Series administration in electronic documents (DE) of Colombia.
::: tip
A. Series Administration
:::
-
Range start:
- Use standard numbering (without series) from 1 to 9999999 (nine million nine hundred ninety-nine thousand nine hundred ninety-nine) for each document type.
-
Range end:
- When standard numbering is exhausted, activate the use of series.
- Define the series with combinations of two uppercase letters (excluding Ñ).
- Practical Example: Start with Series AA.
-
Document types:
- Establish a default series order: AA, AB, AC, ..., AZ, BA, BB, ..., BZ, ..., ZA, ZB, ..., ZZ.
- Validate sequentiality according to this order.
- Practical Example: After AA, use AB, AC, and so on.
-
Resolution number:
- When receiving a DE with series, take the digital signature date and time as the initial date of the corresponding series.
-

Technical key:

Series:

Term:
-
Approve DE under the following conditions:
- Immediately preceding series: DE with a series prior to the highest series submitted to the system, with a digital signature date prior to the start date of the current series' validity.
- Equal series: DE with a series equal to the highest series submitted to the system.
- Immediately subsequent series: DE with a series after the highest series submitted to the system, with a digital signature date after the start date of the current series' validity.
-
::: tip
B. Additional Considerations and Controls
:::
- Series Integrity: Validate that the assigned series has not been used previously to avoid duplicates.
- Record of Used Series: Maintain a historical record of all used series for audit and traceability.
- Standard Numbering Exhaustion Notification: Alert when standard numbering is nearing exhaustion to prepare for the transition to series.
- Sequentiality Maintenance: Implement controls to ensure correct sequentiality within each assigned series.
- Audit of Used Series: Conduct periodic audits to ensure continued compliance with regulations and the validity of used series.
