I did this in Lipa City SSS branch at Sabang but I think most of the things would be about the same in all SSS branches.
Personal Data Recored or E1 Form
1. Download the Personal Data Record or E1 form
Before I went to the SSS branch I downloaded the Personal Data Record or E1 form from SSS website (https://www.sss.gov.ph/sss/appmanager/sss_downloads.jsp?type=forms). You have to print two copies of this because they’ll keep one and they’ll give you the other form. There are forms in the branches too which has a pink copy which will be given to you after you get your SSS number. The back portion of the form contains info on which items to fill up and how to fill up the forms. It also states the items needed when applying like PRC card or driver’s license, or birth certificate etc. You have to bring a photocopy of the ID that you’ll be using and the original ID when you apply. If you are a medical doctor and you are applying for the self employed status, you have to submit a photocopy of your PRC card as well.
Don't get lost.
2. Know where you should go.
First of all when I got to the building, I didn’t even know where the Entrance it. It was actually at the left side, the one where you see the stairs. At the foot of the stairs there is a security guard who will give you a number depending on what you will be applying for a loan, applying for ID, getting an SSS number etc. On the card with the number you will also find on what floor you should be going and what counter you should be submitting your requirements. They will call the number and you will give them the papers. You must make sure that you listen for your number in the right counter. This is because there are several counters taking care of different things and they are all calling out numbers. There are also a lot of people applying for IDs and thus the numbering there would almost be the same as that in the SSS number application counter.
3. Come really early.
I tried to come in after lunch hoping that there would be less people but I was sooo wrong. When I arrived they were calling out for number 100 and my number was 198 and still there were people coming until 3 pm. Most government offices in the Philippines are open from 8:00 am to 5:00 pm.
Wait for your number
4. Once your number is called...
Most of your time will be wasted waiting for your number to be called but once it’s called you will go to the counter and just check your personal info which is being typed by the person in the counter. She/he will write your SSS number on the paper. She will tell you what your contribution amount will be, when your contribution due date is and that you can pay it monthly or quarterly. The amount of your contribution depends on the amount of monthly earning that you declare on registration. The due dates of the contribution depends on the 10th digit of your SSS number. (Check it here: https://www.sss.gov.ph/sss/appmanager/pages.jsp?page=scheduleofcontribution). Once she gives you your copy of the E1 then you’re done.
About the SSS ID
5. You can't apply for the SSS ID immediately.
Since I wanted to have an SSS ID as soon as possible, I asked when I could apply for it. They said to come back after a week and verify at the counter if I’m already included in the system. I did not return though. I read somewhere that it was better to apply for ID once you have paid at least one contribution.
