ISO/IEC 7810


ISO/IEC 7810 Identification cardsPhysical characteristics is an international standard that defines the physical characteristics for identification cards.
The characteristics specified include:
  • Physical dimensions
  • Resistance to bending, chemicals, temperature, and humidity
  • Toxicity
The standard includes test methods for resistance to heat.

Card sizes

The standard defines four card sizes: ID-1, ID-2, ID-3 and ID-000.
All card sizes have a thickness of, i.e. minimum and maximum.
The standard defines both metric and imperial measurements, noting that:

ID-1

The ID-1 format specifies a size of and rounded corners with a radius of 2.88-3.48 mm. This format is also referred to as CR-80 and, for travel documents, TD1. It is commonly used for payment cards. Today it is also used for driving licences and personal identity cards in many countries, automated fare collection system cards for public transport, in retail loyalty cards, and even crew member certificates. As of 2024, all [National Identity document|identity cards in the European Economic Area|European standard] identity cards are issued in the ID-1 format.

ID-2

The ID-2 format is, and travel documents in this format are also referred to as TD2. This length and width are those of A7 paper. The ID-2 format is used, for example, for visas. It was previously used for the Romanian, Icelandic, German, French and many other identity cards. ID-2 was previously also used for driving licences before those changed to the ID-1 format.

ID-3

The ID-3 format is, and travel documents in this format are also referred to as TD3. This length and width are those of B7 paper. This format is commonly used for passport booklets.

ID-000

ID-000 specifies a size of, with one corner slightly bevelled. The ID-000 size was first defined by ENV 1375–1, Identification card systems — Intersector integrated circuit card additional formats — Part 1: ID-000 card size and physical characteristics.
This size is used for the mini-SIM format, the second-generation format of Subscriber Identity Modules.

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

An "informative" annex describes how an ID-000 sized card may be included in an ID-1 size card for processing, 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. This was the common design of SIMs when mini-SIMs were common, usually being issued as standard SIMs, i.e. in ID-1 format, with a removable ID-000 section that, when removed, was a mini-SIM.

Card characteristics

The standard specifies requirements for such physical characteristics as:
  • Bending stiffness
  • Toxicity
  • Resistance to chemicals
  • Card dimensional stability and warpage with temperature and humidity
  • Resistance to deterioration from exposure to light and heat
  • Durability
