Code Components

1. Product Type (NV)

• Position: 1-2
• Value: NV
• Product: Unit admission notification
• Product Code: POAXAC
• Available methods:
  • NTAPEU

2. Labeler Code (EEEE)

• Position: 3-6
• Format: 4 alphanumeric characters
• Observation: Provided by the commercial department

• Position: 7-8
• Fixed value: 98
• Meaning: Indicates that the preregistration channel is API

4. Client Numbering (00000000000001)

• Position: 9-22
• Format: 14 numeric digits
• Characteristics:
  • Must not be repeated in 5 years
  • If exhausted, requires labeler change
  • Maximum capacity: 99,999,999,999,999

5. Control Digit (A)

• Position: 23
• Format: 1 alphabetic character
• Calculation: See 'Control digit calculation' for the calculation formula

Control Digit Calculation

The letter of the control character is obtained from the following formula, which involves the first 22 characters of the shipping code:

The ASCII value corresponding to the character (in uppercase) occupying each of the 22 positions is obtained.

All the obtained values are summed.

0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22
T  R  W  A  G  M  Y  F  P  D  X  B  N  J  Z  S  Q  V  H  L  C  K  E

The result of the sum is divided by 23. The remainder of the division is a number between 0 and 22, which will indicate the letter to be used as the control character, within the following table, which is the same used for the calculation of the NIF:

Example:

The initial string of 22 characters, to which the control character must be added, is as follows:

PE08000536165000755542.

Obtaining the ASCII values of each position:

The sum of all ASCII codes is 1171.

The remainder of the division of 1171 by 23 is 21.

The letter assigned to this position, according to the table, is K.

The complete shipping code would be PE08000536165000755542K.
