Trying to find your CRN in the Philippines can be confusing because different agencies use different numbers: SSS number, PhilHealth PIN, Pag-IBIG MID, GSIS BP number, National ID number, transaction reference number, and CRN. In most Philippine government ID and SSS contexts, CRN means Common Reference Number — the 12-digit number linked to the old UMID system. This guide explains where to find your CRN, how it differs from your SSS number and National ID number, what to do if you do not have a UMID card, and how to retrieve it safely through official channels.

What Is a CRN in the Philippines?

A CRN, or Common Reference Number, is the number associated with the Unified Multi-Purpose ID system, commonly called UMID.

The UMID system was designed to harmonize identification records among major government agencies, especially:

Social Security System (SSS)
Government Service Insurance System (GSIS)
Philippine Health Insurance Corporation (PhilHealth)
Home Development Mutual Fund (Pag-IBIG Fund)

For many ordinary users, the CRN appears in one of these places:

On an old SSS-issued or GSIS-issued UMID card
In a My.SSS member account, if a CRN is already on file
In records connected with a prior UMID application
In agency systems that still recognize UMID-linked information

The CRN is not the same as your SSS number. Your SSS number is the number used for SSS contributions, loans, benefits, and employer reporting. Your CRN is a separate identifier connected with the UMID/common ID system.

CRN vs SSS Number vs National ID Number

Many people search “how to find my CRN” when they actually need a different number. Before you spend time retrieving the wrong identifier, check what the agency or form is really asking for.

Number	Usual format or description	Main use	Where you usually find it
CRN	Usually 12 digits, often printed as groups on a UMID card	UMID-linked identification	UMID card, My.SSS account if available, agency record
SSS Number	10 digits, commonly formatted like `##-#######-#`	SSS contributions, benefits, loans, employment reporting	SSS number slip, E-1/E-6, My.SSS, employer records
PhilHealth PIN	PhilHealth Identification Number	PhilHealth membership and benefits	PhilHealth MDR, Member Portal, PhilHealth ID
Pag-IBIG MID	Pag-IBIG Membership ID	Pag-IBIG contributions, loans, MP2	Pag-IBIG Virtual Account, MDF, employer records
GSIS BP Number	Business Partner number	GSIS transactions for government employees and pensioners	GSIS records, eGSISMO/GSIS Touch
National ID Number / PSN	12-digit unique number under PhilSys	National ID system	PSA/National ID records, subject to privacy safeguards
TRN	Transaction Reference Number	Tracking a specific application, especially National ID or SSS online registration	Transaction slip or confirmation email

A common mistake is treating the National ID number as the same thing as the UMID CRN because both may involve 12 digits. They are different systems. The National ID system is governed by Republic Act No. 11055, or the Philippine Identification System Act, while the UMID/CRN system came from the earlier unified ID framework under Executive Order No. 420.

Legal Basis for the CRN and UMID System

The Philippine legal basis for the CRN comes mainly from Executive Order No. 420, series of 2005, which directed government agencies and government-owned or controlled corporations that issue IDs to adopt a unified multi-purpose ID system.

EO 420 required participating agencies to streamline ID systems and provided that a common reference number would form part of the stored ID data and appear on the ID card for verification purposes. You can read the text of the order on Lawphil: Executive Order No. 420, s. 2005.

The Supreme Court discussed this system in Kilusang Mayo Uno v. Director-General, National Economic and Development Authority, G.R. Nos. 167798 and 167930, April 19, 2006. The Court upheld EO 420, explaining that it did not create a compulsory national ID system for all citizens but harmonized existing ID systems of agencies already issuing IDs. The decision also emphasized privacy safeguards and limits on the data that may be collected. The decision is available through the Supreme Court E-Library: Kilusang Mayo Uno v. Director-General, NEDA.

This matters because your CRN is still personal information. Under Republic Act No. 10173, or the Data Privacy Act of 2012, government agencies and private entities must process personal data lawfully, fairly, and securely. The National Privacy Commission publishes the law here: Data Privacy Act of 2012.

The Fastest Ways to Find Your CRN

1. Check Your UMID Card

If you already have a UMID card, this is usually the fastest method.

Look for the number labeled CRN on the face or back of the card. It is commonly printed in a grouped format, such as:

####-#######-#

Do not confuse it with:

Your SSS number
Your GSIS BP number
Your bank account number, if your UMID is also an ATM or debit card
The card number of a bank-issued card

If you are submitting your CRN online, type only the numbers unless the system specifically asks you to include hyphens.

