SMS API for Singapore: bulk SMS to +65 numbers

Singapore, a global financial hub and Southeast Asia's tech leader, is centered around its capital city and port. Banks, e-commerce platforms, ride-hailing apps, and government agencies send SMS messages to users. These messages notify users of login attempts, payment confirmations, delivery updates, and public service announcements. SMS is chosen for its universal reach, ensuring messages are read quickly on any phone, including those used by tourists and expatriates.

Number format in Singapore

Mobile numbers in Singapore have 8 digits after +65 and no trunk prefix, so the local form 8123 4567 becomes +65 8123 4567 in the to field.

Alphabet and segments

English, Malay, Chinese and Tamil text stays inside the GSM-7 alphabet, so one segment to Singapore holds 160 characters and each part of a longer text 153. Watch for curly quotes and emoji copied from other tools: one of them moves the whole text to Unicode at 70 characters per segment, and POST /v1/estimates shows the encoding before you send.

Time zone and timing

Singapore keeps UTC+8 all year with no clock change, so 09:00 in Singapore is always 01:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.

Send to Singapore with one request

The answer comes back at once with the message id, the country the number was matched to (SG) 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.
