SSS Number vs. CRN vs. UMID: What's the Difference?

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.

Important update: the UMID now has a successor. On October 1, 2025, SSS launched the MySSS Card, which SSS describes as its new official functional ID with an EMV chip, replacing the UMID. Your existing UMID and other old SSS cards remain valid. Secondary guides also report that SSS is no longer issuing new generic UMID or UMID Pay cards. One caution from SSS itself: the MySSS Card is valid for SSS transactions, but other government agencies and private institutions aren’t required to accept it as an official ID, since the National ID (PhilSys) is now the primary official ID.

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?

SSS’s guidance has shifted. The UMID is no longer the main path for new applicants; SSS now issues the MySSS Cardthrough partner banks, and describes it as the replacement for the UMID.

To qualify, SSS says you need:

An SS number tagged as “permanent”
A registered My.SSS account
An up-to-date local address, mobile number and email in SSS records
A PSA/National ID (PhilSys) registration, with your name and date of birth matching in both your SSS and National ID records

You apply in two steps. First, in My.SSS (Services > MySSS Card), you consent to National ID verification, complete a facial scan and choose a partner bank. Then the bank opens your account and issues the card. SSS uses your National ID photo, so you don’t need biometrics at an SSS branch. The bank may charge a card fee.

What we couldn’t confirm: whether the MySSS Card carries a CRN the way the UMID did. If a form specifically requires a CRN, check your SSS records or ask SSS directly. Your SSS number continues to work for SSS transactions in the meantime.ard carries a CRN the way the UMID did. If a form specifically requires a CRN, check your SSS records or ask SSS directly.

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. SSS says you can apply for a MySSS Card to replace a lost or damaged card, though we couldn’t confirm whether it shows your CRN. The number itself isn’t lost.
