give you your SSS ID number.
Usually, our previous employer kept our personal information even after we separated from our job. They will also keep our government membership numbers for a certain number of years. Just maintain a good relationship with the human resource department so it will be a lot easier.
5. Retrieve your SSS Number by calling the Landline of the Social Security System