2. Log In to Your My.SSS Account

If you are an SSS member, your My.SSS account may show both your SS number and CRN number, if a CRN is already attached to your record.

Use the official My.SSS portal only: My.SSS Member Portal.

General steps:

Go to the official My.SSS portal.
Log in using your User ID and password.
Check the main member page, profile, member information, or account details section.
Look for a field labeled CRN Number.
Copy the number exactly as shown.

SSS’s own My.SSS registration guide shows that after successful account setup, the member page may display both the SS Number and CRN Number. The official PDF guide is here: My.SSS Member Registration Guide.

If your My.SSS account shows only your SS number and no CRN, it may mean no CRN has been generated or linked to your account, especially if you never applied for or received a UMID card.

3. Use Your SS Number If the Form Says “CRN / SS Number”

Some SSS pages and forms ask for “CRN / SS Number.” This does not always mean you must have both.

For example, the My.SSS registration page asks for CRN / SS Number, and the official SSS registration guide instructs users to enter their CRN or SS number when creating a My.SSS account. If you do not know your CRN, your SS number is usually the correct number to enter for SSS transactions.

This is especially common for:

Creating a My.SSS account
Resetting portal access
Verifying SSS membership details
Accessing contribution records
Generating payment reference numbers

4. Check Old SSS Emails and Documents

If you applied for an SS number online, check your email for messages from SSS, especially the SS Number Online Application Confirmation.

You may find:

SS Number Slip
Transaction Number Slip
E-1/E-6 form
Personal Record / UMID application form

Be careful: the transaction number is not the same as your CRN. It may help you register or recover access to your My.SSS account, but it is not your Common Reference Number.

SSS explains its online SS number process on its official page: Become an SSS Member.

5. Ask SSS Through Official Channels

If you cannot access My.SSS, your card is lost, or your record has inconsistent information, use official SSS channels.

Practical options include:

Visiting an SSS branch with valid IDs
Using the official uSSSap Tayo / CRMS portal: SSS uSSSap Tayo
Checking the official SSS website for branch and service updates: SSS website

Do not post your full name, birth date, SS number, CRN, UMID photo, or ID selfie in public comment sections. An official FOI response involving a CRN/SS number request noted that FOI does not cover requests that disclose member information and advised the member to use SSS’s official portal instead: FOI request on CRN/SS Number.

What If You Do Not Have a UMID Card?

If you never applied for a UMID card, you may not have a CRN available to you. This is common among:

New SSS members
Prior registrants with no UMID application
Employees whose employer registered them with SSS but who never applied for UMID
OFWs who only created an SSS number online
Members who use the National ID instead of UMID

In that case, use your SS number for SSS transactions.

The old regular UMID process has also changed in practice. SSS now describes the MySSS Card as the new official functional ID issued by SSS, equipped with an EMV chip and replacing the old UMID card. SSS also states that previously issued SSS cards, including UMID cards, remain valid, but the National ID now serves as the primary official identification for Filipinos. You can review the official SSS page here: MySSS Card.

For general identification, especially with government offices and private institutions, the more current route is usually:

National ID
Digital National ID
ePhilID / National ID in paper format
Passport
Driver’s license
Other accepted government-issued ID

The Philippine Statistics Authority explains the National ID system, its formats, and its validity here: National ID FAQs.

Step-by-Step Guide: How to Find Your CRN

If You Have a UMID Card

Get your UMID card.
Look for the label CRN.
Write the number exactly as printed.
Keep a private copy in a secure place.
Do not send a photo of the card unless the receiving agency is official and the transaction requires it.

If You Have a My.SSS Account

Go to My.SSS.
Log in.
Check the dashboard, member profile, or member information page.
Look for CRN Number.
If no CRN appears, use your SS number for SSS transactions unless the office specifically asks for CRN.

If You Forgot Your My.SSS Login

Go to the My.SSS portal.
Use the account recovery options.
Prepare your SS number, registered email, registered mobile number, and identifying details.
If the system does not recognize your information, your SSS record may have outdated contact details.
Visit an SSS branch or use the official SSS assistance portal to update or verify your record.

If You Lost Your UMID Card

Try to retrieve the CRN through My.SSS first.
If you cannot access My.SSS, prepare valid IDs and go through SSS verification.
If you need a replacement card or updated SSS card, check the current MySSS Card process rather than relying on older UMID instructions.
Expect bank-related verification if applying for a MySSS Card through an SSS partner bank.

