SSS Number vs. CRN vs. UMID: What’s the Difference?
The clear difference between your SSS Number, CRN, and UMID — plus practical guidance on which one to actually use when a form asks for either.
Sourced and cross-checked across multiple independent references, verified July 2026.
If you’ve ever gotten confused filling out a form that asks for your “SSS number or CRN,” you’re not alone — these three terms get used interchangeably online, but they’re genuinely different things. Here’s the clear breakdown, plus what actually matters: which one to use, and when.
Quick Reference
| SSS Number | CRN | UMID | |
|---|---|---|---|
| What it is | Your personal SSS membership number | A shared ID number across 4 government agencies | A physical ID card |
| Digits | 10 digits | 12 digits | N/A (card, not a number) |
| Format | ##-#######-# | ####-#######-# | Physical card |
| Used by | SSS only | SSS, GSIS, PhilHealth, Pag-IBIG | All 4 agencies (as ID) |
| Everyone has one? | Yes, if you’re an SSS member | Only if you have a UMID card | Only if you’ve applied for one |
SSS Number: Your Original Membership Number
Your SSS number is a 10-digit number assigned when you first register as an SSS member. It’s used specifically for transactions within SSS — contributions, loans, benefit claims — and it’s the number most older members are used to, since it predates the CRN/UMID system.
CRN (Common Reference Number): The Shared Government ID
The CRN is a 12-digit number, printed in the format ####-#######-#, that links your identity across four government agencies at once: SSS, GSIS, PhilHealth, and Pag-IBIG. It was introduced to let these agencies share and cross-reference member data more easily.
The important catch: not everyone has a CRN. You’re only issued a CRN when you apply for a UMID card. If you’re an SSS member but haven’t applied for a UMID yet, you likely don’t have a CRN — and that’s completely normal, not an error on your part.
UMID (Unified Multi-Purpose ID): The Physical Card
The UMID is the actual plastic ID card that replaced the old blue SSS ID. It’s valid for life — no expiry date — and serves as a recognized government ID for banks, employers, and transactions across all four linked agencies. Your CRN is printed on the upper-right portion of this card, and also functions as the card’s own ID number.
Which One Should You Actually Use?
This is the part most explainers skip. Here’s the practical answer for common situations:
- Registering for My.SSS online — you can use either your SS Number or CRN, whichever you have. If you have a UMID, your CRN works fine here.
- Checking contributions or applying for a loan through My.SSS — once registered, the system tracks your record regardless of which number you used to sign up, so this isn’t something you need to worry about after registration.
- Employer forms, bank applications, other agency transactions — if a form specifically asks for a CRN and you don’t have one, provide your SSS number instead, unless the form explicitly requires a UMID-linked CRN (uncommon, but happens with some inter-agency transactions).
- If a form asks for “SSS Number/CRN” together — this usually means either works; provide whichever you have.
Don’t Have a CRN or UMID Yet?
If you don’t have a UMID card (and therefore no CRN), you can apply for one at any SSS branch. You’ll need:
- A valid primary ID (passport, driver’s license, or similar), or two valid secondary IDs if you don’t have a primary one
- Your SSS number
- Biometric capture (fingerprints and photo) done in-branch
Processing and release times vary by branch and current volume — check with SSS directly or your nearest branch for current estimated timelines.
FAQs
Is my CRN the same as my SSS number, just reformatted? No — they’re genuinely different numbers (10 digits vs. 12 digits), not the same number displayed differently. The CRN is a separate identifier layered on top of your existing SSS number.
Can I have a UMID without a CRN, or a CRN without a UMID? No — the CRN is issued specifically as part of the UMID application process, so the two go together. You can’t have one without the other.
Does everyone eventually get switched over to CRN instead of SSS number? No — your SSS number remains your permanent SSS identifier regardless of whether you also have a CRN. The CRN is an additional cross-agency identifier, not a replacement for your SSS number within SSS’s own system.
I lost my UMID card — do I lose my CRN too? No, your CRN remains tied to your record even if the physical card is lost. You’d need to apply for a UMID card replacement to get a new physical card, but the number itself isn’t lost.
