Number format in Antigua and Barbuda

Antigua and Barbuda uses the North American Numbering Plan: +1, a three-digit area code and a seven-digit number, such as +1 268 464 1234. The API reads the area code (268 here) to price the number as Antigua and Barbuda 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 Antigua and Barbuda 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

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