Number format in Dominica

Dominica uses the North American Numbering Plan: +1, a three-digit area code and a seven-digit number, such as +1 767 225 1234. The API reads the area code (767 here) to price the number as Dominica rather than the United States, so keep the full eleven digits in your list.

Alphabet and segments

English text stays inside the GSM-7 alphabet, so one segment to Dominica 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

Dominica keeps UTC-4 all year with no clock change, so 09:00 in Dominica is always 13:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.

Send to Dominica with one request

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