Under the MySSS Card process, SSS states that members must have a permanent SS number, be registered on the My.SSS portal, have updated contact details and local address in SSS records, and be PSA/National ID registered. SSS also notes that the partner bank produces and releases the card, with stated release periods of 15 working days in Metro Manila and 20 working days outside Metro Manila after successful account opening, subject to the bank process.

If You Are a Government Employee or GSIS Pensioner

If your UMID came from GSIS, check your physical UMID/eCard records or GSIS online channels.

GSIS has been moving many services to GSIS Touch and the GSIS Digital ID. The GSIS Touch page says users can access the GSIS Digital ID and personal records through the official app: GSIS Touch.

Do not confuse your GSIS BP Number with your CRN. The BP number is used for GSIS transactions; the CRN is connected with the UMID/common ID system.

Documents You May Need to Retrieve or Verify Your CRN

The exact requirements depend on the agency and the transaction, but these are commonly useful:

Situation	Documents usually needed
Accessing My.SSS	SS number or CRN/SS number, registered email, registered mobile number, login credentials
Branch verification	One primary valid ID, or two secondary IDs if no primary ID is available
Correcting name or birth date	PSA birth certificate, passport, marriage certificate if applicable, or supporting IDs
Foreign-issued documents	Official English translation if needed; apostille or consular authentication when required
Representative filing	Authorization letter, valid IDs of owner and representative; SPA or LOA when required
Lost card	Valid ID, account verification, and current SSS/GSIS replacement or digital ID process

SSS’s own guidance for member record updates lists primary IDs such as UMID, Philippine Identification Card, Alien Certificate of Registration, driver’s license, NBI clearance, passport, postal ID, and voter’s ID. It also notes that foreign government-issued documents in foreign languages should have an official English translation by the Philippine Embassy or Consulate.

For documents signed or issued abroad, the practical issue is usually authentication. The DFA’s Apostille Appointment System states that DFA Aseana and DFA consular offices with authentication services accept applicants through online appointment: DFA Apostille Appointment System.

Common Problems When Finding Your CRN

Your My.SSS Account Shows Only Your SS Number

This usually means your SSS record exists, but a CRN may not be linked or displayed. Continue using your SS number for SSS transactions unless the specific transaction requires a UMID-linked CRN.

Your Name or Date of Birth Does Not Match

This is one of the most common bottlenecks. Even a small mismatch can block online verification.

Examples:

“Maria Cristina” in PSA records but “Ma. Cristina” in SSS
Married name in one record but maiden name in another
Wrong birth date encoded by an employer
Missing middle name
Foreign name order entered incorrectly

Fix the record with the agency holding the incorrect data. Do not simply create a new SSS number. Multiple SSS numbers can create serious problems with contributions, benefits, and claims.

You Have a Temporary SS Number

An SS number tagged as temporary may be used for contributions, but you may need to submit supporting documents to make it permanent before you can fully access benefits or certain services. SSS’s member guidance explains that a temporary SS number must be changed to permanent by submitting proper documents, such as a PSA-issued birth certificate or other accepted primary documents.

You Are an OFW Abroad

If you are abroad, start online:

Check My.SSS.
Search your email for SSS confirmation messages.
Use SSS online assistance channels.
If documents must be signed abroad, check whether they need notarization before a Philippine Embassy or Consulate, or apostille depending on the document and country.

For representative transactions in the Philippines, SSS guidance provides that a Letter of Authority or Special Power of Attorney may be required for transactions filed by a representative. Pay attention to validity periods because documents signed in the Philippines and documents signed abroad may be treated differently.

You Are a Foreigner in the Philippines

Foreign nationals usually encounter CRN issues only if they have Philippine social security or government ID records, such as SSS coverage due to employment or other covered status.

For identity verification, foreigners commonly use:

Passport
Alien Certificate of Registration Identity Card (ACR I-Card)
Work-related permits, where applicable
Foreign government ID, if accepted for that specific transaction
National ID, if the person is a resident alien registered under PhilSys

A resident alien may be eligible for the National ID system under RA 11055, but that is separate from the UMID CRN.

