Tool note: figures are based on the official CR80/ISO 7810 ID-1 specification (85.60 × 53.98 mm) and publicly documented dimensions for each comparison card. This is a reference tool, not an official PSA measurement service.

Why the PhilID Uses the CR80 Standard

Every PhilSys card traces its dimensions back to one international spec: ISO/IEC 7810 ID-1, more commonly called CR80 in the card-printing industry. It’s the same designation that governs your bank card, most driver’s licenses worldwide, and the majority of national ID programs outside the Philippines.

The Philippine government didn’t pick this size arbitrarily. Republic Act No. 11055, which created PhilSys, effectively locks the PhilID into a format that already has global infrastructure built around it:

• Wallet compatibility — every card slot manufactured for a bank card already fits the PhilID. No special sleeve or holder needed.
• Reader compatibility — card readers at banks, airports, and government counters are already built for CR80 dimensions.
• Cross-border verification — because most countries’ national IDs share this format, the PhilID is legible to systems built for other countries’ cards too, which matters for OFWs and dual-use verification.

CR80 vs. CR79 vs. CR100: Full Format Comparison

If you’re designing or sourcing ID cards rather than just checking your PhilID, here’s how the three formats you’ll encounter most often actually differ:

A CR79 card will sit loosely in a wallet slot built for CR80. A CR100 card won’t fit a standard slot at all. CR80 is the only one of the three built specifically around everyday carry, which is exactly why it’s the default for government-issued ID worldwide.

What’s Actually Printed on the Card

Knowing the layout helps you both use the card correctly and recognize a genuine one.

Front of the PhilID

The front carries the Republic of the Philippines coat of arms, the PSA logo, and your 16-digit PhilSys Card Number (PCN) at the bottom. Your photo, full name, date of birth, and address are laser-engraved rather than printed — along with guilloche patterns, microprinting, and color-shifting ink as anti-counterfeiting measures. Unlike most other Philippine government IDs, the PhilID does not carry a handwritten signature.

Back of the PhilID

The back holds a scannable QR code, your sex, blood type, optional marital status, place of birth, date of issue, and a serial number. Your permanent 12-digit PhilSys Number (PSN) is not printed in full — it’s embedded in microprint and encoded in the QR code.

Card Thickness & Material

Thickness in the card industry is measured in mils (thousandths of an inch). The PhilID sits at the standard 30 mil — the same as most bank cards — but the material underneath is different.

The PhilID uses polycarbonate, not the PVC found in most bank cards. Polycarbonate is stiffer and more tamper-resistant at the same thickness — it’s why the card feels less flexible than a typical credit card even though the numbers match.

National ID Size vs. Other Philippine Government IDs

Three Formats, One Size Rule: Physical Card, ePhilID, and Digital ID

PhilSys issues the National ID in three formats, and only one of them follows a fixed physical size:

• Physical PhilID card — the polycarbonate CR80 card delivered by PHLPost. This is the primary, fixed-size format.
• ePhilID — a paper printout on standard A4/letter security paper, issued right after biometric capture. Considerably larger than the card; some people laminate and trim theirs, though PSA doesn’t officially recommend it.
• Digital National ID (via the eGovPH app) — no fixed size at all. It renders to fit whatever screen it’s displayed on, with a dynamic QR code for real-time verification.
