Yes, provided you use a legitimate route, hold the data subject's authorisation, respect the permitted hours for advertising and honour opt-outs and the excluded-numbers register. Rules come from Law 2300 of 2023, Law 1581 of 2012, the CRC and the operators. ### What hours can I send advertising SMS in Colombia? Law 2300 of 2023 limits advertising SMS to Monday to Friday between 07:00 and 19:00 and Saturday between 08:00 and 15:00, never on Sundays or public holidays. Transactional messages such as OTPs run 24/7. ### What is the Registro de Números Excluidos? It is the CRC register where people enrol their numbers to avoid advertising. Check your lists against it and confirm the current process on the CRC site, since operators may filter excluded numbers. ### Do I need consent to send promotional SMS in Colombia? Treat it as required. Law 1581 of 2012 requires prior, informed authorisation, obtained in a way that can be consulted later, unless an exception applies. Keep the wording, timestamp, channel and number for each opt-in. ### Can I use a short code in Colombia? Short codes and numeric long codes are available alongside alphanumeric IDs where supported. Short codes suit high-volume or two-way programmes. The operators set the requirements, and the typical lead time is 5 to 10 business days. ### Why does my Spanish SMS split into two parts? Letters such as á, í, ó and ú are outside the default GSM 7-bit alphabet, so one of them makes the message Unicode, which holds 70 characters per message and 67 per part. Test the final copy in a character counter. ### Which Colombian networks does OmniChannels.ai reach? Claro Colombia, Movistar Colombia and Tigo Colombia, all over direct routes. Test every campaign on all three. ## Official sources - [Comisión de Regulación de Comunicaciones (CRC)](https://www.crcom.gov.co/) - [Ley 2300 de 2023, Función Pública](https://www.funcionpublica.gov.co/eva/gestornormativo/norma.php?i=213990) - [Ley 1581 de 2012, Función Pública](https://www.funcionpublica.gov.co/eva/gestornormativo/norma.php?i=49981) Updated: 2026-11-06