Fees and Timelines

Transaction	Usual fee	Practical timeline
Viewing CRN on UMID card	None	Immediate
Viewing CRN through My.SSS	None	Immediate if you can log in
Recovering My.SSS access	None	Minutes to days, depending on whether your email/mobile matches SSS records
Branch verification	Usually none for inquiry/verification	Same day if records and IDs are complete; longer if correction is needed
Old UMID replacement/update	Older SSS guidance mentioned replacement fees; check current SSS process	Varies
MySSS Card	Bank may charge card/account-related fees	SSS states 15 working days in Metro Manila and 20 working days outside Metro Manila after successful bank account opening
Record correction	Usually none for basic filing, but supporting documents may have costs	Days to weeks depending on discrepancy and document completeness
Apostille/authentication for documents	DFA appointment system states an appointment fee that includes one document	Depends on appointment availability and release schedule

The biggest delay is usually not the CRN itself. It is usually one of these:

Inactive or inaccessible My.SSS account
Old mobile number or email in SSS records
Name mismatch between SSS and PSA/National ID records
Lost UMID card with no online access
Temporary SS number
Documents signed abroad without proper authentication

Safety Tips: Protect Your CRN and Government ID Numbers

Treat your CRN like other personal identifiers. It may not be as sensitive as a password or OTP, but it can still be misused together with your name, birth date, address, and ID photo.

Follow these rules:

Do not post your CRN, SS number, UMID card, or ID selfie in public groups.
Do not give your My.SSS password or OTP to anyone.
Do not transact with fixers who promise faster SSS, UMID, or National ID processing.
Use only official websites ending in .gov.ph where possible.
Be careful with sponsored pages, fake “SSS assistance” accounts, and private individuals asking for screenshots.
If you must send a document to an official office, send only through the official channel and keep proof of transmission.

The privacy concern is not theoretical. The Supreme Court’s national ID cases, including Ople v. Torres and Kilusang Mayo Uno v. Director-General, NEDA, show that Philippine law recognizes the importance of safeguards when government identifiers and personal data are collected and used.

Frequently Asked Questions

How do I find my CRN number online?

Log in to your official My.SSS account and check your member profile or account details. If SSS has a CRN linked to your record, it may appear as CRN Number. If no CRN appears, use your SS number for SSS transactions unless the form specifically requires a CRN.

Is my CRN the same as my SSS number?

No. Your SSS number is used for SSS contributions, benefits, loans, and employer reporting. Your CRN is the Common Reference Number connected with the UMID system. Some SSS forms say “CRN / SS Number” because either number may be accepted for that particular SSS login or registration process.

Can I find my CRN without a UMID card?

Possibly, if your CRN is already linked to your My.SSS or GSIS record. Try My.SSS first. If no CRN appears and you never applied for UMID, you may not have a CRN available. In that case, your SS number is usually the number you need for SSS transactions.

Where is the CRN located on the UMID card?

It is usually printed on the UMID card and labeled CRN. It may appear as a 12-digit number grouped with hyphens. Do not confuse it with your SSS number or bank card number.

What if My.SSS says “CRN / SS Number” and I do not know my CRN?

Enter your SS number. SSS’s own registration process recognizes “CRN / SS Number,” and many members register or log in using their SS number.

Is the CRN the same as the National ID number?

No. The CRN belongs to the UMID/common ID framework. The National ID number belongs to the Philippine Identification System under RA 11055. They are different even if both may involve 12 digits.

Can SSS give my CRN through email or public FOI request?

SSS generally should not disclose member-specific information through public channels. Use secure official channels such as My.SSS, SSS branch verification, or the official SSS assistance portal. Avoid posting your personal information online.

Do I still need a CRN if I already have a National ID?

For most identity verification, the National ID, Digital National ID, or ePhilID is now more important. But some older records, SSS forms, or UMID-linked transactions may still refer to the CRN. If the transaction is purely SSS-related, your SS number is often enough.

Can a foreigner have a CRN in the Philippines?

A foreigner may encounter CRN-related records only if they are covered by a Philippine agency system that issued or linked a UMID/CRN record. For most foreign nationals, identity verification usually relies on passport, ACR I-Card, work-related documents, and, for resident aliens registered under PhilSys, the National ID system.

Key Takeaways

CRN means Common Reference Number and is usually connected with the UMID system.
The fastest way to find your CRN is to check your UMID card or your My.SSS account.
Your CRN is not the same as your SSS number, PhilHealth PIN, Pag-IBIG MID, GSIS BP number, or National ID number.
If an SSS form asks for “CRN / SS Number,” you can usually use your SS number if you do not know your CRN.
If you never applied for or received UMID, you may not have a CRN linked to your record.
Old UMID cards remain valid, but SSS now points members to the MySSS Card process, while the National ID is the main general-purpose ID.
Do not retrieve your CRN through fixers, public comment threads, or unofficial pages.
If your records do not match, fix the underlying name, birth date, or contact information issue with the proper agency first.
