Credit cards are a common example of ISO/IEC 7810 ID-1 sized cards.

ISO/IEC 7810 Identification cards — Physical characteristics is an international standard that defines the physical characteristics for identification cards.[1]

The characteristics specified include:

  • Physical dimensions
  • Resistance to bending, flame, chemicals, temperature and humidity
  • Toxicity

The standard includes test methods for resistance to heat.[2]

Card sizes

The standard defines four card sizes: ID-1, ID-2, ID-3 and ID-000.[3]

Format Dimensions Usage
ID-1 85.60 × 53.98 mm Most banking cards and ID cards
ID-2 105 × 74 mm French and other ID cards; Visas
ID-3 125 × 88 mm Passports
ID-000 25 × 15 mm SIM cards

All card sizes have a thickness of 0.76 mm (0.030 in).

The standard defines both metric and imperial measurements, noting that:[4]

Numeric values in the SI and/or Imperial measurement system [...] may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should not be intermixed or reconverted. The original design was made using the Imperial measurement system.


The ID-1 format specifies a size of 85.60 × 53.98 mm (3.370 × 2.125 in) and rounded corners with a radius of 2.88–3.48 mm. It is commonly used for banking cards (ATM cards, credit cards, debit cards, etc.). Today it is also used for driving licences in many countries. This format is also used for personal identity cards in some countries, automated fare collection system cards for public transport, in retail loyalty cards, and it is one fairly common format for business cards.[citation needed]. Both the recently issued Irish and much older U.S. passport cards, Crew Member Certificates (particularly for aircrew[5]), as well as most National identity cards in the European Economic Area also use the ID-1 format.


The ID-2 format specifies a size of 105 × 74 mm (4.134 × 2.913 in). This size is the A7 format. The ID-2 format is used, for example, for visas. It is used for the French identity card, and was also used by the German identity card issued until October 2010. Since November 2010, German ID cards are issued in the ID-1 format more widely used in Europe for national ID cards.


ID-3 specifies a size of 125 × 88 mm (4.921 × 3.465 in). This size is the B7 format. This format is commonly used for passport booklets.[citation needed]


ID-000 specifies a size of 25 mm × 15 mm, with one corner slightly (3mm) bevelled. The ID-000 size was first defined by ENV 1375-1, Identification card systems — Intersector integrated circuit(s) card additional formats — Part 1: ID-000 card size and physical characteristics.

This size is used for the "mini-SIM" format of subscriber identity modules.

ID-000 size card as part of ID-1 size card

An "informative" (i.e. non-mandatory) annex[6] describes how an ID-000 sized card may be included in an ID-1 size card for processing (e.g. in an ID-1 reader), but with "relief areas around the perimeter of the ID-000 size card to allow it to be removed from the ID-1 size card without punching tools". An ID-1 size card containing an ID-000 size card is denoted as ID-1/000.

Card characteristics

The standard specifies requirements for such physical characteristics as:[7]

  • Bending stiffness
  • Flammability
  • Toxicity
  • Resistance to chemicals
  • Card dimensional stability and warpage with temperature and humidity
  • Resistance to deterioration from exposure to light and heat
  • Durability
