It is described in US patent 2950048A, granted on 23 August 1960. [1]
A prominent user is the European Health Insurance Card system, which appends 5 digits of insurer identification (essentially making a 10-digit IIN-alike system.) 89 EE(E) Telecommunications use, administered by the ITU-T. SIM card ICCIDs are allocated from this range. EE(E) refers to the E.164 country code (with some exceptions.) 9 CCC
All citizens over the age of 16 need to apply for a National Identity Card (NIC). Each NIC has a unique 10 digit number, in the format 000000000A (where 0 is a digit and A is a letter). The first two digits of the number are your year of birth (e.g., 88xxxxxxxx for someone born in 1988). The final letter is generally a V or X. An NIC number is ...
For example, the combination "12-1" is the letter "A" in an alphabetic column, a plus signed digit "1" in a signed numeric column, or an unsigned digit "1" in a column where the "12" has some other use. The introduction of EBCDIC in 1964 defined columns with as

[4] [1] A smartphone or smartwatch can store content from the card issuer; discount offers and news updates can be transmitted wirelessly, via Internet. These virtual cards are used in very high volumes by the mass transit sector, replacing paper ...
An "informative" (i.e. non-mandatory) annex [7] 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 ...
The digit the farthest to the right (which is multiplied by 1) is the check digit, chosen to make the sum correct. It may need to have the value 10, which is represented as the letter X. For example, take the ISBN 0-201-53082-1: The sum of products is 0×10 + 2×9 + 0×8 + 1×7 + 5×6 + 3×5 + 0×4 + 8×3 + 2×2 + 1×1 = 99 ≡ 0 (mod 11). So ...
