SMS API for Iran: bulk SMS to +98 numbers

Iran is a Middle Eastern country with Tehran as its capital, known for its oil industry and growing tech sector. Developers at mobile banking apps, e-commerce platforms, healthcare providers, and universities integrate SMS into their systems. Messages are sent for events like OTP logins, order confirmations, appointment reminders, and exam results. SMS is chosen because it works on all phones, reaches users in both urban and rural areas, and does not require an app.

Number format in Iran

Mobile numbers in Iran have 10 digits after +98. Locally they are written with a leading 0 (0912 345 6789); in the API that 0 is dropped, so the same number goes in the to field as +98 912 345 6789.

Alphabet and segments

Text in Persian (Arabic script) is always Unicode, so a message to Iran written in Persian carries 70 characters in one segment and 67 in each part of a longer one. Codes and alerts written in English or plain Latin letters fit 160 characters, which halves the cost of a long notice.

Time zone and timing

Iran keeps UTC+3:30 all year with no clock change, so 09:00 in Tehran is always 05:30 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.

Send to Iran with one request

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