SMS API for Colombia: bulk SMS to +57 numbers

Colombia, located in South America, has Bogotá as its capital and is known for its coffee exports and growing tech sector. Software products like mobile banking apps, ride-hailing services, and e-commerce platforms rely on SMS for customer communication. Messages are triggered by events such as payment confirmations, delivery updates, and appointment reminders. SMS is preferred because it reaches all mobile users instantly, even those without smartphones or internet access.

Number format in Colombia

Mobile numbers in Colombia have 10 digits after +57 and no trunk prefix, so the local form 321 1234567 becomes +57 321 1234567 in the to field.

Alphabet and segments

Texts in Spanish fit 160 GSM-7 characters per segment until they use á, í, ó and ú: those letters are outside GSM-7 and turn the message into Unicode at 70 characters per segment (67 per part). For short alerts, write them without those letters to keep one segment; for longer texts, the console names each letter that changed the encoding.

Time zone and timing

Colombia keeps UTC-5 all year with no clock change, so 09:00 in Bogota is always 14:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.

Send to Colombia with one request

The answer comes back at once with the message id, the country the number was matched to (CO) and the price. A delivered or failed event follows on your webhook, and a failed message is refunded.

For a list, send the same text to up to 10,000 numbers with POST /v1/batches, or a personal text per number in messages.
