What is the Europe ID card code? (Definition)

At the bottom of the European identity card is an optically readable strip written in black on a white background, which presents all the information of the card in a structured format.

What does the European ID card code mean? (2021 version)

The European version 2021 of the European identity card consists of three lines of 30 characters each, making a total of 90 characters. The first line starts with the 2 letters ID, followed by the country code, here is in detail:

PositionMeaning of content
1-2Always the 2 letters ID (for IDentity)
3-53-letter (ISO3166) country code
6-14Official card number (composed of 9 alphanumeric characters A-Z0-9)
15Checksum digit for Card number
16-30Empty/Reserved/Not used (filled with <)

Example: ID FRA 123456789 X ‹‹‹‹‹‹‹‹‹‹‹‹‹‹‹

The date of birth is the first information on the second line, followed by the sex and the expiry date.

PositionMeaning of content
1-2Year (2 digits) of birth
3-4Month (2 digits) of birth
5-6Day (2 digits) of birth
7Checksum for 6-digit birthdate
8Sex (M or F)
9-10Year (2 digits) of expiry of the card
11-12Month (2 digits) of expiry

What is the number of the Europe ID card?

The identity card number consists of 9 alphanumeric characters and corresponds to the characters located between the 6th and the 14th position of the first line.

Example: DOCUMENT NUMBER XXXXXXXXXX

How to calculate checksums?

To calculate the checksum, each character is associated with a numerical value ranging from 0 for the character , 1 for 1 to 9 for 9, 10 for A , 11 for B, and so on up to 35 for Z.

Each character must be multiplied by a factor chosen from three values: 7 for the first character, 3 for the second, 1 for the third, 7 for the fourth, 3 for the fifth, and and so on.

Add all the numbers obtained and retain the last digit corresponding to the units of the result. This number is the control key (checksum).

Example: Calculate the checksum key for DCODE1<, the sum is calculated 91+36+24+91+42+1+0=285 and then the key is 5 :

D13*7=91Σ=91
C12*3=36Σ=127
O24*1=24Σ=151
D13*7=91Σ=242
E14*3=42Σ=284
11*1=1Σ=285
0*7=0Σ=285

How to generate a fake ID card?

The dCode generator only uses public data, without internal numbers and codes provided by the administration. It should be remembered that the use of a false document or a false identity card is punishable by a prison sentence of 5 years and a minimum fine of 75000€.
