How to verify an EID

Where is it specified

Annex J of SPG.02 provides a description of how to verify an EID.

Verification algorithm

Verification of an EID is performed as follows:

• Using the 32 digits as a decimal integer, compute the remainder of that number on division by 97.
• If the remainder of the division is 1, the verification is successful; else the EID is invalid.

As an example in C using the modulus operator %, returns the remainder:

if (EID % 97 == 1)
{
    //EID valid
}
else
{
    //EID invalid
}

Example

EID example= 89034011560010000000000000000121

89034011560010000000000000000121 % 97 = 1 -> EID valid

Examples of valid EIDs are:

• 8900 1012 0123 4123 4012 3456 7890 1224
• 8900 1567 01020304 0506 0708 0910 1152
• 8904 4011 1122 3344 1122 3344 1122 3321
