2- Association of billing prefixes (numbering ranges) in the DIAN
Step 1: Access the DIAN website at https://www.dian.gov.co, and then, in the “Topics of Interest” section, under “Electronic Invoicing,” click on the option that says “Electronic Billing”.

Step 2: Next, select the type of user you registered with at DIAN (company or individual), enter the information requested by the system, and click the “Enter” button.

Step 3: Upon completing the data, the DIAN system will send an email to the address registered in the RUT with an access link (if it is a company, the email will be sent to the personal email registered in the NIT of the legal representative). The email is similar to the following.

Step 4: Once you access the DIAN enablement panel, go to the menu on the left side and click on Configuration > Numbering Ranges.

Step 5: Once in the Numbering Ranges section, you must select “EMPRESA DE DIVULGACIONES Y ASESORÍAS ECA SAS” under Provider – Software, and under Prefix, select the resolution number you previously authorized in the DIAN. Then click on Add.
